TRILINEAR TEXTURE FILTERING WITH OPTIMIZED MEMORY ACCESS

摘要

A trilinear texture filtering system (800) and method that improves the locality of texture map accesses in a multum in parvo (MIP) map so as to reduce page breaks and provide improved performance. The present invention includes a texture cache (804) having a unique addressing and accessing scheme that allows localized reads of the texture map from each of four banks in the texture cache (804). This is coupled with a unique texture-mapping unit (806) that includes a first level generator, a second level generator, and an interpolator.
