  • Data processing system having a pyramidal array of processors
    Patent number: 4622632
    Abstract: A pyramidal data processing system comprising a plurality of levels of processor arrays, the number of processors in an array increases in number from a level of lowest resolution to a level of highest resolution. Each processor in an array is coupled for data transfer to a neighborhood of processors including laterally and diagnoally adjacent processors in the same level, a processor in the level of next lowest resolution, and processors in the level of next greatest resolution. A memory is associated with each processor to store value of data elements. A controller and control memory generate control signals to perform in synchrony data transformations on selected data elements associated with each neighborhood of processors.
