Abstract
When a request processing unit 2a receives processing request including memory access, it executes processing in accordance with the request, and when memory access takes place, it outputs access request to address designated by the processing request. A memory access proxy unit 2b sets memory protection information 1a of object 1 at a memory management unit 3a to output memory access instruction to a processor 3. The memory management unit 3a generates exception when memory access instruction from the memory access proxy unit 2b is access except for area set as memory protection information 1a. Thus, it is possible to carry out, at high speed, with high reliability, memory access such that, in accordance with request of an object, other object executes.
