The design and implementation of DSP TMS320C40 parallel processing system

This paper presents the design and implementation of four C40 based parallel processing system. It is comprised of four single CPU ISA-bus board. All four C40s are fully connected together through comports. The supporting software include basic tools such as simulator, assembler, linker, C compiler, parallel run-time support library. Four CPU debug/monitor software was also developed to ease programming. As an example, parallel FFT has been implemented using the system. Under the control of an IBM-PC, the system peak performance is 200 MFLOPS and can be further expanded. It is suitable for radar, sonar, image signal processing.
