Abstract

A system and method for enabling a processor to access a memory not directly coupled to the processor. A memory request, including a request identifier field, is issued by a processor to a local memory management unit (MMU). Using the request identifier field, the local MMU determines whether the memory request should be issued by the local memory management unit (MMU) to a local memory, or should be transferred by the local MMU to a remote MMU and issued by the remote MMU to a remote memory, the remote memory associated with a different processor. In this manner, the remote MMU issues certain memory requests on behalf of the local processor and returns any results back to the local processor.
