GENERAL DESCRIPTION
The ADSP-TS201S TigerSHARC processor is an ultrahigh performance, static superscalar processor optimized for large signal processing tasks and communications infrastructure. The DSP combines very wide memory widths with dual computation blocks--supporting floating-point (IEEE 32-bit and extended precision 40-bit) and fixed-point (8-, 16-, 32-, and 64-bit) processing--to set a new standard of performance for digital signal processors. The TigerSHARC static superscalar architecture lets the DSP execute up to four instructions each cycle, performing 24 fixed-point (16-bit) operations or six floating-point operations. Four independent 128-bit wide internal data buses, each connecting to the six 4M bit memory banks, enable quad-word data, instruction, and I/O access and provide 33.6G bytes per second of internal memory bandwidth. Operating at 600 MHz, the ADSP-TS201S processor's core has a 1.67 ns instruction cycle time. Using its single-instruction, multiple-data (SIMD) features, the ADSP-TS201S processor can perform 4.8 billion, 40-bit MACS or 1.2 billion, 80-bit MACS per second.

DATA
ADSP-TS201S
The TigerSHARC DSP uses a Static SuperscalarTM architecture. This architecture is superscalar in that the ADSP-TS201S processor's core can execute simultaneously from one to four 32-bit instructions encoded in a very large instruction word (VLIW) instruction line using the DSP's dual compute blocks. Because the DSP does not perform instruction re-ordering at runtime-- the programmer selects which operations will execute in parallel prior to runtime--the order of instructions is static. With few exceptions, an instruction line, whether it contains one, two, three, or four 32-bit instructions, executes with a throughput of one cycle in a 10-deep processor pipeline. For optimal DSP program execution, programmers must follow the DSP's set of instruction parallelism rules when encoding an instruction line. In general, the selection of instructions that the DSP can execute in parallel each cycle depends on the instruction line resources each instruction requires and on the source and destination registers used in the instructions. The programmer has direct control of three core components--the IALUs, the compute blocks, and the program sequencer. The ADSP-TS201S processor, in most cases, has a two-cycle execution pipeline that is fully interlocked, so--whenever a computation result is unavailable for another operation dependent on it--the DSP automatically inserts one or more stall cycles as needed. Efficient programming with dependency-free instructions can eliminate most computational and memory transfer data dependencies. In addition, the ADSP-TS201S processor supports SIMD operations two ways--SIMD compute blocks and SIMD computations. The programmer can load both compute blocks with the same data (broadcast distribution) or different data (merged distribution). storing intermediate results. Instructions can access the registers in the register file individually (word-aligned), in sets of two (dual-aligned), or in sets of four (quad-aligned). * ALU--the ALU performs a standard set of arithmetic operations in both fixed- and floating-point formats. It also performs logic operations. * Multiplier--the multiplier performs both fixed- and floating-point multiplication and fixed-point multiply and accumulate. * Shifter--the 64-bit shifter performs logical and arithmetic shifts, bit and bit stream manipulation, and field deposit and extraction operations. * Communications Logic Unit (CLU)--this 128-bit unit provides trellis decoding (for example, Viterbi and Turbo decoders) and executes complex correlations for CDMA communication applications (for example, chip-rate and symbol-rate functions). Using these features, the compute blocks can: * Provide 8 MACS per cycle peak and 7.1 MACS per cycle sustained 16-bit performance and provide 2 MACS per cycle peak and 1.8 MACS per cycle sustained 32-bit performance (based on FIR) * Execute six single-precision floating-point or execute 24 fixed-point (16-bit) operations per cycle, providing 3.6G FLOPS or 14.4G/s regular operations performance at 600 MHz * Perform two complex 16-bit MACS per cycle * Execute eight trellis butterflies in one cycle
DATA ALIGNMENT BUFFER (DAB)
The DAB is a quad-word FIFO that enables loading of quadword data from nonaligned addresses. Normally, load instructions must be aligned to their data size so that quad words are loaded from a quad-aligned address. Using the DAB significantly improves the efficiency of some applications, such as FIR filters.
DUAL COMPUTE BLOCKS
The ADSP-TS201S processor has compute blocks that can execute computations either independently or together as a singleinstruction, multiple-data (SIMD) engine. The DSP can issue up to two compute instructions per compute block each cycle, instructing the ALU, multiplier, shifter, or CLU to perform independent, simultaneous operations. Each compute block can execute eight 8-bit, four 16-bit, two 32-bit, or one 64-bit SIMD computations in parallel with the operation in the other block. These computation units support IEEE 32-bit single-precision floating-point, extended-precision 40-bit floating point, and 8-, 16-, 32-, and 64-bit fixed-point processing. The compute blocks are referred to as X and Y in assembly syntax, and each block contains four computational units--an ALU, a multiplier, a 64-bit shifter, a 128-bit CLU--and a 32word register file. * Register File--each compute block has a multiported 32word, fully orthogonal register file used for transferring data between the computation units and data buses and for
DUAL INTEGER ALU (IALU)
The ADSP-TS201S processor has two IALUs that provide powerful address generation capabilities and perform many generalpurpose integer operations. The IALUs are referred to as J and K in assembly syntax and have the following features: * Provide memory addresses for data and update pointers * Support circular buffering and bit-reverse addressing * Perform general-purpose integer operations, increasing programming flexibility * Include a 31-word register file for each IALU As address generators, the IALUs perform immediate or indirect (pre- and post-modify) addressing. They perform modulus and bit-reverse operations with no constraints placed on memory addresses for the modulus data buffer placement. Each IALU can specify either a single-, dual-, or quad-word access from memory.

