Abstract:
In an embodiment, a processor includes voltage calculation logic to calculate a plurality of maximum operating voltage values each associated with a number of active cores of the plurality of cores, based at least in part on a plurality of coefficient values. In this way, the processor can operate at different maximum operating voltages dependent on the number of active cores. Other embodiments are described and claimed.
