A frame buffer including a memory array, circuitry for accessing the array, a plurality of latches each capable of storing a plurality of pixel values equivalent to a large portion of a row of pixels in the array which may be read simultaneously from the array, and circuitry for writing simultaneously to the memory cells of a row of the array the data stored in the latches whereby a row of pixels may be read and written back to the array bus in a minimum time period.

Method and apparatus for increasing the rate of scrolling in a frame

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.