ADSP-TS201S
The IALUs have hardware support for circular buffers, bit reverse, and zero-overhead looping. Circular buffers facilitate efficient programming of delay lines and other data structures required in digital signal processing, and they are commonly used in digital filters and Fourier transforms. Each IALU provides registers for four circular buffers, so applications can set up a total of eight circular buffers. The IALUs handle address pointer wraparound automatically, reducing overhead, increasing performance, and simplifying implementation. Circular buffers can start and end at any memory location. Because the IALU's computational pipeline is one cycle deep, in most cases integer results are available in the next cycle. Hardware (register dependency check) causes a stall if a result is unavailable in a given cycle. The DSP distinguishes between hardware interrupts and software exceptions, handling them differently. When a software exception occurs, the DSP aborts all other instructions in the instruction pipe. When a hardware interrupt occurs, the DSP continues to execute instructions already in the instruction pipe.
Flexible Instruction Set
The 128-bit instruction line, which can contain up to four 32-bit instructions, accommodates a variety of parallel operations for concise programming. For example, one instruction line can direct the DSP to conditionally execute a multiply, an add, and a subtract in both computation blocks while it also branches to another location in the program. Some key features of the instruction set include: * CLU instructions for communications infrastructure to govern trellis decoding (for example, Viterbi and Turbo decoders) and despreading via complex correlations * Algebraic assembly language syntax * Direct support for all DSP, imaging, and video arithmetic types * Eliminates toggling DSP hardware modes because modes are supported as options (for example, rounding, saturation, and others) within instructions * Branch prediction encoded in instruction; enables zerooverhead loops * Parallelism encoded in instruction line * Conditional execution optional for all instructions * User-defined partitioning between program and data memory
PROGRAM SEQUENCER
The ADSP-TS201S processor's program sequencer supports the following: * A fully interruptible programming model with flexible programming in assembly and C/C++ languages; handles hardware interrupts with high throughput and no aborted instruction cycles * A 10-cycle instruction pipeline--four-cycle fetch pipe and six-cycle execution pipe--computation results available two cycles after operands are available * Supply of instruction fetch memory addresses; the sequencer's instruction alignment buffer (IAB) caches up to five fetched instruction lines waiting to execute; the program sequencer extracts an instruction line from the IAB and distributes it to the appropriate core component for execution * Management of program structures and program flow determined according to JUMP, CALL, RTI, RTS instructions, loop structures, conditions, interrupts, and software exceptions * Branch prediction and a 128-entry branch target buffer (BTB) to reduce branch delays for efficient execution of conditional and unconditional branch instructions and zero-overhead looping; correctly predicted branches occur with zero overhead cycles, overcoming the five-to-nine stage branch penalty * Compact code without the requirement to align code in memory; the IAB handles alignment
DSP MEMORY
The DSP's internal and external memory is organized into a unified memory map, which defines the location (address) of all elements in the system, as shown in Figure 3. The memory map is divided into four memory areas--host space, external memory, multiprocessor space, and internal memory--and each memory space, except host memory, is subdivided into smaller memory spaces. The ADSP-TS201S processor internal memory has 24M bits of on-chip DRAM memory, divided into six blocks of 4M bits (128K words x 32 bits). Each block--M0, M2, M4, M6, M8, and M10--can store program instructions, data, or both, so applications can configure memory to suit specific needs. Placing program instructions and data in different memory blocks, however, enables the DSP to access data while performing an instruction fetch. Each memory segment contains a 128K bit cache to enable single cycle access to internal DRAM. The six internal memory blocks connect to the four 128-bit wide internal buses through a crossbar connection, enabling the DSP to perform four memory transfers in the same cycle. The DSP's internal bus architecture provides a total memory bandwidth of
Interrupt Controller
The DSP supports nested and nonnested interrupts. Each interrupt type has a register in the interrupt vector table. Also, each has a bit in both the interrupt latch register and the interrupt mask register. All interrupts are fixed as either level-sensitive or edge-sensitive, except the IRQ3-0 hardware interrupts, which are programmable.

33.6G bytes per second, enabling the core and I/O to access eight 32-bit data-words and four 32-bit instructions each cycle. The DSP's flexible memory structure enables: * DSP core and I/O accesses to different memory blocks in the same cycle * DSP core access to three memory blocks in parallel--one instruction and two data accesses * Programmable partitioning of program and data memory * Program access of all memory as 32-, 64-, or 128-bit words--16-bit words with the DAB
The separate on-chip buses--four 128-bit data buses and four 32-bit address buses--are multiplexed at the SOC interface and transferred to the external port over the SOC bus to create an external system bus transaction. The external system bus provides a single 64-bit data bus and a single 32-bit address bus. The external port supports data transfer rates of 1G byte per second over the external bus. The external bus can be configured for 32-bit or 64-bit, littleendian operations. When the system bus is configured for 64-bit operations, the lower 32 bits of the external data bus connect to even addresses, and the upper 32 bits connect to odd addresses. The external port supports pipelined, slow, and SDRAM protocols. Addressing of external memory devices and memorymapped peripherals is facilitated by on-chip decoding of high order address lines to generate memory bank select signals.
EXTERNAL PORT (OFF-CHIP MEMORY/PERIPHERALS INTERFACE)
The ADSP-TS201S processor's external port provides the DSP's interface to off-chip memory and peripherals. The 4G word address space is included in the DSP's unified address space.

