A reconfigurable cache in a signal processor provides a cache optimized for texture mapping. In particular, the reconfigurable cache provides two-banks of memory during one mode of operation and a palettized map under a second mode of operation. In one implementation, the reconfigurable cache optimizes mip-mapping by assigning one texture map in one of the memory banks and a second texture map of a different resolution to the other memory bank. A special mapping pattern ("supertiling") between a graphical image to cache lines minimizes cache misses in texture mapping operations.
