PASM: A Reconfigurable Multimicrocomputer System for Image Processing.
Abstract
As a result of the microprocessor revolution, it is now feasible to build multimicroprocessor systems capable of performing image processing tasks more rapidly than previously possible. There are several types of parallel processing systems. An SIMD (single instruction stream - multiple data stream) machine typically consists of a set of N processors, N memories, an interconnection network, and a control unit (e.g. Illiac IV). The control unit broadcasts instructions to the processors and all active ('turned on') processors execute the same instruction at the same time. Each processor executes instructions using data taken from a memory with which only it is associated. The interconnection network allows interprocessor communication. An MSIMD (multiple-SIMD) systems is a parallel processing system which can be structured as two or more independent SIMD machines (e.g. MAP). An MIMD (multiple instruction stream - multiple data stream machine typically consists of N processors and N memories, where each processor can follow an independent instruction stream (e.g. C.mmp). As with SIMD architectures, there is a multiple data stream and an interconnection network. A partitionable SIMD/MIMD system is a parallel processing system which can be structured as two or more independent SIMD and/or MIMD machines.
