Method and apparatus for atomic frequency and voltage changes

摘要

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.

主权项

1. A processor comprising:
a plurality of voltage regulators; a plurality of clock generators; and a plurality of cores, wherein each core is coupled to one of the plurality of voltage regulators and one of the plurality of clock generators, and wherein at least one core is to perform an atomic ratio change of the corresponding clock generator responsive to a request to change a frequency of the at least one core.
