Abstract

A frame buffer for accelerating the display of graphics data on an output display device which frame buffer includes a pair of color value registers each of which may be loaded with color values prior to writing to the frame buffer. Selection means are provided for selecting pixel data from the bus, from a first of the color value registers, from the second of the color value registers, or from both color value registers simultaneously. When data is written to the frame buffer from color value registers it may be written to a number of pixel positions simultaneously.
