摘要： A technique to dynamically maintain the thermal levels of a plurality of cores of a processing system by interleave core hopping with throttling techniques. The interleaving logic may transfer execution of threads from a hot core to a cold if core hopping is applicable. Core hopping may be applicable if there exist a cold core to which the execution of threads can be assigned to from a hot core and if the rate of occurrence of core hopping is within an allowable rate value. The interleaving logic may apply throttling techniques if core hopping is not applicable. The throttling techniques may throttle the throttling parameters, which may comprise voltage, frequency, and micro-architecture throttling parameters provided to the hot core if the core hopping is not applicable.

摘要： Methods, apparatus, and articles of manufacture control a device or system that has an operational limit related to the rate or frequency of operation. The frequency of operation is controlled at a variable rate calculated to maximize the system or apparatus performance over a calculated period of time short enough that a controlling factor, such as power consumption, does not vary significantly during the period. Known system parameters, such as thermal resistance and capacitance of an integrated circuit (IC) and its package, and measured values, such as current junction temperature in an IC, are used to calculate a time-dependent frequency of operation for the upcoming time period that results in the best overall performance without exceeding the operational limit, such as the junction temperature.
