Abstract
A shared virtual memory management apparatus for ensuring cache coherence. When two or more cores request write permission to the same virtual memory page, the shared virtual memory management apparatus allocates a physical memory page for the cores to change data in the allocated physical memory page. Thereafter, changed data is updated in an original physical memory page, and accordingly it is feasible to achieve data coherence in a multi-core hardware environment that does not provide cache coherence.
