Abstract: An information processing apparatus has a CPU, a clock supply unit configured to supply a clock signal, a CPU idle ratio obtaining unit configured to obtain the idle ratio of the CPU at each predetermined time, a clock control unit configured to determine an operating frequency of the clock signal, and a DMA transfer unit configured to execute a DMA transfer in synchronization with the clock signal supplied from the clock supply unit. The clock control unit controls the operating frequency of the clock signal to the operating frequency determined based on the idle ratio of the CPU if the DMA transfer is not being executed, whereas the clock control unit controls the operating frequency of the clock signal to a predetermined frequency if the DMA transfer is being executed.