ADSP-TS201S
The ADSP-TS201S processor provides programmable memory, pipeline depth, and idle cycle for synchronous accesses; and external acknowledge controls to support interfacing to pipelined or slow devices, host processors, and other memorymapped peripherals with variable access, hold, and disable time requirements. The DSP's four link ports provide a second path for interprocessor communications with throughput of 4G bytes per second. The cluster bus provides 1G byte per second throughput--with a total of 4.8G bytes per second interprocessor bandwidth (limited by SOC bandwidth).
SDRAM Controller
The SDRAM controller controls the ADSP-TS201S processor's transfers of data to and from external synchronous DRAM (SDRAM) at a throughput of 32 bits or 64 bits per SCLK cycle using the external port and SDRAM control pins. The SDRAM interface provides a glueless interface with standard SDRAMs--16M bit, 64M bit, 128M bit, 256M bit, and 512M bit. The DSP supports directly a maximum of four banks of 64M words x 32 bits of SDRAM. The SDRAM interface is mapped in external memory in each DSP's unified memory map.
Host Interface
The ADSP-TS201S processor provides an easy and configurable interface between its external bus and host processors through the external port (see Figure 4). To accommodate a variety of host processors, the host interface supports pipelined or slow protocols for ADSP-TS201S processor access of the host as slave or pipelined for host access of the ADSP-TS201S processor as slave. Each protocol has programmable transmission parameters, such as idle cycles, pipe depth, and internal wait cycles. The host interface supports burst transactions initiated by a host processor. After the host issues the starting address of the burst and asserts the BRST signal, the DSP increments the address internally while the host continues to assert BRST. The host interface provides a deadlock recovery mechanism that enables a host to recover from deadlock situations involving the DSP. The BOFF signal provides the deadlock recovery mechanism. When the host asserts BOFF, the DSP backs off the current transaction and asserts HBG and relinquishes the external bus. The host can directly read or write the internal memory of the ADSP-TS201S processor, and it can access most of the DSP registers, including DMA control (TCB) registers. Vector interrupts support efficient execution of host commands.
EPROM Interface
The ADSP-TS201S processor can be configured to boot from an external 8-bit EPROM at reset through the external port. An automatic process (which follows reset) loads a program from the EPROM into internal memory. This process uses 16 wait cycles for each read access. During booting, the BMS pin functions as the EPROM chip select signal. The EPROM boot procedure uses DMA Channel 0, which packs the bytes into 32-bit instructions. Applications can also access the EPROM (write flash memories) during normal operation through DMA. The EPROM or flash memory interface is not mapped in the DSP's unified memory map. It is a byte address space limited to a maximum of 16M bytes (24 address bits). The EPROM or flash memory interface can be used after boot via a DMA.
Multiprocessor Interface
The ADSP-TS201S processor offers powerful features tailored to multiprocessing DSP systems through the external port and link ports (see Figure 4). This multiprocessing capability provides the highest bandwidth for interprocessor communication, including: * Up to eight DSPs on a common bus * On-chip arbitration for glueless multiprocessing * Link ports for point-to-point communication The external port and link ports provide integrated, glueless multiprocessing support. The external port supports a unified address space (see Figure 3) that enables direct interprocessor accesses of each ADSP-TS201S processor's internal memory and registers. The DSP's on-chip distributed bus arbitration logic provides simple, glueless connection for systems containing up to eight ADSP-TS201S processors and a host processor. Bus arbitration has a rotating priority. Bus lock supports indivisible readmodify-write sequences for semaphores. A bus fairness feature prevents one DSP from holding the external bus too long.
DMA CONTROLLER
The ADSP-TS201S processor's on-chip DMA controller, with 14 DMA channels, provides zero-overhead data transfers without processor intervention. The DMA controller operates independently and invisibly to the DSP's core, enabling DMA operations to occur while the DSP's core continues to execute program instructions. The DMA controller performs DMA transfers between internal memory, external memory, and memory-mapped peripherals; the internal memory of other DSPs on a common bus, a host processor, or link port I/O; between external memory and external peripherals or link port I/O; and between an external bus master and internal memory or link port I/O. The DMA controller performs the following DMA operations: * External port block transfers. Four dedicated bidirectional DMA channels transfer blocks of data between the DSP's internal memory and any external memory or memorymapped peripheral on the external bus. These transfers support master mode and handshake mode protocols. * Link port transfers. Eight dedicated DMA channels (four transmit and four receive) transfer quad-word data only between link ports and between a link port and internal or

external memory. These transfers only use handshake mode protocol. DMA priority rotates between the four receive channels. * AutoDMA transfers. Two dedicated unidirectional DMA channels transfer data received from an external bus master to internal memory or to link port I/O. These transfers only use slave mode protocol, and an external bus master must initiate the transfer. The DMA controller provides these additional features: * Flyby transfers. Flyby operations only occur through the external port (DMA Channel 0) and do not involve the DSP's core. The DMA controller acts as a conduit to transfer data from an I/O device to external SDRAM memory.
During a transaction, the DSP relinquishes the external data bus; outputs addresses and memory selects (MSSD3-0); outputs the IORD, IOWR, IOEN, and RD/WR strobes; and responds to ACK. * DMA chaining. DMA chaining operations enable applications to automatically link one DMA transfer sequence to another for continuous transmission. The sequences can occur over different DMA channels and have different transmission attributes. * Two-dimensional transfers. The DMA controller can access and transfer two-dimensional memory arrays on any DMA transmit or receive channel. These transfers are implemented with index, count, and modify registers for both the X and Y dimensions.

