PROBLEM TO BE SOLVED: To provide a method and a system to accelerate address conversion from a virtual address to a physical address by mapping a virtual memory area by a large page according to a use situation of a virtual memory and individually processing a physical page corresponding to a virtual page needing individual coping inside the virtual memory area mapped to the large page. SOLUTION: In this method to accelerate the address conversion to the physical address, a computer maps the virtual memory area including a plurality of virtual pages each having a page unit satisfying a prescribed condition by the large page that is an area larger than the virtual page, and sets physical memory protection information for protecting the physical page corresponding to a part of the virtual pages wherein a memory protection attribute differs on condition that the memory protection attribute of the part of the virtual pages included in the mapping large page differs from a memory protection attribute of the other virtual pages.
