Abstract
The information processing apparatus reserves a direct mapping region in the physical memory space and correlates physical addresses of the direct mapping region in the physical memory space with the virtual addresses of the virtual memory region in the virtual memory space of a process. Accordingly, the number of exception errors caused by the address translating unit is reduced, and the overhead on memory accesses is reduced.
