  • DISTRIBUTED CHECKSUM COMPUTATION
    Publication number: 20120072812
    Abstract: Data is divided into parts and each part provided to a different processor. Each processor processes the provided data part to produce a partial CRC result. The partial CRC results from each of the different processors are XORed to produce a CRC of the data.

  • TWO DIMENSIONAL MEMORY ACCESS CONTROLLER
    Publication number: 20100214304
    Abstract: A data processing system may include a display, the display having a display surface, and logic to modify the address signals of a graphics processing unit (GPU) if the address signals do not fall within a two-dimensional range of authorized pixel locations corresponding to a subset of the display surface, and to propagate the address signals unmodified to a display memory otherwise.
