Patent ID: 8732495

Claim:
A system for dynamic frequency and voltage control, the system comprising: a processor voltage regulator configured to provide a core voltage signal to a processor, and further configured to detect a present processor load state of the processor; a system clock generator directly coupled with the processor voltage regulator through a communication interface, the system clock generator configured to: provide a system clock signal to the processor; provide the system clock signal to peripheral devices of the system; and provide at least one voltage signal to the peripheral devices of the system; wherein at least one of the processor voltage regulator or the system clock generator is configured to: determine a desired frequency of the system clock signal responsive to the present processor load state; determine a voltage level for the core voltage signal suitably paired with the desired frequency for operation of the processor at the desired frequency; and communicate an indicator of at least one of the desired frequency or the voltage level over the communication interface between the processor voltage regulator and the system clock generator; and wherein the system clock generator is further configured to change the at least one voltage signal provided to the peripheral devices of the system responsive to the present processor load state.
