ABSTRACT:
A system and method for conserving memory bandwidth while supporting multiple sprites includes a memory device that stores main display data and the multiple sprites for presentation upon a display device. A display controller populates a fetch table with pixel source identifiers that indicate pixel sources from either the main display data or one of the multiple sprites. The pixel source identifiers correspond to display pixels of the display device. The display controller then utilizes the pixel source identifiers to directly locate the appropriate display pixels from the various pixel sources for providing to the display device.
