Abstract
An apparatus includes a processing circuit, a power processing module, and a power management circuit. The power management circuit is configured to estimate, over time, energy consumption of the processing circuit, and to sample the estimated energy consumption using a plurality of different sampling frequencies. Each of the different sampling frequencies is used to generate a respective set of power values. The power management circuit is further configured to track a particular characteristic for each set of power values, and then to provide, for each set of power values, a particular power value that corresponds to the particular characteristic to the power processing module. Based on at least one of the particular power values, the power processing module is configured to adjust an operating parameter of the processing circuit.
