    摘要: A method for dynamically operating a multi-core processor system is provided. The method involves ascertaining currently active processor cores, identifying a currently active processor core having a lowest operating frequency, and adjusting at least one operational parameter according to voltage-frequency characteristics corresponding to the identified processor core to fulfill a predefined functional mode, e.g. power optimization mode, performance optimization mode and mixed mode.

    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.

    摘要: The operating rate of an electronic system is maximized without exceeding a thermal constraint, such as a maximum junction temperature of an integrated circuit (IC) or other portion of the electronic system. An operating parameter of the system that controls the thermal output of the system is calculated for an upcoming time period based upon the previously measured thermal performance relationship to the operating parameter level. If the predicted thermal performance will exceed a maximum allowable level of the thermal constraint, then the operating parameter is reduced by an amount calculated to keep the thermal constraint at a level just below the maximum allowable level, thus resulting in an optimal control approach to maximizing the system performance while not exceeding the thermal constraint.
