  • System and method for fast gradient pixel clears in graphics rendering
    Patent number: 7466319
    Abstract: A system and method of maintaining a gradient in a plurality of pixels of a graphics display, such as a color or intensity gradient, where each pixel has an X coordinate, Y coordinate, and other pixel data that includes a fast-clear bit The pixels are filled on the display to create a gradient based upon the X or Y coordinates of the pixels, or a combination thereof, and when performing a pixel data operation, such as a read operation, the pixel data for a pixel with an activated fast-clear bit is ignored.
