Abstract

An apparatus for managing the temperature of an integrated circuit having a multiple core microprocessor is described. Specifically, thermal sensors are placed at potential hot spots throughout each microprocessor core. A thermal management unit monitors the thermal sensors. If a thermal sensor identifies a hot spot, the thermal management unit adjusts the operating frequency and voltage of that microprocessor core accordingly.
