A system, method, and medium for adjusting an input clock frequency of a processor in real-time based on one or more hardware metrics. First, the processor is characterized for a plurality of workloads. Next, the frequency sensitivity value of the processor for each of the workloads is calculated. Hardware metrics are also monitored and the values of these metrics are stored for each of the workloads. Then, linear or polynomial regression is performed to match the metrics to the frequency sensitivity of the processor. The linear or polynomial regression will produce a formula and coefficients, and the coefficients are applied to the metrics in real-time to calculate a frequency sensitivity value of an application executing on the processor. Then, the frequency sensitivity value is utilized to determine whether to adjust the input clock frequency of the processor. |
