Abstract

A processing system includes one or more power supply monitors (PSMs) to measure one or more first voltages corresponding to one or more locations in the processing system. The measurements are performed concurrently with the processing system executing one or more code loops. The processing system also includes calibration logic to modify a second voltage provided to the processing system based on a comparison of a reference voltage and the one or more first voltages. The reference voltage is determined based on previous execution of the one or more code loops by the processing system.
