READABLE MEDIUM STORING INFORMATION PROCESSING PROGRAM, INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

摘要

PURPOSE: An information processing method for realizing an efficient access control about a shared memory is provided to maintain the completion of data by restricting access of the shared memory. CONSTITUTION: A part of virtual address space allocated to a first program matches with a physical address space according to the request of the first program(S1). In case an access restriction request of a share area is receipted by a second program, the validity of the access restriction request is adjudged(S9). An access to the shared memory by the first program is restricted in case the access restriction request is reasonable(S10).
