The EZ-DSP CPU-52 provides a low cost method for debugging and evaluating the TMS320BC52 Texas Instruments microprocessor. The 'C52's advanced Harvard type architecture maximizes the processing power by maintaining two separate memory bus structures, program and data, for full-speed execution. Instructions support data transfers between the two spaces. This architecture permits coefficients stored in program memory to be read into the RAM, eliminating the need for a separate coefficient ROM. It also makes available immediate instructions and subroutines based on computed values. Control signals and instructions provide floating-point support, block memory transfers, communication to slower off-chip devices and multiprocessing implementations.

The EZ-DSP Manager software is used to communicate (through a host computer or terminal's serial port) with the EZ-DSP CPU-52 Single Board Computer. The EZ-DSP Manager software allows you to modify and display on-board user data/program memory, disassemble program memory (to the screen or dump to a file), assemble source code and download corresponding hex files, execute user programs, set breakpoints and display "watch" variables, modify and display CPU register contents and display the contents of user memory "graphically" on the screen.

The EZ-DSP Manager allows you to appreciate the features and the ease of operation of using this "menu driven" monitor program. Unlike other "monitor" programs that require you to memorize and type numerous commands, the EZ-DSP Manager software has all of the commands listed for you in categorized pull down menus.

• In order to run the EZ-DSP Manager software, the following system is required:
• IBM Personal Computer (or compatible)
• MS-DOS (version 3.0 or later)
• Minimum 640K RAM memory
• EGA or VGA graphics adapter card
• RS-232 serial interface port
• A mouse is suggested but is not required
• A hard disk is suggested but is not required

• TMS320BC52 CPU in a 100 pin thin quad flat package.
• 25-, 35- and 50-ns Single-Cycle Instruction execution time with 3-V or 5-V operation.
• Single-Cycle 16 x 16-Bit Multiply/Add.
• 128K Words total Data/Program space.
• 4K x 16-Bit Single access on-chip program ROM.
• 1K x 16-Bit Dual access on-chip program/data ROM.
• Full-Duplex synchronous serial port for CODEC interface.
• Hardware or software wait state generation.
• On-chip timer for control operations.
• Repeat instructions for efficient use of program space.
• Multiply-by-two and divide-by-two clocking options.
• Block moves for data/program management.
• On-chip scan based emulation logic.
• Low power dissipation and power down modes:
•  
  • 47mA (2.35 mA/MIP) at 5V, 40-MHz
  • 3 mA at 5V, 40-MHz (typical IDLE2)
  • 5 uA at 5V, clocks off (typical standby)
