Abstract
A system for caching texel information in a cache data store, for use in a graphics rendering system which uses interpolative sampling to compute texture color values. The system includes a texel memory storing texel information, a graphics application program for using interpolative sampling to compute dynamic texture values, a first cache data storage for a number of the most-recently-retrieved texels, a second cache data storage for a previously-retrieved adjacent line of texels, cache tag blocks for determining whether the texels needed by the graphics accelerator system are cached in either of the first or second cache data stores, and a memory request generator for retrieving texels from texel memory upon indication of a miss by the cache tag blocks.
