Method and device for dynamic adjustment of network operating voltage

Abstract

The present invention is to provide a method and device of dynamically adjusting the operating voltage of a network integrated circuit including the steps of detecting and ranking the signal-to-noise ratio of N ports to single out a port for arbitration, dynamically controlling the operating voltage according to the signal-to-noise ratio of the port for arbitration, decreasing the operating voltage by a voltage unit when the signal-to-noise ratio of the port for arbitration is greater than a first threshold, increasing the operating voltage to a default operating voltage when the signal-to-noise ratio of the port for arbitration is smaller than the first threshold, decreasing the operating voltage by a voltage unit when the signal-to-noise ratio of the port for arbitration is greater than a second threshold, and increasing the operating voltage by a voltage unit when the signal-to-noise ratio of the port for arbitration is smaller than the second threshold.
