Abstract

Increasing acceptance of the necessity for high-order parallelism in order to progress digital processing still leaves open the large question of what machine architectures are best for which class of problem. To help answer this, we are investigating and comparing the use of both SIMD and MIMD architectures for programmable processing in real-time systems. A distributed array machine, Mil-DAP (derived from the original ICL DAP) has been developed and benchmarked on radar, image processing, and on terrain modelling problems. Multi-transputer arrays have been applied to an overlapping set of problems in image processing, FFT and terrain-based computation. The results are compared and preliminary conclusions drawn.
