Design of an array processing unit for an array processor

An effort was made to design a small and cheap array processing unit (APU) to be used in a major distributed process array processor system for digital signal-processing applications. From the task definition and environment analysis, a design is presented. The unit, based on the Texas TMS 32020 and Intel 80186 is of the load-and-forget type and provides efficient memory management and operand accessing techniques to speed up the processing. An example is provided to illustrate details of the implementation and performance. It is concluded that the design presented fulfils requirements outlined for the APU.<>
