First Claim
Patent Images
1. A method comprising:
- mapping pixels of a first frame of a video stream to texels;
selecting a subset of the texels for shading based on previously cached texels that were shaded for a second frame;
shading the subset of the texels;
caching the shaded subset of the texels with the previously cached texels; and
determining values for the pixels of the first frame based on the cached texels.

Abstract
A graphics processing unit is configured to map pixels of a first frame of a video stream to texels, select a subset of the texels for shading based on previously cached texels that were shaded for a second frame, and shade the subset of the texels. The graphics processing unit is also configured to cache the shaded subset of the texels with the previously cached texels and determine values for the pixels of the first frame based on the cached texels.

10. An apparatus comprising:
-
a processing unit to map pixels of a first frame of a video stream to texels, select a subset of the texels for shading based on previously cached texels that were shaded for a second frame, and shade the subset of the texels; and a memory to cache the shaded subset of the texels with the previously cached texels, wherein the processing unit is to determine values for the pixels of the first frame based on the cached texels. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
