PROVIDING HARDWARE SUPPORT FOR VIRTUAL MEMORY SHARED BETWEEN LOCAL PHYSICAL MEMORY AND REMOTE PHYSICAL MEMORY

摘要

PROBLEM TO BE SOLVED: To provide hardware support for virtual memory shared between local physical memory and remote physical memory.SOLUTION: A method comprises: receiving a memory access request including a virtual address; analyzing an entry corresponding to the virtual address stored in a translation lookaside buffer (TLB) of a processor in order 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 coupled to the processor via a non-coherent link; and if the PA is present in the remote memory, sending a reverse proxy execution request to the remote memory in order to perform the memory access request. The local memory and the remote memory collectively form a shared virtual memory space.
