A method and apparatus within a processing environment is provided for proxy management of a plurality of proxy caches connected to a plurality of processing elements or cores within a unified memory environment. The proxy management system includes a proxy processor, such as a RISC core, that monitors data transfers or ownership transfers between the processing elements. If the proxy processor determines that a data transfer in one of the proxy caches will affect the coherency within another proxy cache, the proxy processor executes proxy management instructions such as invalidate, flush, prefetch to the appropriate proxy caches to insure coherency between the proxy caches and the unified memory.
