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 selective pixel data fillers for writing either X or Y position pixel data to the internal SRAM devices. By selectively storing either X or Y position pixel data, the graphics processor is able to perform bit-block data transfers (blts) of pixel data to the internal SRAM thereby efficiently utilizing the local bandwidth of the internal SRAM.
