Abstract
According to one embodiment, a state manager classifies an area allocated to the multi-core processor in a first memory area into one of a first state in which allocation to processor cores is not performed, a second state in which allocation to one of the processor cores is performed and read and write are performed, and a third state in which allocation to one or more of the processor cores is performed and read and write are prohibited, and further performs a transition from one of the first state, the second state, and the third state to another. A cache/memory manager writes back a corresponding cache when the state manager performs the transition from the second state to the third state.