LINK PORTS (LVDS)
The DSP's four full-duplex link ports each provide additional four-bit receive and four-bit transmit I/O capability, using low voltage, differential-signal (LVDS) technology. With the ability to operate at a double data rate--latching data on both the rising and falling edges of the clock--running at up to 500 MHz, each link port can support up to 500M bytes per second per direction, for a combined maximum throughput of 4G bytes per second. The link ports provide an optional communications channel that is useful in multiprocessor systems for implementing pointto-point interprocessor communications. Applications can also use the link ports for booting. Each link port has its own triple-buffered quad-word input and double-buffered quad-word output registers. The DSP's core can write directly to a link port's transmit register and read from a receive register, or the DMA controller can perform DMA transfers through eight (four transmit and four receive) dedicated link port DMA channels. Each link port direction has three signals that control its operation. For the transmitter, LxCLKOUT is the output transmit clock, LxACKI is the handshake input to control the data flow, and the LxBCMPO output indicates that the block transfer is complete. For the receiver, LxCLKIN is the input receive clock, LxACKO is the handshake output to control the data flow, and the LxBCMPI input indicates that the block transfer is complete. The LxDATO3-0 pins are the data output bus for the transmitter and the LxDATI3-0 pins are the input data bus for the receiver. Applications can program separate error detection mechanisms for transmit and receive operations (applications can use the checksum mechanism to implement consecutive link port transfers), the size of data packets, and the speed at which bytes are transmitted. After reset, the ADSP-TS201S processor has four boot options for beginning operation: * Boot from EPROM. * Boot by an external master (host or another ADSP-TS201S processor). * Boot by link port. * No boot--start running from memory address selected with one of the IRQ3-0 interrupt signals. See Table 2. Using the "no boot" option, the ADSP-TS201S processor must start running from memory when one of the interrupts is asserted. Table 2. No Boot, Run from Memory Addresses
Interrupt IRQ0 IRQ1 IRQ2 IRQ3 Address 0x3000 0000 (External Memory) 0x3800 0000 (External Memory) 0x8000 0000 (External Memory) 0x0000 0000 (Internal Memory)
The ADSP-TS201S processor core always exits from reset in the idle state and waits for an interrupt. Some of the interrupts in the interrupt vector table are initialized and enabled after reset. For more information on boot options, see the EE-200: ADSP-TS20x TigerSHARC Processor Boot Loader Kernels Operation on the Analog Devices website (www.analog.com).
CLOCK DOMAINS
The DSP uses calculated ratios of the SCLK clock to operate, as shown in Figure 5. The instruction execution rate is equal to CCLK. A PLL from SCLK generates CCLK which is phaselocked. The SCLKRATx pins define the clock multiplication of SCLK to CCLK (see Table 4 on Page 12). The link port clock is generated from CCLK via a software programmable divisor, and the SOC bus operates at 1/2 CCLK. Memory transfers to external and link port buffers operate at the SOCCLK rate. SCLK also provides clock input for the external bus interface and defines the ac specification reference for the external bus signals. The external bus interface runs at the SCLK frequency. The maximum SCLK frequency is one quarter the internal DSP clock (CCLK) frequency.
EXTERNAL INTERFACE
TIMER AND GENERAL-PURPOSE I/O
The ADSP-TS201S processor has a timer pin (TMR0E) that generates output when a programmed timer counter has expired, and four programmable general-purpose I/O pins (FLAG3-0) that can function as either single-bit input or output. As outputs, these pins can signal peripheral devices; as inputs, they can provide the test for conditional branching.
RESET AND BOOTING
The ADSP-TS201S processor has three levels of reset: * Power-up reset - after power-up of the system (SCLK, all static inputs, and strap pins are stable), the RST_IN pin must be asserted (low). * Normal reset - for any chip reset following the power-up reset, the RST_IN pin must be asserted (low). * DSP-core reset - when setting the SWRST bit in EMUCTL, the DSP core is reset, but not the external port or I/O. For normal operations, tie the RST_OUT pin to the POR_IN pin.

POWER DOMAINS
The ADSP-TS201S processor has separate power supply connections for internal logic (VDD), analog circuits (VDD_A), I/O buffer (VDD_IO), and internal DRAM (VDD_DRAM) power supply. Note that the analog (VDD_A) supply powers the clock generator PLLs. To produce a stable clock, systems must provide a clean power supply to power input VDD_A. Designs must pay critical attention to bypassing the VDD_A supply. The VisualDSP++ project management environment lets programmers develop and debug an application. This environment includes an easy to use assembler (which is based on an algebraic syntax), an archiver (librarian/library builder), a linker, a loader, a cycle-accurate instruction-level simulator, a C/C++ compiler, and a C/C++ run-time library that includes DSP and mathematical functions. A key point for theses tools is C/C++ code efficiency. The compiler has been developed for efficient translation of C/C++ code to DSP assembly. The DSP has architectural features that improve the efficiency of compiled C/C++ code. The VisualDSP++ debugger has a number of important features. Data visualization is enhanced by a plotting package that offers a significant level of flexibility. This graphical representation of user data enables the programmer to quickly determine the performance of an algorithm. As algorithms grow in complexity, this capability can have increasing significance on the designer's development schedule, increasing productivity. Statistical profiling enables the programmer to nonintrusively poll the processor as it is running the program. This feature, unique to VisualDSP++, enables the software developer to passively gather important code execution metrics without interrupting the real-time characteristics of the program. Essentially, the developer can identify bottlenecks in software quickly and efficiently. By using the profiler, the programmer can focus on those areas in the program that impact performance and take corrective action. Debugging both C/C++ and assembly programs with the VisualDSP++ debugger, programmers can:

eliminating the need to start from the very beginning when developing new application code. The VDK features include threads, critical and unscheduled regions, semaphores, events, and device flags. The VDK also supports priority-based, preemptive, cooperative, and time-sliced scheduling approaches. In addition, the VDK was designed to be scalable. If the application does not use a specific feature, the support code for that feature is excluded from the target system. Because the VDK is a library, a developer can decide whether to use it or not. The VDK is integrated into the VisualDSP++ development environment, but can also be used via standard command line tools. When the VDK is used, the development environment assists the developer with many error-prone tasks and assists in managing system resources, automating the generation of various VDK-based objects, and visualizing the system state, when debugging an application that uses the VDK. VCSE is Analog Devices' technology for creating, using, and reusing software components (independent modules of substantial functionality) to quickly and reliably assemble software applications. It also is used for downloading components from the Web, dropping them into the application, and publishing component archives from within VisualDSP++. VCSE supports component implementation in C/C++ or assembly language. Use the expert linker to visually manipulate the placement of code and data on the embedded system, view memory use in a color-coded graphical form, easily move code and data to different areas of the DSP or external memory with a drag of the mouse, and examine runtime stack and heap usage. The expert linker is fully compatible with existing linker definition file (LDF), allowing the developer to move between the graphical and textual environments. Analog Devices DSP emulators use the IEEE 1149.1 JTAG test access port of the ADSP-TS201S processor to monitor and control the target board processor during emulation. The emulator provides full speed emulation, allowing inspection and modification of memory, registers, and processor stacks. Nonintrusive in-circuit emulation is assured by the use of the processor's JTAG interface--the emulator does not affect target system loading or timing. In addition to the software and hardware development tools available from Analog Devices, third parties provide a wide range of tools supporting the TigerSHARC processor family. Hardware tools include TigerSHARC processor PC plug-in cards. Third party software tools include DSP libraries, realtime operating systems, and block diagram design tools. are sample application programs, power supply, and a USB cable. All evaluation versions of the software tools are limited for use only with the EZ-KIT Lite product. The USB controller on the EZ-KIT Lite board connects the board to the USB port of the user's PC, enabling the VisualDSP++ evaluation suite to emulate the on-board processor in-circuit. This permits the customer to download, execute, and debug programs for the EZ-KIT Lite system. It also allows in-circuit programming of the on-board flash device to store user-specific boot code, enabling the board to run as a standalone unit, without being connected to the PC. With a full version of VisualDSP++ installed (sold separately), engineers can develop software for the EZ-KIT Lite or any custom-defined system. Connecting one of Analog Devices JTAG emulators to the EZ-KIT Lite board enables high speed, nonintrusive emulation.
DESIGNING AN EMULATOR-COMPATIBLE DSP BOARD (TARGET)
The Analog Devices family of emulators are tools that every DSP developer needs in order to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG test access port (TAP) on each JTAG DSP. The emulator uses the TAP to access the internal features of the DSP, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The DSP must be halted to send data and commands, but once an operation has been completed by the emulator, the DSP system is set running at full speed with no impact on system timing. To use these emulators, the target board must include a header that connects the DSP's JTAG port to the emulator. For details on target board design issues including mechanical layout, single processor connections, multiprocessor scan chains, signal buffering, signal termination, and emulator pod logic, see the EE-68: Analog Devices JTAG Emulation Technical Reference on the Analog Devices website (www.analog.com)-- use the string "EE-68" in site search. This document is updated regularly to keep pace with improvements to emulator support.

