Title: System and method for cache sharing

Abstract: A system and method for cache sharing. The system is a microprocessor comprising a processor core and a graphics engine, each coupled to a cache memory. The microprocessor also includes a driver to direct how the cache memory is shared by the processor core and the graphics engine. The method comprises receiving a memory request from a graphics application program and determining whether a cache memory that may be shared between a processor core and a cache memory is available to be shared. If the cache memory is available to be shared, a first portion of the cache memory is allocated to the processor core and a second portion of the cache memory is allocated to the graphics engine. The method and microprocessor may be included in a computing device.
