ABSTRACT:
Methods and systems are provided for dynamically managing the power consumption of a digital system. These methods and systems broadly provide for varying the frequency and voltage of one or more clocks of a digital system upon request by an entity of the digital system. An entity may request that the frequency of a clock of the processor of the digital system be changed. After the frequency is changed, the voltage point of the voltage regulator of the digital system is automatically changed to the lowest voltage point required for the new frequency if there is a single clock on the processor. If the processor is comprised of multiple processing cores with associated clocks, the frequency is changed to the lowest voltage point required by all frequencies of all clocks.