PIN FUNCTION DESCRIPTIONS
While most of the ADSP-TS201S processor's input pins are normally synchronous--tied to a specific clock--a few are asynchronous. For these asynchronous signals, an on-chip synchronization circuit prevents metastability problems. Use the ac specification for asynchronous signals when the system design requires predictable, cycle-by-cycle behavior for these signals. Table 3. Pin Definitions--Clocks and Reset
Description Core Clock Ratio. The DSP's core clock (CCLK) rate = n x SCLK, where n is userprogrammable using the SCLKRATx pins to the values shown in Table 4. These pins may change only during reset; connect these pins to VDD_IO or VSS. All reset specifications in Table 25, Table 26, and Table 27 must be satisfied. The core clock rate (CCLK) is the instruction cycle rate. SCLK I na System Clock Input. The DSP's system input clock for cluster bus. The core clock rate is user-programmable using the SCLKRATx pins. For more information, see Clock Domains on Page 9. RST_IN I/A na Reset. Sets the DSP to a known state and causes program to be in idle state. RST_IN must be asserted a specified time according to the type of reset operation. For details, see Reset and Booting on Page 9, Table 25 on Page 26, and Figure 13 on Page 26. RST_OUT O na Reset Output. Indicates that the DSP reset is complete. Connect to POR_IN. POR_IN I/A na Power-On Reset for internal DRAM. Connect to RST_OUT. I = input; A = asynchronous; O = output; OD = open-drain output; T = three-state; P = power supply; G = ground; pd = internal pull-down 5 k; pu = internal pull-up 5 k; pd_0 = internal pull-down 5 k on DSP ID = 0; pu_0 = internal pull-up 5 k on DSP ID = 0; pu_od_0 = internal pull-up 500 on DSP ID = 0; pd_m = internal pull-down 5 k on DSP bus master; pu_m = internal pull-up 5 k on DSP bus master; pu_ad = internal pull-up 40 k. For more pull-down and pull-up information, see Electrical Characteristics on Page 22.

The output pins can be three-stated during normal operation. The DSP three-states all output pins during reset, allowing these pins to get to their internal pull-up or pull-down state. Some pins have an internal pull-up or pull-down resistor (30% tolerance) that maintains a known value during transitions between different drivers.

ADSP-TS201S
Table 5. Pin Definitions--External Port Bus Controls
Description Address Bus. The DSP issues addresses for accessing memory and peripherals on these pins. In a multiprocessor system, the bus master drives addresses for accessing internal memory or I/O processor registers of other ADSP-TS201S processors. The DSP inputs addresses when a host or another DSP accesses its internal memory or I/O processor registers. DATA63-0 I/O/T nc External Data Bus. The DSP drives and receives data and instructions on these pins. (pu_ad) Pull-up or pull-down resistors on unused DATA pins are unnecessary. RD I/O/T epu1 Memory Read. RD is asserted whenever the DSP reads from any slave in the system, (pu_0) excluding SDRAM. When the DSP is a slave, RD is an input and indicates read transactions that access its internal memory or universal registers. In a multiprocessor system, the bus master drives RD. RD changes concurrently with ADDR pins. WRL I/O/T epu1 Write Low. WRL is asserted in two cases: when the ADSP-TS201S processor writes to (pu_0) an even address word of external memory or to another external bus agent; and when the ADSP-TS201S processor writes to a 32-bit zone (host, memory, or DSP programmed to 32-bit bus). An external master (host or DSP) asserts WRL for writing to a DSP's low word of internal memory. In a multiprocessor system, the bus master drives WRL. WRL changes concurrently with ADDR pins. When the DSP is a slave, WRL is an input and indicates write transactions that access its internal memory or universal registers. WRH I/O/T epu1 Write High. WRH is asserted when the ADSP-TS201S processor writes a long word (pu_0) (64 bits) or writes to an odd address word of external memory or to another external bus agent on a 64-bit data bus. An external master (host or another DSP) must assert WRH for writing to a DSP's high word of 64-bit data bus. In a multiprocessing system, the bus master drives WRH. WRH changes concurrently with ADDR pins. When the DSP is a slave, WRH is an input and indicates write transactions that access its internal memory or universal registers. ACK I/O/T/OD epu1 Acknowledge. External slave devices can deassert ACK to add wait states to external (pu_od_0) memory accesses. ACK is used by I/O devices, memory controllers, and other peripherals on the data phase. The DSP can deassert ACK to add wait states to read and write accesses of its internal memory. The pull-up is 50 on low-to-high transactions and is 500 on all other transactions. O/T na Boot Memory Select. BMS is the chip select for boot EPROM or flash memory. During BMS (pu_0) reset, the DSP uses BMS as a strap pin (EBOOT) for EPROM boot mode. In a multiprocessor system, the DSP bus master drives BMS. For details, see Reset and Booting on Page 9 and the EBOOT signal description in Table 16 on Page 20. MS1-0 O/T nc Memory Select. MS0 or MS1 is asserted whenever the DSP accesses memory banks 0 (pu_0) or 1, respectively. MS1-0 are decoded memory address pins that change concurrently with ADDR pins. When ADDR31:27 = 0b00110, MS0 is asserted. When ADDR31:27 = 0b00111, MS1 is asserted. In multiprocessor systems, the master DSP drives MS1-0. MSH O/T nc Memory Select Host. MSH is asserted whenever the DSP accesses the host address (pu_0) space (ADDR31 = 0b1). MSH is a decoded memory address pin that changes concurrently with ADDR pins. In a multiprocessor system, the bus master DSP drives MSH. BRST I/O/T epu1 Burst. The current bus master (DSP or host) asserts this pin to indicate that it is reading (pu_0) or writing data associated with consecutive addresses. A slave device can ignore addresses after the first one and increment an internal address counter after each transfer. For host-to-DSP burst accesses, the DSP increments the address automatically while BRST is asserted. I = input; A = asynchronous; O = output; OD = open-drain output; T = three-state; P = power supply; G = ground; pd = internal pull-down 5 k; pu = internal pull-up 5 k; pd_0 = internal pull-down 5 k on DSP ID = 0; pu_0 = internal pull-up 5 k on DSP ID = 0; pu_od_0 = internal pull-up 500 on DSP ID = 0; pd_m = internal pull-down 5 k on DSP bus master; pu_m = internal pull-up 5 k on DSP bus master; pu_ad = internal pull-up 40 k. For more pull-down and pull-up information, see Electrical Characteristics on Page 22. Term (termination of unused pins) column symbols: epd = external pull-down approximately 5 k to VSS; epu = external pull-up approximately 5 k to VDD_IO, nc = not connected; na = not applicable (always used); VDD_IO = connect directly to VDD_IO; VSS = connect directly to VSS

