Abstract

The present invention discloses an adaptive voltage scaling circuit and a chip. The adaptive voltage scaling circuit includes a performance classification monitor and an adaptive controller, where the performance classification monitor is disposed inside the chip, and is configured to detect working performance of the chip at a current working voltage, and output a detection result signal to the adaptive controller; and the adaptive controller is connected to the performance classification monitor, and is configured to output a control signal to a power management module of the chip according to the detection result signal output by the performance classification monitor, where the control signal is used to control the power management module to adjust a working voltage of the chip. In embodiments of the present invention, test workload can be reduced.
