A signal processing method and electronic device

Abstract

The invention provides a signal processing method and electronic equipment. The method comprises the steps of detecting whether the electronic equipment enters a target state or not, wherein the target state is standby or sleep or power off; when the electronic equipment enters the target state, producing a target control signal; controlling a power supply module to supply power for a voltage regulation module controller through the target control signal so as to realize power-on reset of the voltage regulation module controller, and controlling the power supply module to stop supplying power for the voltage regulation module controller after the power-on reset of the voltage regulation module controller is completed. According to the signal processing method and the electronic equipment provided by the invention, when the electronic equipment enters the target state, the voltage regulation module controller is initialized based on the target control signal, so that when the electronic equipment enters the normal starting state, the voltage regulation module controller can provide the required voltage for a processor, the occurrence of the phenomenon of system halted is avoided, meanwhile, an alternating current power line has no need to be plugged manually, and the user experience is better.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a signal processing method and an electronic device. Background technique [0002] At present, digital power chips are usually used in electronic devices such as PCs or laptops. The digital power chips supply power to the processors of the electronic devices. When the electronic devices are soft-started, there may be a problem that the digital power chip is not initialized and crashes. . [0003] Specifically, because the processor of the electronic device requires the voltage regulation module controller on the digital power chip to provide a voltage of 1.27V, and the maximum output voltage value in the internal register of the voltage regulation module controller is only 1.22V, that is, it cannot process In order to provide the processor with the voltage that meets its requirements, the voltage regulation module controller needs to be initialized, and the voltag...
