Abstract

Embodiments of the disclosure provide a performance monitor. The performance monitor may include a memory and at least one processor coupled to the memory. In certain aspects, the at least one processor may be configured to receive a first frequency signal from a frequency source. In certain other aspects, the at least one processor may be configured to receive a second frequency signal from a programmable ring oscillator (PRO). In certain other aspects, the at least one processor may be configured to determine an offset by comparing the first frequency signal to the second frequency signal. In certain other aspects, the at least one processor may be configured to generate a second voltage control signal based at least on the offset. In certain other aspects, the at least one processor may be configured to send the second voltage control signal to a voltage regulator.
