PROBLEM TO BE SOLVED: To provide hardware support for shared virtual memory between local physical memory and remote physical memory.SOLUTION: Upon receiving a memory access request including a virtual address, an entry is analyzed corresponding to the virtual address stored in a translation lookaside buffer (TLB) of a processor (CPU) 120 to determine if a physical address (PA) corresponding to the virtual address is present in a local memory associated with the processor or a remote memory associated with an accelerator 150 coupled to the processor via a non-coherent link. If the PA is present in the remote memory, a reverse proxy execution request is sent to the remote memory to perform the memory access request. The local memory and the remote memory collectively form a shared virtual memory space. |
