Abstract
A device for storing pixel information for displaying a graphics image on a display includes a frame buffer and a processor. The information includes an intensity value and a value associated with each of a plurality of additional planes for each pixel. The frame buffer memory has a series of consecutive addresses for storing information to be output to the display. The frame buffer may be subdivided into a plurality of blocks, where each block corresponds to a region of the display having a plurality of contiguous pixels. The processor places the pixel information within the frame buffer memory so that in a given block there are placed at a first collection of consecutive addresses the intensity values for each of the pixels in the block.
