Abstract: An apparatus is provided. The apparatus includes a plurality of counters configured to count electrical activity switching events of cores, a first circuit configured to predict a temperature at a location based on counts of at least one of the plurality of counters, and a second circuit configured to schedule a thermal mitigation function based on the predicted temperature. A method for scheduling thermal mitigation functions is provided. The method includes counting electrical activity switching events, predicting a temperature at a location based on the counting of the electrical activity switching events, and scheduling a thermal mitigation function based on the predicted temperature. Another apparatus is provided. The apparatus includes means for counting electrical activity switching events, means for predicting a temperature at a location based on a count of the electrical activity switching events, and means for scheduling a thermal mitigation function based on the predicted temperature.

Abstract: An apparatus and a method to adjust a source voltage based on an operating voltage response are provided. The apparatus includes a circuit configured to change state from a first state to a second state comprising receiving an operating voltage from a power source through a power distribution network. The apparatus further includes a sensor configured to measure an operating voltage response to the circuit changing state to receiving the operating voltage. The apparatus further includes a control circuit configured to adjust a source voltage at the power source based on the operating voltage response measured by the sensor. The method includes changing a state to receiving an operating voltage from a power source through a power distribution network, measuring an operating voltage response to the changing state to receiving the operating voltage, and adjusting the source voltage at the power source based on the measured operating voltage response.
