    • A method and system for determining an energy-efficient operating point of the platform or system. The platform has logic to dynamically manage setting(s) of the processing cores and/or platform components in the platform to achieve maximum system energy efficiency. By using the characteristics of the workload and/or platform to determine the optimum settings of the platform, the logic of the platform facilitates performance guarantees of the platform while minimizing the energy consumption of the processor core and/or platform. The logic of the platform identifies opportunities to run the processing cores at higher performance levels which decreases the execution time of the workload and transitions the platform to a low-power system idle state after the completion of the execution of the workload. Since the execution time of the workload is reduced, the platform spends more time in the low-power system idle state and therefore the overall system energy consumption is reduced.
    • 一种用于确定平台或系统的节能工作点的方法和系统。 该平台具有动态管理平台中处理核心和/或平台组件的设置以实现最大系统能量效率的逻辑。 通过使用工作负载和/或平台的特征来确定平台的最佳设置,平台的逻辑有助于平台的性能保证,同时最小化处理器核心和/或平台的能量消耗。 该平台的逻辑确定了以更高的性能水平运行处理核心的机会,这降低了工作负载的执行时间,并且在完成工作负载完成后将平台转换为低功耗系统空闲状态。 由于工作负载的执行时间减少,平台在低功耗系统空闲状态下花费更多时间,因此整体系统能耗降低。
