ABSTRACT:
A method for optimizing a cache memory used for multitexturing in a graphics system is implemented. The graphics system comprises a texture memory, which stores texture data comprised in texture maps, coupled to a texture cache memory. Active texture maps for an individual primitive, for example a triangle, are identified, and the texture cache memory is divided into partitions. In one embodiment, the number of texture cache memory partitions equals the number of active texture maps. Each texture cache memory partition corresponds to a respective single active texture map, and is operated as a direct mapped cache for its corresponding respective single active texture map. In one embodiment, each texture cache memory partition is further operated as an associative cache for the texture data comprised in the partition's corresponding respective single active texture map. The cache memory is dynamically re-configured for each primitive.
