Abstract
Embodiments of the present invention are directed to a method and apparatus for hardware acceleration of clipping and graphical fill in display systems. In one embodiment, all display data is presented to the display system. The display system uses its hardware to clip the undesired data, if necessary, and display the desired data. If a sufficient amount of display data has the same value, the display system uses its hardware to fill the appropriate areas using the shared value. In one embodiment, the display system has one or more accelerating registers. In one embodiment, one or more accelerating registers are fill registers. As display data is read from memory, some of the information's color data is classified by the fill registers. In another embodiment, one or more accelerating registers are clipping registers. As display data arrives from each source, the information's display location is classified by the clipping registers.
