ABSTRACT:
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.
