Abstract
The current invention involves new systems and methods for reorganizing a texture sampling order that is used to read texels from a texel cache. When anisotropic filtering is used to process the texels read from the texel cache, the texels are read in an order based on a major axis alignment. Reorganizing texture sampling order to use the order based on the major axis alignment results in improved texel cache locality, thereby improving texel cache performance.
