ABSTRACT:
A system and method is disclosed for providing multi-point calibration of an adaptive voltage scaling (AVS) system. A plurality of Reference Calibration Codes (RCCs) within a multi-point calibration table is provided. Each code is associated with one of the clock frequencies of the adaptive voltage scaling (AVS) system. The present invention provides multi-point calibration by calibrating a Reference Calibration Code (RCC) for each operating point (clock frequency) of the adaptive voltage scaling (AVS) system.
