Abstract
An improved raster engine adapted to render video data from a frame buffer to one of a plurality of disparate displays is disclosed which comprises an integral bounded video signature analyzer, a hardware cursor apparatus supporting dual scanned displays, programmatic support for multiple disparate display types, multi-mode programmable hardware blinking, programmable multiple color depth digital display interface, and programmable matrix controlled grayscale generation.
Claims28
A video controller for interfacing a frame buffer to a display in a computer system, comprising:
- a raster engine adapted to receive video data from the frame buffer, to format the video data, and to render the formatted data to the display;
- and
- a hardware blink logic system operatively associated with the raster engine to selectively blink at least one pixel on the display;
- wherein formatting the video data comprises selectively remapping the video data to a format appropriate for interfacing with a selected one of a plurality of display device types.
In a video controller, a method of interfacing a frame buffer to a display in a computer system, comprising:
- providing a raster engine adapted to receive video data from the frame buffer, to format and selectively remap the video data, and to render the formatted and selectively remapped data to the display;
- and
- selectively blinking at least one pixel on the display using a hardware blink logic system operatively associated with the raster engine.
