SoC chip, power consumption control method and readable storage medium

Abstract

The invention discloses an SoC chip. The chip comprises a PCU, a DMA controller, a power domain module and a memory, wherein the PCU is used for monitoring a power consumption event and sending initial address information corresponding to the power consumption event to the DMA controller; the DMA controller is used for executing descriptor corresponding operation of the descriptor linked list based on the initial address information; the memory is used for storing the descriptor linked list, the backup state data and the cache data; and the power supply domain module is used for adjusting thepower consumption state under the control of the PCU and / or DMA controller. According to the SoC chip, on the basis of the PCU, the DMA controller and the memory, power consumption control over the granularity of the power domain module can be achieved without extra software intervention, flexible configuration can be achieved, power consumption management requirements of different complex scenescan be met, and the power consumption of the SoC chip can be effectively reduced. The invention also discloses a power consumption control method and a readable storage medium, which have corresponding technical effects.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a SoC chip, a power consumption control method and a readable storage medium. Background technique [0002] With the continuous development and popularization of electronic technology, people's life is closely linked with electronic products. For example, computers, mobile phones, smart watches, wristbands and other IOT (Internet of Things, Internet of Things) electronic products are ubiquitous in daily life. For mobile electronic products such as mobile phones, smart watches, bracelets, etc., they need to be portable and have a long standby time. In this way, low power consumption becomes an important technical index of such mobile electronic products. [0003] Currently, in SoC (System on Chip, System on Chip) chips, there are two schemes for reducing power consumption, one is implemented based on clock gating, and the other is implemented based on power gating....

AI Technical Summary

Problems solved by technology

Although existing solutions to reduce power consumption can reduce power consumption to a certain extent, existing solutions often require software intervention and fixed management methods, which are not suitable for complex application scenarios and cannot effectively reduce SoC chip power consumption
