The processing of digitized infrared images in real time requires more processing power than usually provided by a single sequential processor. A system of tightly-coupled 16 bit microcomputers (INTEL 8612) is being developed to provide the needed computational capa-city. This paper first describes an image processing program for detection of moving targets in infrared images. It then describes how several microcomputers on a system bus form a cluster and how a complete star bus switch network permits memory references between clusters. The operating system allocates code and data segments to memory in order to minimize bus contention. Several computational processes are multiprogrammed on each microcomputer. Criteria for partitioning the algorithms into explicit processes and segments is discussed.
