Computer system and method for controlling a processor thereof

Abstract

A computer system and a method for controlling a processor thereof are provided. A processor management unit (PMU) is programmed by the processor itself or by another processor according to a change of the operating condition of the processor. Then, a notification signal is sent to the PMU by the processor when the processor is entering a standby mode. Upon receiving the notification signal, the PMU adjusts the operating condition of the processor according to the change. Finally, a completion signal is sent by the PMU to the processor after the change of the operating condition of the processor is stabilized. Therefore, the unpredictable behavior caused by premature awakening of the processor during the adjustment of the operating condition can be avoided.

Dependencies are inferred from the claim text.
