Abstract
An access violation of the program is monitored by the access monitor which is a hardware. The access monitor acquires a signal input from the CPU to a memory. The access monitor includes an access permission table as information of the memory region to be permitted to each program, and detects the access violation of the signal from the CPU by referring thereto. In this manner, the unjust access is monitored by the hardware, thereby preventing the unjust access by rewriting in software.
