Abstract
Interprocessor communications has always been a performance bottleneck in bus-oriented multiprocessor systems. A two-dimensional array (mesh) of simple processors operating in the SIMD mode has been found very suitable for low-level image processing. Degradation in the throughput of mesh-type multiprocessor systems due to interprocessor communications has been determined. It is observed that the ratio of inter-processor communications to the actual computation increases with an increase in the number of processors. Concurrent processing with overlapped inter-processor communication has been shown to significantly reduce the degradation, and has been illustrated in the case of a low-level image processing algorithm on a 2-dimensional array of processors having dedicated inter-processor links.
