  • Patent number: 6657635
    Abstract: Methods and systems for optimizing graphics data processing employ various binning flush algorithms to optimize the utilization of binning memory in a graphics system. Binning flush algorithms provide for processing all geometry and commands binned up to the point the binning memory becomes unavailable, and storing and restoring all necessary intermediate data generated during the partial tile rendering.

  • Patent number: 6614448
    Abstract: A graphics processor displays pixels in an image at non-uniform resolution, using a maximum resolution in the interior of a surface in the image, and a lower resolution at edges. Higher color resolution in the interior eliminates color aliasing that would otherwise be caused if the interior were displayed at the lower resolution. Lower resolution at the edges is not noticeable to the human eye, and allows the graphics processor to use one or more low resolution color signals in generating the displayed image, thereby reducing hardware (e.g. memory locations required to store such signals, and lines required to route such signals). One such processor (not necessarily a graphics processor) includes a resolution reducer and a resolution enhancer that respectively reduce and enhance the resolution of a signal. Specifically, the resolution reducer reduces the resolution of a high resolution signal to generate a low resolution signal.
