Abstract:
An apparatus includes: a memory; a management memory for storing first virtual addresses used by the first program, second virtual addresses used by the second program and management information indicative of association between first and second virtual addresses and physical addresses of the memory; and a processor for executing the first, the second and a management programs, the management program including: receiving a request to assign a shared area to be shared by the first and second programs from the second program; determining a physical address of the shared area corresponding to one of the first and one of the second virtual addresses; transmitting a notification of data writing by the first program to the second program; locking the shared area so as to prevent the second program from writing data after the notification; and unlocking the shared area after the second program has read data from the shared area.
