    Abstract: A graphics system includes a graphics processor for rendering graphics primitives with a list of display parameters. A host processor generates a display list which includes a XY address for rendering the graphics primitives. A graphics processor which includes internal fetch and store static random access memory (SRAM)devices for storing pixel fetched from an external memory device and processed in the graphics processor respectively. The graphics processor also includes a pixel data striping control logic which determines whether fetch and store requests by the graphics processor crosses an X boundary in the internal SRAM devices. If a fetch or store request crosses an X boundary, the memory control logic stripes the access into separate blocks of pixel data for each access which are then simultaneously accessed during a single data request cycle.
