Abstract
An information processing system includes a CPU that is connected to a bus; a device that is connected to the bus; a memory that is accessed by the CPU or the device; and a power mode control circuit that sets a power consumption mode. The power mode control circuit sets the power consumption mode based on first information that indicates a cache hit or a cache miss of a cache memory in the CPU and second information that indicates an activated state or a non-activated state of the device.
