Abstract:
Embodiments of the present invention provide an adaptive voltage scaling method, chip, and device. An aging effect-related state parameter in a chip is obtained at a first voltage adjustment time point. The first voltage adjustment time point is one of multiple voltage adjustment time points set for the chip. An aging compensation voltage corresponding to the first voltage adjustment time point is determined according to the state parameter. A minimum operating voltage of the chip is compensated for according to the aging compensation voltage, so as to adjust an operating voltage of the chip.
