  • Patent number: 6728863
    Abstract: A single-instruction multiple-data (SIMD) array processor providing enhanced data transfer efficiency. The SIMD array processor includes at least one memory and a plurality of mesh-connected processing elements configured in an array. Each processing element in the array includes at least one “narrow” memory buffer, at least one “wide” data register, and at least one “wide” communication register. The narrow memory buffer is adapted to transfer data serially between the memory and the wide data register, the wide data register is adapted to transfer data directly to the wide communication register, and the wide communication register is adapted to transfer data directly to the communication register of a neighboring processing element while the memory buffer is accessing data from the memory.

  • Patent number: 6487651
    Abstract: An SIMD array processor having a scalable and flexible architecture. The SIMD array architecture includes an array of processing elements, a plurality of processor controllers, and at least one other computer system. A system area network interconnects at least one user computer with the processor controllers and the computer system; and, a storage area network interconnects at least one storage device with the processor controllers and the computer system. The SIMD array architecture is adapted to allow different user computers to use different portions of the array of processing elements and/or different processor controllers and computer systems simultaneously. The array of processing elements has a hierarchical structure comprising backplanes, PCB's, ASIC's, and arrays of processing elements. The SIMD array architecture can be scaled by increasing the quantity of backplanes, PCB's, ASIC's, and/or by increasing the size of the arrays of processing elements.
