IMPLEMENTING A TMS320C2X-BASED DUAL PROCESSOR DSP BOARD

DSP education is established in the standard curriculum of most electrical engineering departments around the world. Since theoretical study is more or less standardized, we looked for ways to involve students in practical design projects. The TI DSP Solutions Challenge gave us the opportunity to study, design, and implement a DSP system of moderate to high complexity.

We chose the Texas Instruments (TI(TM)) fixed point TMS320C2x family because of its high flexibility, wide availability, and the fact that many industrial systems are based on it. Furthermore, most real-time DSP processing in speech/audio, communication, and imaging uses this device. We selected a parallel dual-processor shared memory architecture because it reinforces parallel processing concepts and offers a flexible and powerful research and development tool to solve real problems.

This paper describes the general design of the system and its features as well as the analog I/O, which is standard but is the link for most real world experiments. Detailed PAL listings, some of them with simulation parts and schematics are included and referred to throughout the text. In addition, PCB designs were provided in PCAD format on disks accompanying the text. The board was manufactured as a 6 layer PCB thanks to the help given to us by GATO, a Bulgarian technical consultant firm.
