Abstract This paper discusses the design of a simple multimicroprocessor system to be built into the dedicated instrument, and also discusses the design for the system. The 8‐bit processor sometimes makes it difficult to realize the required function or necessitates a sophisticated technique or experience to realize the function. However, this paper demonstrates that there exist techniques that can easily be incorporated into the processor in the system to realize the required function and performance. The hardware discussed in this paper is flexible so that the result of functional analysis can be realized directly as the structure. The problems of parallel processing that will inevitably arise in this kind of approach are then solved by queue and synchronized registers. Hence, the hardware structure (number and connections of processors and memories) is determined according to the result of structured programming, and parallel processing programs are designed to be performed along the lines of the past single‐stream system. The performance of the system can be modified by modifying the number of processors and the hardware structure without completely changing the program, only by reassignment of the memory. From the practical viewpoint, 80‐type CPU (Intel 8085A), most widely used at present, is adopted. The result of experimental set‐up and simple application examples are shown.
