Abstract: Provided are a multimedia data processing system and a selective caching method. The selective caching method in the multimedia data processing system includes inserting cacheability indicator information into an address translation table descriptor undergoing memory allocation to a graphics resource when the graphics resource needs to be cached and selectively controlling whether or not to prefetch multimedia data of the graphics resource present in a main memory to a system level cache memory, with reference to cacheability indicator information during an address translation operation of a graphic processing unit (GPU). The inventive concept can be implemented in a wide variety of computer-based systems having a graphical output, such as cell phones, laptops, tablets, and personal computers, as only a few examples.

Abstract: A multimedia data processing method is provided which includes providing a conflict detection unit at a load/store pipeline unit; generating, by the conflict detection unit, speculative conflict information, which is used to predictively determine whether an address of a load/store instruction of a current thread causes a conflict miss before a cache access operation is performed by performing a history search for load/store instruction addresses of previous threads without referring to a cache memory; and storing information of the current thread directly in a standby buffer without an execution of the cache access operation in response to the generated speculative conflict information indicating the conflict miss.
