A PARALLEL ARRAY OF MICROPROCESSORS- AN ALTERNATIVE SOLUTION TO DIFFUSION PROBLEMS

This paper explores the possibility of using a parallel, special-purpose-processor to solve diffusion problems. The system considered in an N-Dimensional Array of Microprocessors each of which provides an explicit solution of the diffusion eq-uation at its own location. A master-slave arch-itecture is used in which it has been demonstrated that private memory assignment offers a consider-able advantage over a common memory array in terms of complexity and the tradeoff between interpro-cessor interference and memory reduction. For eco-nomic reasons all communication in the prototype is by means of serial links. communication protocol is very specific with th
