A multiple microcomputer system for digital signal and image processing applications is presented. A simple ring structure is employed to organize the multiple microcomputers. The data flow in the ring structure is unidirectional. A task can be partitioned and distributed among the microcomputers, making possible pipelined execution of a task. Implementation with the use of the TMS32010 signal processing CPU and IBM PC is demonstrated. A design to ensure the program synchronization is also shown. Algorithms for carrying out infinite impulse response filtering, the fast Fourier transform, and the McClellan transform method of 2-D finite impulse response filters are developed. Experimental results are presented.
