Abstract

The invention discloses a voltage adaptive adjustment circuit and a chip. The voltage self-adaptive adjustment circuit includes a performance classification monitor and an adaptive controller. The performance classification monitor is set inside the chip to detect the working performance of the chip under the current working voltage and output the detection to the adaptive controller. Result signal; the adaptive controller is connected with the performance classification monitor, and is used to output a control signal to the power management module of the chip according to the detection result signal output by the performance classification monitor, and the control signal is used to control the power management module to adjust the work of the chip Voltage. The embodiments of the present invention can reduce the testing workload.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and more specifically, relate to a voltage self-adaptive adjustment circuit and chip. Background technique [0002] With the development of chip manufacturing technology and the improvement of design integration, the problem of chip power consumption has become an urgent problem to be solved. Technologies to reduce chip power consumption In addition to traditional clock gating and other technologies, Adaptive Voltage Scaling (AVS, AdaptiveVoltage Scaling) technology has attracted much attention as a new effective and important low power consumption technology. Among them, determining the minimum operating voltage of the chip is the core step of implementing the AVS technology, and the minimum operating voltage must meet the safety requirements of the system under the worst operating conditions. Adding an appropriate voltage margin on the basis of the minimum operating v...
