Note:
Description
The TSC695F (ERC32 Single-Chip) is a highly integrated, high-performance 32-bit RISC embedded processor implementing the SPARC architecture V7 specification. It has been developed with the support of the ESA (European Space Agency), and offers a full development environment for embedded space applications. The processor is manufactured using the Atmel 0.5 m radiation tolerant ( 300 KRADs (Si)) CMOS enhanced process (RTP). It has been specially designed for space, as it has on-chip concurrent transient and permanent error detection. The TSC695F includes an on-chip Integer Unit (IU), a Floating Point Unit (FPU), a Memory Controller and a DMA arbiter. For real-time applications, the TSC695F offers a high security watchdog, two timers, an interrupt controller, parallel and serial interfaces. Fault tolerance is supported using parity on internal/external buses and an EDAC on the external data bus. The design is highly testable with the support of an On-Chip Debugger (OCD), and a boundary scan through JTAG interface.

Product Description
Integer Unit
The Integer Unit (IU) is designed for highly dependable space and military applications, and includes support for error detection. The RISC architecture makes the creation of a processor that can execute instructions at a rate approaching one instruction per processor clock possible. To achieve that rate of execution, the IU employs a four-stage instruction pipeline that permits parallel execution of multiple instructions. * * Fetch - The processor outputs the instruction address to fetch the instruction. Decode - The instruction is placed in the instruction register and is decoded. The processor reads the operands from the register file and computes the next instruction address. Execute - The processor executes the instruction and saves the results in temporary registers. Pending traps are prioritized and internal traps are taken during this stage. Write - If no trap is taken, the processor writes the result to the destination register.
* *
All four stages operate in parallel, working on up to four different instructions at a time. A basic `single-cycle' instruction enters the pipeline and completes infour cycles. By the time it reaches the write stage, three more instructions have entered and are moving through the pipeline behind it. So, after the first four cycles, a single-cycle instruction exits the pipeline and a single-cycle instruction enters the pipeline on every cycle. Of course, a 'single-cycle' instruction actually takes four cycles to complete, but they are called single cycle because with this type of instruction the processor can complete one instruction per cycle after the initial four-cycle delay.
Floating-point Unit
The FLoating Point Unit (FPU) is designed to provide execution of single and doubleprecision floating-point instructions concurrently with execution of integer instructions by the IU. The FPU is compliant to the ANSI/IEEE-754 (1985) floating-point standard. The FPU is designed for highly dependable space and military applications, and includes support for concurrent error detection and testability. The FPU uses a four stage instruction pipeline consisting of fetch, decode, execute and write stages (F, D, E and W). The fetch unit captures instructions and their addresses from the data and address buses. The decode unit contains logic to decode the floatingpoint instruction opcodes. The execution unit handles all instruction execution. The execution unit includes a floating-point queue (FP queue), which contains stored floatingpoint operate (FPop) instructions under execution and their addresses. The execution unit controls the load unit, the store unit, and the datapath unit. The FPU depends upon the IU to access all addresses and control signals for memory access. Floating-point loads and stores are executed in conjunction with the IU, which provides addresses and control signals while the FPU supplies or stores the data. Instruction fetch for integer and floating-point instructions is provided by the IU. The FPU provides three types of registers: f registers, FSR, and the FP queue. The FSR is a 32-bit status and control register. It keeps track of rounding modes, floating-point trap types, queue status, condition codes, and various IEEE exception information. The floating-point queue contains the floating-point instruction currently under execution, along with its corresponding address.

Wait-state and Time-out Generator
It is possible to control the wait-state generation by programming a Wait-state Configuration Register. The maximum programmable number of wait-states is applied by default at reset. It is possible to program the number of wait-states for the following combinations: - - - - RAM read and write PROM read and write (i.e. EEPROM or Flash write) Exchange Memory read/write Four individual I/O peripherals read/write
A bus time-out function of 256 system clock cycles is provided for the bus ready controlled memory areas, i.e., the Extended PROM, Exchange Memory, Extended RAM,

Extended I/O and the Extended General areas. EDAC The TSC695F includes a 32-bit EDAC (Error Detection And Correction). Seven bits (CB[6:0]) are used as check bits over the data bus. The Data Bus Parity signal (DPAR) is used to check and generate the odd parity over the 32-bit data bus. This means that altogether 40 bits are used when the EDAC is enabled. The TSC695F EDAC uses a 7-bit Hamming code which detects any double bit error on the 40-bit bus as a non-correctable error. In addition, the EDAC detects all bits stuck-atone and stuck-at-zero failure for any nibble in the data word as a non-correctable error. Stuck-at-one and stuck-at-zero for all 32 bits of the data word is also detected as a noncorrectable error. Memory and I/O Parity The TSC695F handles parity towards memory and I/O in a special way. The processor can be programmed to use no parity, only parity or parity and EDAC protection towards memory and to use parity or no towards I/O. The signal used for the parity bit is DPAR. Programming the Memory Configuration Register, the TSC695F provides chip selects for two redundant memory banks for replacement of faulty banks. * * Unimplemented Areas - Access to all unimplemented memory areas are handled by the TSC695F and detected as illegal. RAM Write Access Protection - The TSC695F can be programmed to detect and mask write accesses in any part of the RAM. The protection scheme is enabled only for data area, not for the instruction area. The programmable write access protection is based on two segments. Boot PROM Write Protection - The TSC695F supports a qualified PROM write for an 8-bit wide PROM and/or for a 40-bit wide PROM.