Table 6. Pin Definitions--External Port Arbitration
Description Multiprocessing Bus Request Pins. Used by the DSPs in a multiprocessor system to arbitrate for bus mastership. Each DSP drives its own BRx line (corresponding to the value of its ID2-0 inputs) and monitors all others. In systems with fewer than eight DSPs, set the unused BRx pins high (VDD_IO). ID2-0 I (pd) na Multiprocessor ID. Indicates the DSP's ID, from which the DSP determines its order in a multiprocessor system. These pins also indicate to the DSP which bus request (BR0-BR7) to assert when requesting the bus: 000 = BR0, 001 = BR1, 010 = BR2, 011 = BR3, 100 = BR4, 101 = BR5, 110 = BR6, or 111 = BR7. ID2-0 must have a constant value during system operation and can change during reset only. BM O na Bus Master. The current bus master DSP asserts BM. For debugging only. At reset this is a strap pin. For more information, see Table 16 on Page 20. BOFF I epu Back Off. A deadlock situation can occur when the host and a DSP try to read from each other's bus at the same time. When deadlock occurs, the host can assert BOFF to force the DSP to relinquish the bus before completing its outstanding transaction. BUSLOCK O/T na Bus Lock Indication. Provides an indication that the current bus master has locked the (pu_0) bus. At reset, this is a strap pin. For more information, see Table 16 on Page 20. HBR I epu Host Bus Request. A host must assert HBR to request control of the DSP's external bus. When HBR is asserted in a multiprocessing system, the bus master relinquishes the bus and asserts HBG once the outstanding transaction is finished. HBG I/O/T epu2 Host Bus Grant. Acknowledges HBR and indicates that the host can take control of (pu_0) the external bus. When relinquishing the bus, the master DSP three-states the ADDR31-0, DATA63-0, MSH, MSSD3-0, MS1-0, RD, WRL, WRH, BMS, BRST, IORD, IOWR, IOEN, RAS, CAS, SDWE, SDA10, SDCKE, LDQM, and HDQM pins, and the DSP puts the SDRAM in self-refresh mode. The DSP asserts HBG until the host deasserts HBR. In multiprocessor systems, the current bus master DSP drives HBG, and all slave DSPs monitor it. CPA I/O/OD epu2 Core Priority Access. Asserted while the DSP's core accesses external memory. This (pu_od_0) pin enables a slave DSP to interrupt a master DSP's background DMA transfers and gain control of the external bus for core-initiated transactions. CPA is an open drain output, connected to all DSPs in the system. If not required in the system, leave CPA unconnected (external pull-ups will be required for DSP ID = 1 through ID = 7). I/O/OD epu2 DMA Priority Access. Asserted while a high priority DSP DMA channel accesses DPA (pu_od_0) external memory. This pin enables a high priority DMA channel on a slave DSP to interrupt transfers of a normal priority DMA channel on a master DSP and gain control of the external bus for DMA-initiated transactions. DPA is an open drain output, connected to all DSPs in the system. If not required in the system, leave DPA unconnected (external pull-ups will be required for DSP ID = 1 through ID = 7). I = input; A = asynchronous; O = output; OD = open-drain output; T = three-state; P = power supply; G = ground; pd = internal pull-down 5 k; pu = internal pull-up 5 k; pd_0 = internal pull-down 5 k on DSP ID = 0; pu_0 = internal pull-up 5 k on DSP ID = 0; pu_od_0 = internal pull-up 500 on DSP ID = 0; pd_m = internal pull-down 5 k on DSP bus master; pu_m = internal pull-up 5 k on DSP bus master; pu_ad = internal pull-up 40 k. For more pull-down and pull-up information, see Electrical Characteristics on Page 22. Term (termination of unused pins) column symbols: epd = external pull-down approximately 5 k to VSS; epu = external pull-up approximately 5 k to VDD_IO, nc = not connected; na = not applicable (always used); VDD_IO = connect directly to VDD_IO; VSS = connect directly to VSS

