The AIS-5000 parallel processor

The AIS-5000 is a commercially available massively parallel processor which was designed to operate in an industrial environment. It has fine-grained parallelism with up to 1024 processing elements arranged in a single-instruction multiple-data (SIMD) architecture. The processing elements are arranged in a one-dimensional chain that, for computer vision applications, can be as wide as the image itself. The overall architecture of the system is described. Various components of the system are discussed, including details of the processing elements, data I/O (input/output) pathways and parallel memory organization. A virtual two-dimensional model for programming image-based algorithms for the system is also presented. Performance benchmarks are given for certain simple and complex functions.<
