Abstract:
A multi-core processor system includes: a plurality of processor cores; a power supply unit that stops supplying or supplies power to each of the processor cores individually; and a thread queue that stores threads that the multi-core processor system causes the processor cores to execute. Each of the processor cores includes: a power-supply stopping unit that causes the power supply unit to stop power supply to an own processor core when a number of threads stored in the thread queue is equal to or smaller than a first threshold; and a power-supply resuming unit that causes the power supply unit to resume power supply to the other stopped processor cores when the number of threads stored in the thread queue exceeds a second value equal to or lager than the first threshold.