Table 7. Pin Definitions--External Port DMA/Flyby
Description DMA Request Pins. Enable external I/O devices to request DMA services from the DSP. In response to DMARx, the DSP performs DMA transfers according to the DMA channel's initialization. The DSP ignores DMA requests from uninitialized channels. IOWR O/T nc I/O Write. When a DSP DMA channel initiates a flyby mode read transaction, the DSP (pu_0) asserts the IOWR signal during the data cycles. This assertion makes the I/O device sample the data instead of the TigerSHARC. IORD O/T nc I/O Read. When a DSP DMA channel initiates a flyby mode write transaction, the DSP (pu_0) asserts the IORD signal during the data cycle. This assertion with the IOEN makes the I/O device drive the data instead of the TigerSHARC. O/T nc I/O Device Output Enable. Enables the output buffers of an external I/O device for flyIOEN (pu_0) by transactions between the device and external memory. Active on flyby transactions. I = input; A = asynchronous; O = output; OD = open-drain output; T = three-state; P = power supply; G = ground; pd = internal pull-down 5 k; pu = internal pull-up 5 k; pd_0 = internal pull-down 5 k on DSP ID = 0; pu_0 = internal pull-up 5 k on DSP ID = 0; pu_od_0 = internal pull-up 500 on DSP ID = 0; pd_m = internal pull-down 5 k on DSP bus master; pu_m = internal pull-up 5 k on DSP bus master; pu_ad = internal pull-up 40 k.

Table 8. Pin Definitions--External Port SDRAM Controller
Description Memory Select SDRAM. MSSD0, MSSD1, MSSD2, or MSSD3 is asserted whenever the DSP accesses SDRAM memory space. MSSD3-0 are decoded memory address pins that are asserted whenever the DSP issues an SDRAM command cycle (access to ADDR31:30 = 0b01--except reserved spaces shown in Figure 3 on Page 6). In a multiprocessor system, the master DSP drives MSSD3-0. RAS I/O/T nc Row Address Select. When sampled low, RAS indicates that a row address is valid in (pu_0) a read or write of SDRAM. In other SDRAM accesses, it defines the type of operation to execute according to SDRAM specification. CAS I/O/T nc Column Address Select. When sampled low, CAS indicates that a column address is (pu_0) valid in a read or write of SDRAM. In other SDRAM accesses, it defines the type of operation to execute according to the SDRAM specification. LDQM O/T nc Low Word SDRAM Data Mask. When sampled high, three-states the SDRAM DQ (pu_0) buffers. LDQM is valid on SDRAM transactions when CAS is asserted, and inactive on read transactions. On write transactions, LDQM is active when accessing an odd address word on a 64-bit memory bus to disable the write of the low word. HDQM O/T nc High Word SDRAM Data Mask. When sampled high, three-states the SDRAM DQ (pu_0) buffers. HDQM is valid on SDRAM transactions when CAS is asserted, and inactive on read transactions. On write transactions, HDQM is active when accessing an even address in word accesses or when memory is configured for a 32-bit bus to disable the write of the high word. SDA10 O/T nc SDRAM Address Bit 10. Separate A10 signals enable SDRAM refresh operation while (pu_0) the DSP executes non-SDRAM transactions. SDCKE I/O/T nc SDRAM Clock Enable. Activates the SDRAM clock for SDRAM self-refresh or suspend (pu_m/ modes. A slave DSP in a multiprocessor system does not have the pull-up or pullpd_m) down. A master DSP (or ID = 0 in a single processor system) has a pull-up before granting the bus to the host, except when the SDRAM is put in self refresh mode. In self refresh mode, the master has a pull-down before granting the bus to the host. SDWE I/O/T nc SDRAM Write Enable.

STRAP PIN FUNCTION DESCRIPTIONS
Some pins have alternate functions at reset. Strap options set DSP operating modes. During reset, the DSP samples the strap option pins. Strap pins have an internal pull-up or pull-down for the default value. If a strap pin is not connected to an overdriving external pull-up, pull-down, or logic load, the DSP samples the default value during reset. If strap pins are Table 16. Pin Definitions--I/O Strap Pins

BMS Description EPROM Boot. 0 = boot from EPROM immediately after reset (default) 1 = idle after reset and wait for an external device to boot DSP through the external port or a link port Interrupt Enable. 0 = disable and set IRQ3-0 interrupts to edge-sensitive after reset (default) 1 = enable and set IRQ3-0 interrupts to level-sensitive immediately after reset Link Port Input Default Data Width. 0 = 1-bit (default) 1 = 4-bit SYSCON and SDRCON Write Enable. 0 = one-time writable after reset (default) 1 = always writable Test Mode 1. Do not overdrive default value during reset.
connected to logic inputs, a stronger external pull-up or pulldown may be required to ensure default value depending on leakage and/or low level input current of the logic load. To set a mode other than the default mode, connect the strap pin to a sufficiently stronger external pull-up or pull-down. Table 16 lists and describes each of the DSP's strap pins.

TM1
When default configuration is used, no external resistor is needed on the strap pins. To apply other configurations, a 500 resistor connected to VDD_IO is required. If providing external pull-downs, do not strap these pins directly to VSS; the strap pins require 500 resistor straps. All strap pins are sampled on the rising edge of RST_IN (deassertion edge). Each pin latches the strapped pin state (state of the strap pin at the rising edge of RST_IN). Shortly after deassertion of RST_IN, these pins are reconfigured to their normal functionality. These strap pins have an internal pull-down resistor, pull-up resistor, or no-resistor (three-state) on each pin. The resistor type, which is connected to the I/O pad, depends on whether RST_IN is active (low) or if RST_IN is deasserted (high). Table 17 shows the resistors that are enabled during active reset and during normal operation.

The individual values cannot be combined for analysis of a single instance of overshoot or undershoot. The worst case observed value must fall within one of the voltages specified and the total duration of the overshoot or undershoot (exceeding the 100% case) must be less than or equal to the corresponding duty cycle. 2 Duty cycle refers to the percentage of time the signal exceeds the value for the 100% case. This is equivalent to the measured duration of a single instance of overshoot or undershoot as a percentage of the period of occurrence. The practical worst case for period of occurrence for either overshoot or undershoot is 2 x tSCLK.

