Dynamic voltage control method and apparatus |
摘要 |
A dynamic power controller is provided that identifies a clock frequency requirement of a processor and determines a voltage requirement to support the clock frequency requirement. The dynamic power controller transitions the processor to a power state defined by the clock frequency requirement and the voltage requirement. In particular, a voltage level indicated by the voltage requirement is supplied to the processor and the frequency distribution indicated by the frequency requirement is provided to the clocks signals of the processor.
