Computer, recording medium was recorded address validity checking program, and address validity checking method

摘要

When the request processing means 2A receives the processing request associated with the memory access, the request processing means 2A executes the processing in accordance with the request and outputs an access request to the address designated by the processing request when the memory access occurs. The memory access substitution means 2B sets the memory protection information 1a of the object 1 to the memory management means 3a and outputs the memory access instruction to the processor 3. The memory management means 3A generates an exception when the memory access instruction from the memory access agency 2b is an access to a region other than the area set as the memory protection information 1a. Memory access performed by another object in response to an object request can be performed at high reliability and at high speed.
