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.
