<p>PROBLEM TO BE SOLVED: To provide a computer system with which a CPU power saving function or a CPU clock switching function is more efficiently operated by controlling a timer interruption interval. SOLUTION: When the idle state of a system is detected, a monitor system 101 to be periodically called for monitoring the operating conditions of the system acquires an availability rate of a CPU 11 and reloads a register 131 of a system controller 13. Thus, a timer interruption interval is set corresponding to the acquired availability rate of the CPU 11, and the supply of a clock to the CPU 11 is stopped by estimating that the supply of the clock to the CPU 11 in a stop state is restarted with a timer interruption. Namely, the timer interruption is appropriately controlled so that the longer the idle state lasts, for example, the larger the interval to generate the timer interruption is set.</p> |
