ABSTRACT:
Provided is a multiprocessor control apparatus that restrains impairment of processing speed of entire operations, while pursuing power consumption saving for a multiprocessor. The multiprocessor control apparatus has: an execution control unit operable to control a processor to, when processors other than the processor have ended respective operations performed in parallel, start performing an operation that uses a result of the operations; and a power control unit operable to control power supply to the processor, where when the processor has been under power-supply restriction, the power control unit cancels the power-supply restriction before one of the other processors, which is the last of all the other processors to end a corresponding operation, ends the corresponding operation.
