Claim:
1. A method comprising: providing a processor comprising: providing a first voltage regulator to generate a first operational voltage coupled to the first power domain; providing a second voltage regulator to generate a second operational voltage coupled to the second power domain; controlling the first voltage regulator with one or more voltage controllers; and controlling the second voltage regulator with the one or more voltage controllers, the controlling the first voltage regulator and the second voltage regulator comprising setting the second operational voltage to a second voltage level lower than the first operational voltage from a first voltage level equal to the first operational voltage, wherein the one or more voltage controllers and the core block are configured to determine the first operational voltage and the second operational voltage, and the first voltage regulator and the second voltage regulator are in a same die as the core block.
