Zusammenfassung:A method of regulating power consumption per core within a multi-core package may include estimating power draw for each core within the multi-core processing system. Estimating the power draw for each core within the multi-core processing system may include dividing a total power draw of the multi-core processing system by a number of active cores operating within the multi-core processing system multiplied by a percent utilization of the multi-core processing system. The method may include determining a thermal margin for the multi-core processing system, and instigating a lower power limit for the multi-core processing system in response to a determination that the thermal margin reduces to a predetermined level.
