    • A system and method for prioritization of clock rates in a multi-core processor is provided. Instruction arrival rates are measured during a time interval Ti−1 to Ti by a monitoring module either internal to the processor or operatively interconnected with the processor. Using the measured instruction arrival rates, the monitoring module calculates an optimal instruction arrival rate for each core of the processor. For processors that support continuous frequency changes for cores, each core is then set to an optimal service rate. For processors that only support a discrete set of arrival rates, the optimal rates are mapped to a closest supported rate and the cores are set to the closest supported rate. This procedure is then repeated for each time interval.
    • 提供了一种用于在多核处理器中优先化时钟速率的系统和方法。 指令到达率在时间间隔Ti-1至Ti期间由处理器内部或与处理器可操作地互连的监视模块测量。 使用测量的指令到达率,监视模块为处理器的每个核心计算最佳指令到达速率。 对于支持内核连续频率更改的处理器,每个核心然后设置为最佳服务速率。 对于仅支持离散到达率集合的处理器,最优速率被映射到最接近的支持速率,并且核心被设置为最接近的支持速率。 然后每个时间间隔重复该过程。
