Abstract:
Methods, software, and apparatuses for graphics processing, including caching pixel data of one or more tiles of a graphics surface. Methods generally include setting a caching bit corresponding to the surface, setting tile pattern bits corresponding to tiles in the surface, and when the caching bit is active, storing one or more pixel values in a cache memory. When at least one tile contains pixels having the same value for at least one predetermined parameter, the caching bit and the corresponding tile pattern bits may be active. Apparatuses generally include a pixel memory, a cache memory, and a controller including logic configured to reserve the caching bit, tile pattern bits, and same pixel values in cache memory when the caching bit is active.
