Abstract
A pixel color processor that performs supplemental graphical processing duties in a video unit in a computer system. The pixel color processor is interfaced between a processor and video memory and performs pixel string manipulation and color management duties on the pixel color data at the direction of the processor, thereby freeing up the processor of these duties. The memory address space of the processor includes a monochrome memory area which maps onto the full-depth packed-pixel video memory. When the processor performs operations on this monochrome area, the pixel color processor intercepts the addresses data generated by the processor and performs the pixel block transfers.
