Abstract: A method and apparatus for graphic processing using multi-threading includes at least one context task, mediation task, and control task executed by a processor. The at least one context task sequentially generates graphic commands. The mediation task mediates processing of the graphic commands. The mediation task may process a particular graphic command on behalf of the at least one context task, and change a processing order of the graphic commands. The control task transmits the graphic commands to a graphic hardware.

Abstract: A method and apparatus for providing shared caches. A cache memory system may be operated in a first mode or a second mode. When the cache memory system is operated in the first mode, a first cache and a second cache of the cache memory system may be operated independently. When the cache memory system is operated in the second mode, the first cache and the second cache may be shared. In the second mode, at least one bit may overlap tag bits and set index bits among bits of a memory address.

Abstract: A cache memory system and a caching method for a tile-based rendering may be provided. Each of cache lines in the cache memory system may include delayed-replacement information. The delayed-replacement information may indicate whether texture data referred to at a position of an edge of a tile is included in a cache line. When a cache line corresponding to an access-requested address is absent in the cache memory system, the cache memory system may select and remove a cache line to be removed from an associative cache unit, based on delayed-replacement information.
