GPU Method for caching GPU data and data processing system therefore

摘要

The present invention discloses a multimedia data processing system and thus a selective caching method. The selective caching method in such a multimedia data processing system includes inserting cacheability indicator information into an address translation table descriptor that is memory allocated for graphics resources when it is determined that the graphics resources need to be cached. In addition, it includes the step of selectively controlling whether to cache the multimedia data in the system level cache memory by referring to the cacheability indicator information in the address translation operation mode of the GPU.
