<p>A system which enables a change in the operating frequency and the power source voltage of a processor by the control of an operating system makes the operating frequency of a processor necessary to process a started periodical real-time task and non-real-time task without delays vary adaptively, and an optimal power source voltage for a processor determined according to the operating frequency switching time by time. This results in a reduction in power consumption by the processor while responding to with the real-time requests of application software.</p> |
