  • Patent number: 5842034
    Abstract: A parallel processor array with a two-dimensional crossbar switch architecture. Individual processing elements are configured as clusters of processors, wherein the individual processing elements within each cluster are interconnected by a two dimensional cluster network of crossbar switch elements. The clusters are interconnected via a two dimensional array network of crossbar switch elements, supporting high-bandwidth inter-processor data shuffles that characterize parallel implementations of sensor processing problems. Input data is supplied directly into the array network of crossbar switch elements, which allows an optimal initial partitioning of the data set among the processing elements. The array architecture supports a virtual array sizing, where the processor array can be treated as a variable sized array with dimensions that are software controllable, selectable to match system characteristics.

  • Patent number: 5630154
    Abstract: A linear systolic array of computation cells, each cell having several vector rotation stages. These stages are programmable to provide efficient implementation of a variety of matrix algorithms. All data movement between cells is via parameterized data packets, and the full linear systolic array is completely data flow driven at the packet level. Physical computation cells can be mapped to act as one or more logical computation cells, allowing a small array to function logically as a larger array through a logical folding. This mapping also allows defective cells to be bypassed for fault tolerance. The array can be used to compute adaptive weights in digital beamforming radar applications.
