    (54) Pipeline architecture for generating video signal


    (57) A symbol generator with pipeline architecture comprised of a series of processing stages that regenerate a complete video data signal for each display field is disclosed herein. The pipeline design offers a number of advantages over other systems. Any symbol in a display may be moved in real time and independently of any other symbol, because the display is regenerated for each and every field. The symbol generator includes a cpu microprocessor, vertical sorter, boundary generator, horizontal sorter, and color palette.