TIMING SPECIFICATIONS
With the exception of DMAR3-0, IRQ3-0, TMR0E, and FLAG3-0 (input only) pins, all ac timing for the ADSP-TS201S processor is relative to a reference clock edge. Because input setup/hold, output valid/hold, and output enable/disable times are relative to a clock edge, the timing data for the ADSPTS201S processor has few calculated (formula-based) values. For information on ac timing, see General AC Timing. For information on link port transfer timing, see Link Port Low Voltage, Differential-Signal (LVDS) Electrical Characteristics, and Timing on Page 30. The general ac timing data appears in Table 22 and Table 29. All ac specifications are measured with the load specified in Figure 36 on Page 38, and with the output drive strength set to strength 4. In order to calculate the output valid and hold times for different load conditions and/or output drive strengths, refer to Figure 37 on Page 38 through Figure 44 on Page 39 (Rise and Fall Time vs. Load Capacitance) and Figure 45 on Page 39 (Output Valid vs. Load Capacitance and Drive Strength). The ac asynchronous timing data for the IRQ3-0, DMAR3-0, FLAG3-0, and TMR0E pins appears in Table 21.
General AC Timing
Timing is measured on signals when they cross the 1.25 V level as described in Figure 15 on Page 29. All delays (in nanoseconds) are measured between the point that the first signal reaches 1.25 V and the point that the second signal reaches 1.25 V. Table 21. AC Asynchronous Signal Specifications

These input pins have Schmitt triggers and therefore do not need to be synchronized to a clock reference. For output specifications on FLAG3-0 pins, see Table 29. 3 This pin is a strap option. During reset, an internal resistor pulls the pin low.

The external port protocols employ bus IDLE cycles for bus mastership transitions as well as slave access boundary crossings to avoid any potential bus contention. The apparent driver overlap, due to output disables being larger than output enables, is not actual. For input specifications on FLAG3-0 pins, see Table 21. 3 These input pins are asynchronous and therefore do not need to be synchronized to a clock reference. 4 For additional requirement details, see Reset and Booting on Page 9. 5 RST_IN clock reference is the falling edge of SCLK. 6 TDO output clock reference is the falling edge of TCK. 7 Reference clock depends on function. 8 These pins may change only during reset; recommend connecting it to VDD_IO/VSS. 9 STRAP pins include: BMS, BM, BUSLOCK, TMR0E, L1BCMPO, L2BCMPO, and L3BCMPO. 10 Specifications applicable during reset only. 11 JTAG system pins include: RST_IN, RST_OUT, POR_IN, IRQ3-0, DMAR3-0, HBR, BOFF, MS1-0, MSH, SDCKE, LDQM, HDQM, BMS, IOWR, IORD, BM, EMU, SDA10, IOEN, BUSLOCK, TMR0E, DATA63-0, ADDR31-0, RD, WRL, WRH, BRST, MSSD3-0, RAS, CAS, SDWE, HBG, BR7-0, FLAG3-0, L0DATOP3-0, L0DATON3-0, L1DATOP3-0, L1DATON3-0, L2DATOP3-0, L2DATON3-0, L3DATOP3-0, L3DATON3-0, L0CLKOUTP, L0CLKOUTN, L1CLKOUTP, L1CLKOUTN, L2CLKOUTP, L2CLKOUTN, L3CLKOUTP, L3CLKOUTN, L0ACKI, L1ACKI, L2ACKI, L3ACKI, L0DATIP3-0, L0DATIN3-0, L1DATIP3-0, L1DATIN3-0, L2DATIP3-0, L2DATIN3-0, L3DATIP3-0, L3DATIN3-0, L0CLKINP, L0CLKINN, L1CLKINP, L1CLKINN, L2CLKINP, L2CLKINN, L3CLKINP, L3CLKINN, L0ACKO, L1ACKO, L2ACKO, L3ACKO, ACK, CPA, DPA, L0BCMPO, L1BCMPO, L2BCMPO, L3BCMPO, L0BCMPI, L1BCMPI, L2BCMPI, L3BCMPI, ID2-0, CTRL_IMPD1-0, SCLKRAT2-0, DS2-0, ENEDREG. 12 JTAG system output timing clock reference is the falling edge of TCK.

OUTPUT DRIVE CURRENTS
Figure 26 through Figure 33 show typical I-V characteristics for the output drivers of the ADSP-TS201S processor. The curves in these diagrams represent the current drive capability of the output drivers as a function of output voltage over the range of drive strengths. Typical drive currents for intermediate temperatures (such as 85C) should be obtained from the curves using linear interpolation. For complete output driver characteristics, refer to the DSP's IBIS models, available on the Analog Devices website (www.analog.com).

Output Disable Time
Output pins are considered to be disabled when they stop driving, go into a high impedance state, and start to decay from their output high or low voltage. The time for the voltage on the bus to decay by V is dependent on the capacitive load, CL and the load current, IL. This decay time can be approximated by the following equation: t DECAY = ( C L V ) I L

The output disable time tDIS is the difference between tMEASURED_DIS and tDECAY as shown in Figure 35. The time tMEASURED_DIS is the interval from when the reference signal switches to when the output voltage decays V from the measured output high or output low voltage. tDECAY is calculated with test loads CL and IL, and with V equal to 0.4 V.

Output Enable Time
Output pins are considered to be enabled when they have made a transition from a high impedance state to when they start driving. The time for the voltage on the bus to ramp by V is dependent on the capacitive load, CL, and the drive current, ID. This ramp time can be approximated by the following equation: t RAMP = ( C L V ) I D The output enable time tENA is the difference between tMEASURED_ENA and tRAMP as shown in Figure 35. The time tMEASURED_ENA is the interval from when the reference signal switches to when the output voltage ramps V from the measured three-stated output level. tRAMP is calculated with test load CL, drive current ID, and with V equal to 0.4 V.

Capacitive Loading
Output valid and hold are based on standard capacitive loads: 30 pF on all pins (see Figure 36). The delay and hold specifications given should be derated by a drive strength related factor for loads other than the nominal value of 30 pF. Figure 37 through Figure 44 show how output rise time varies with capacitance. Figure 45 graphically shows how output valid varies with load capacitance. (Note that this graph or derating does not apply to output disable delays; see Output Disable Time on Page 37.) The graphs of Figure 37 through Figure 45 may not be linear outside the ranges shown.
