  • Patent number: 8629880
    Abstract: A memory control device is adapted to derive a two dimensional location on a graphic display surface from address signals of a graphics processing unit (GPU), and to compare the derived two dimensional location to a two dimensional range of authorized locations corresponding to a subset of the display surface; and to modify the address signals of the graphics processing unit (GPU) if the address signals do not fall within the two-dimensional range of authorized locations corresponding to a subset of the display surface, and to propagate the address signals unmodified to a display memory otherwise.
    Type: Grant
    Filed: July 25, 2012
    Date of Patent: January 14, 2014
    Assignee: Presagis

  • Patent number: 8243088
    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.
