  • System and method for implementing an overlay pathway
    Patent number: 5877741
    Abstract: A system and method for processing overlay display data. A display FIFO pipeline processes background graphics display data and a separate overlay FIFO pipeline processes overlay display data stored in an off-screen part of a graphics memory. The overlay FIFO pipeline performs format conversion, interpolation and scaling on the overlay display data and outputs it to an overlay mux. The overlay mux selects between the outputs of the display FIFO pipeline and the overlay FIFO pipeline in the processing of each scan line.
