摘要：
A multiprocessor system configured to share processes by a main system having a first processor and a subsystem having a second processor, comprises a first shared memory configured to receive accesses from the main system and the subsystem, a second memory configured to receive access from the subsystem at a power saving mode, a stop unit configured to stop accesses from the main system and the subsystem to the first shared memory when the subsystem enters the power saving mode, and a switching unit configured to switch an access destination of the subsystem from the first shared memory to the second memory when the subsystem enters the power saving mode.
