ABSTRACT:
A method and apparatus in a data processing system for performing a raster operation of graphics data. A system memory and a video memory is included in the data processing system. The system memory and the video memory are connected by a bus wherein the graphics data is organized into picture elements. A plurality of picture elements is read from the system memory. A plurality of picture elements is read from the video memory. A raster operation is performed on the plurality of picture elements to form a plurality of processed picture elements. The plurality of processed picture elements is written to the video memory.
