ABSTRACT:
A video display system includes a frame buffer includes five sets of one or more video random access memories. An address generator for generating address locations in the frame buffer generates ship select, row select and column select address signals. Because the frame buffer comprises five sets of video random access memories, the generation of the address signals requires divide-by-five operations to be carried out. Accordingly, the address generator includes a unique divide-by-five circuit wherein the division is carried out by a sequence of additions and multiplications. In comparison to conventional systems, the video system of the present invention makes more efficient use of memeory capacity in the frame buffer.
