— Increasing demands for robust image recognition systems require vision processors not only with enormous computational capacities but also with sufficient flexibility to handle highly complicated recognition tasks. We describe a multi-SIMD architecture and the design of a vision processor based on it for carrying out such difficult image recognition tasks. The proposed architecture consists of two SIMD parallel processing modules and a shared memory, allowing highly parallelized and flexible computation of complicated recognition tasks, which were difficult to process on a conventional massively parallel SIMD architecture. We designed a prototype vision processor for evaluation purposes and confirmed that the processor could be implemented in FPGA.
