Method for measuring integrated circuit processor power demand and associated system |
摘要 |
A system and method for measuring integrated circuit processor power demand comprises calibrating one or more voltage controlled oscillators for use as ammeters, calibrating a calibration current source, wherein the calibration current source draws current through a inherent resistance, calibrating the inherent resistance, and interleaving said calibrations in time with calculating the processor power demand using a voltage that is measured across the inherent resistance.
