Abstract
In an embodiment, a processor includes a plurality of cores and a plurality of temperature sensors, where each core is proximate to at least one temperature sensor. The processor also includes a power control unit (PCU) including temperature logic to receive temperature data that includes a corresponding temperature value from each of the temperature sensors. Responsive to an indication that a highest temperature value of the temperature data exceeds a threshold, the temperature logic is to adjust a plurality of domain frequencies according to a determined policy that is based on instruction execution characteristics of at least two of the plurality of cores. Each domain frequency is associated with a corresponding domain that includes at least one of the plurality of cores and each domain frequency is independently adjustable. Other embodiments are described and claimed.