DMA
DMA Interface The TSC695F supports Direct Memory Access (DMA). The DMA unit requests access to the processor bus by asserting the DMA request signal (DMAREQ). When the DMA unit receives the DMAGNT signal in response, the processor bus is granted. In case the processor is in the power-down mode the processor is permanent tri-stated, and a DMAREQ will directly give a DMAGNT. The TSC695F includes a DMA session time-out function. The TSC695F always has the lowest priority on the system bus. A trap is a vectored transfer of control to the supervisor through a special trap table that contains the first four instructions of each trap handler. The base address of the table is established by supervisor and the displacement, within the table, is determined by the trap type. Two categories of traps can appear.

It is possible to mask each individual interrupt (except Watchdog time-out). The interrupts in the Interrupt Pending Register are cleared automatically when the interrupt is acknowledged. By programming the Interrupt Shape Register, it is possible to define the external interrupts to either be active low or active high and to define the external interrupts to either be edge or level sensitive.

Timers
General Purpose Timer In software debug mode the timers are controlled by a system register bit and the external pin DEBUG. The General Purpose Timer (GPT) provides, in addition to a generalized counter function, a mechanism for setting the step size in which actual time counts are performed. GPT is clocked by the internal system clock. They are possible to program to be either of single-shot type or periodical type and in both cases generate an interrupt when the delay time has elapsed. The current value of the scaler and counter of the GPT can be read. Real Time Clock Timer The only functional differences between the two timers are that the Real Time Clock Timer (RTCT) has an 8-bit scaler (16-bit scaler for GPT) and that the RTCT interrupt has higher priority than the GPT interrupt. RTCT information is available on RTC output pin. Watchdog Timer Setting the external pin IWDE to VCC enables the internal watchdog timer. Otherwise the watchdog function must be externally provided. The watchdog is supplied from a separate external input (WDCLK). After reset, the timer is enabled and starts running with the maximum range. If the timer is not refreshed (reprogrammed) before the counter reaches zero value, an interrupt is sent. Simultaneo usly, the timer starts counting a reset time -out period. If the timer is not acknowledged before the reset time-out period elapses, a reset is applied to TSC695F.
UARTs
Two full duplex asynchronous receiver transmitters (UART) are included. In software debug mode the UART's are controlled by system register bits. The data format of the UART's is eight bits. It is possible to choose between even or odd parity, or no parity, and between one and two stop bits. The UART's provide double buffering, i.e. each UART consists of a transmitter holding register, a receiver holding register, a transmitter shift register, and a receiver shift register. Each of these registers are 8-bit wide. For each UART a RX and TX Register is provided. The UART's generate an interrupt each time a byte has been received or a byte has been sent. There is another interrupt to indicate errors. The baud rate of both the UART's is programmable. The clock is derived either from the system clock or can use the watchdog clock.
General Purpose Interface
The General Purpose Interface (GPI) is an 8-bit parallel I/O port. Each pin can be configured as an input or an output. A falling or rising edge detection is made on each selected GPI inputs. Every input transition on GPI generates an external positive pulse on GPIINT pin of two SYSCLK width.
Execution Modes
Reset Mode Reset mode is entered when: - - - - The SYSRES input is asserted Software reset which is caused by the software writing to a Software Reset Register Watchdog reset which is caused by a Watchdog counter time-out Error reset which is caused by a hardware parity error

This RESET output has a minimum of 1024 SYSCLK width to allow the usage of Flash memories. The error and Reset Status Register contain the source of the last processor reset. Run Mode In this mode the IU/FPU is executing, while all peripherals are running (if software enabled). System Halt mode is entered when the SYSHALT input is asserted. In this mode, the IU and FPU are frozen, while the timers (includeing the internal watchdog timer) and UART's are stopped. This mode is entered by writing to the Power-down Register. In this mode, the IU and FPU are frozen. The TSC695F leaves the power-down mode if an external interrupt is asserted. Error Halt mode is entered under the following circumstances: - - A internal hardware parity error. The IU enters error mode.
System Halt Mode
Power Down Mode
Error Halt Mode
The only way to exit Error Halt Mode is through Cold Reset by asserting SYSRESET.
Error Handler
The TSC695F has one error output signal (SYSERR) which indicates that an unmasked error has occurred. Any error signalled on the error inputs from the IU and the FPU is latched and reflected in the Error and Reset Status Register. By default, an error leads to a processor halt. The TSC695F includes: - - - - - Parity checking and generation (if required) on the external data bus Parity checking on the external address bus Parity checking on ASI and SIZE Parity checking and generation on all system registers Parity generation and checking on the internal control bus to the IU
Parity Checking
All external parity checking can be disabled using the NOPAR signal.
System Clock
The TSC695F uses CLK2 clock input directly and creates a system clock signal by dividing CLK2 by two. It drives SYSCLK pin with a nominal 50% duty cycle for the application. It is highly recommended that only SYSCLK rising edge is used as reference as far as possible. The SYSAV bit in the Error and Reset Status Register can be used by software to indicate system availability. The TSC695F includes a number of software test facilities such as EDAC test, Parity test, Interrupt test, Error test and a simple Test Access Port. These test functions are controlled using the Test Control Register.

Test Access Port
A variety of TSC695F test and diagnostic hardware functions, including boundary scan, internal scan, clock control and On-chip Debugger, are controlled through an IEEE 1149.1 (JTAG) standard Test Access Port (TAP). The TAP interfaces to the JTAG bus via 5 dedicated pins on the TSC695F chip. These pins are: * * * * * TCK (input): Test Clock TMS (input): Test Mode Select TDI (input): Test Data Input TDO (output): Test Data Output TRST (input): Test Reset
Instruction Register
Five standard instructions are supported by the TSC695F TAP.
