An electronic system includes a pipeline having a first number of pipeline stages coupled in series, a pipeline control unit, and a logic engine, wherein each pipeline stage in the pipeline is for outputting data to a next pipeline stage at each cycle of a clock signal. The pipeline control unit is for changing the first number of pipeline stages in the pipeline to a second number of pipeline stages. The logic engine is for performing operations of the electronic system in a first mode by utilizing the pipeline having the first number of pipeline stages and for performing operations of the electronic system in a second mode by utilizing the pipeline having the second number of pipeline stages. A frequency control unit and a voltage control unit, coupled to the pipeline and the logic engine, respectively adjust the frequency and voltage of the electronic system accordingly.

Electronic system and method for changing number of operation stages of a pipeline

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.
