Chip adaptive voltage regulator and method

Abstract

The invention provides a chip adaptive voltage regulator and method. The chip adaptive voltage regulator comprises critical path monitoring modules, an instruction control module and a VRM, wherein the critical path monitoring modules are used for judging whether the current voltage of a chip needs to be boosted or reduced or not, and outputting voltage boosting or reducing instructions when the voltage needs to be boosted or reduced, the instruction control module is connected with the critical path monitoring modules and used for operating the voltage boosting or reducing instructions and outputting a VID value, and the VRM is connected with the instruction control module and used for outputting the corresponding voltage to the chip according to the VID value. According to the voltage regulator, the technical problems that in the prior art, complex large-sample calibration and table lookup need to be carried out when the power supply voltage of a chip is regulated, and the energy-saving effect is reduced due to an insufficient individual difference perception are solved.

Description

technical field [0001] The invention relates to a voltage adjustment technology, in particular to a chip self-adaptive voltage regulator and method for timing critical path monitoring. Background technique [0002] With the continuous improvement of mobile devices and chip integration, device energy consumption and sustainable use time have increasingly become the focus of attention. However, in order to meet various process temperature and frequency conditions, the timing in chip design often has a large voltage margin, while The square of the voltage is proportional to the power consumption, so the voltage adjustment technology is used in the integrated circuit to use different working voltages under different load conditions of the integrated circuit, so as to achieve the purpose of reducing the power consumption of the chip. [0003] In the prior art, such as figure 1 As shown, the working voltage of the chip is adjusted through Adaptive Voltage Scaling (AVS) technology...
