SHARED VIRTUAL MEMORY MANAGEMENT APPARATUS FOR SECURING CACHE-COHERENT

摘要

The present invention relates to a shared virtual memory management units for ensuring cache consistency, if more than one core is a single write access request to the virtual memory page simultaneously, in modification data after physical memory page is assigned in physical memory page, the data that cache coherency is a modification for ensuring the data consistency in multicore hardware environment are not provided after that only by original physical memory page is updated.
