Abstract
A method and apparatus for atomic frequency and voltage changes in the processor. In one embodiment of the invention, the atomic frequency and voltage changes in the processor is feasible due to the enabling technology of fully integrated voltage regulators (FIVR) that are integrated in the processor. FIVR allows independent configuration of each core in the processor and the configuration includes, but is not limited to, voltage setting, frequency setting, clock setting and other parameters that affects the power consumption of each core.
Claims21
