a complete platform with many features embedded system designs have some common elements: sensing, control, monitoring, and communication. there is no need for an engineer to spend time integrating all of those elements for every design. platform8051 offers a microprocessor and peripherals that include these common elements. the peripherals are optional elements of the platform; the designer just specifies which components are needed upon ordering. this platform saves the system integrator a significant amount of time. a fast core with built-in peripherals legacy 8-bit processors typically operate at only 12 mhz, 16 mhz, and 20 mhz. this is slow by today s standards. using actel fpgas and core8051, you can easily double your present processor performance without replacing legacy software code. core8051 performs at 45 mhz on actel s axcelerator devices and executes instructions in a single-cycle for most operation codes. core8051 is a fully functional 8-bit microprocessor intellectual property core that executes all asm51 instructions. the core has a robust set of internal peripherals that serve software and hardware interrupts, has an interface for serial communications and includes timers and power management. high performance peripherals platform8051 has many peripherals available to commu- nicate with the outside world. core10/100 is an ethernet media access controller that connects local area networks at data rates of 10 or 100 mb/s. it has a media independent interface (mii) for physical connection and implements carrier sense multiple access with collision detection (csma/cd) algorithms per ieee 802.3. ethernet is a common standard which is used in computer, communications, industrial, and other applications. core i2c is a bus controller which provides a two-wire serial interface that meets philips i 2 c specification. it can transmit or receive in master or slave mode and has a 7-bit addressing format with a fixed data width of 8-bits. it supports data transfers at 100 kb/s and 400 kb/s. i 2 c is a daisy-chained bus standard which is used in many consumer electronic and embedded applications. platform8051 actel core8051 block diagram fetch instr cycle fetch instr cycle timer_0_1 interrupt service ports power management memory control 8051 main engine core8051 control unit fetch instr cycle arithmetic logic unit serial channel clock control special function register bus ram_sfr control ram core8051 core sdlc core 10/100 platform8051 core 16x50 core i 2 c core spi optional rom base element apb platform8051 block diagram
corespi is a serial peripheral interface allowing high-speed synchronous serial data transfers between the 8051 and peripheral devices. this component supports full duplex operation with 8-bit serial data transfer and acts as a master or slave. spi is a point-to-point bus standard used in a variety of embedded applications. coresdlc is a high-speed synchronous serial data link controller. operation is similar to the intel 8xc152 global serial channel working in sdlc mode under cpu control. with axcelerator it supports data transfers greater than 17 mb/s. this core is useful for isdn, frame relay networks, and custom serial interfaces. core16x50 is a uart with or without fifo support and is used for asynchronous communication. it is 100% software compatible with the texas instruments 16550 device and capable of a baud rate greater than 10 mb/s on axcelerator devices. it adds additional serial channels to core8051. the 16x50 is useful as a serial or modem interface. fpga solution in addition to great ip cores and the world s best fpgas, actel provides a complete design solution. platform8051 includes core, testbench, documentation, and additional simulation files. the cores are available as rtl, netlist or evaluation versions. all code is compatible with standard synthesis and simulation tools as well as actel s popular libero tm and designer software offerings. microprocessor software development tools the popular 8051 instruction code is supported by a variety of software development tools. actel has partnered with two companies to provide an outstanding 8051 software code solution. a first silicon solutions (fs2) debugger and on-chip instrumentation (oci) code is included with each purchase of core8051 or the platform8051. the debugger includes four hardware execution breakpoints and unlimited software breakpoints. additional trigger and trace capability is available from fs2. keil software provides the pk51 for core8051, a complete integrated development environment (ide) which includes an instruction-accurate and cycle-accurate simulator as well as compiler, assembler, linker, and debugger. this ide is available free for a 30-day evaluation and it may be purchased for a very reasonable price from keil or fs2. platform8051 development kit the platform8051 development kit is all you need to get your 8051 design up and running immediately after purchase. it includes an apa600-fg676 evaluation board with a pre-programmed web-server demonstration design. the board includes off-chip memory, interface devices for the platform8051 peripherals, and a prototyping area for user communication. additionally, it includes the keil ide evaluation software, actel libero software, a universal power supply, a category 5 cable (for ethernet), an rs232 cable and an optional flashpro lite debug and jtag connector. core8051 ax250 77% apa150 74% rtsx72s 58% core10/100 ax500 56% apa300 81% rtsx72s 83% corei2c ax125 30% apa075 20% rtsx32s 22% corespi ax125 13% apa075 14% rtsx32s 10% coresdlc ax125 47% apa075 56% rtsx32s 33% core16x50 ax125 50% apa075 53% rtsx32s 37% example implementation axcelerator proasic plus rtsx-s device util. % device util. % device util. % platform8051 development board device utilization for platform8051 platform8051 actel
