A frame buffer system is disclosed that employs non overlapping serial enable signals to access pixel data values from sets of pixel buffers contained in each interleave of a multiple interleave frame buffer according to the attribute data in the frame buffer. The frame buffer system provides circuitry for varying the interleave factor between frame buffer accesses and the generation of corresponding video data. The frame buffer system also provides circuitry for expanding double buffered pixel data values into full addressing for color look-up.
