The use of massively parallel associative processors as coprocessors for accelerating machine vision applications is considered. They achieve very fine granularity, as every word of memory functions as a simple processing element. A dense, dynamic, content-addressable memory cell supports fully parallel operation, and pitch-matched word logic improves arithmetic performance with minimal area cost. An asynchronous reconfigurable mesh network handles interprocessor communication and image input/output, and an area-efficient pass-transistor circuit counts and prioritizes responders. Some applications are discussed.
