Abstract

The invention provides a DVS voltage management device, system and method, a storage medium and a computer device. The device comprises a state monitoring unit, a hardware active trigger control unit,a register unit, a software trigger control unit, an arbiter, a state machine and an I2C controller. The state monitoring unit is used for converting a voltage domain state signal into an LPI standard signal; the hardware active trigger control unit is configured to generate a first voltage domain control instruction according to the LPI standard signal; the register unit is used for storing an operation instruction; the software trigger control unit is used for performing the operation instruction and generating a second voltage domain control instruction; the arbiter is used for selecting afirst or second voltage domain control instruction; the state machine is used for controlling the I2C controller; and the I2C controller is used for operating a power management integration circuit under control of the state machine. Therefore, on the basis of combination of the software with the hardware, the chip voltage management is carried out; and the power consumption is low and the compatibility is high.

Description

technical field [0001] The present invention relates to the technical field of voltage management, in particular to a voltage software and hardware adjustment method, specifically a dynamic voltage adjustment (DVS) voltage management device, system and method, storage medium, and computer equipment. Background technique [0002] At present, in order to prolong the battery life and battery life of portable electronic devices (such as mobile phones, MP3 players, notebook computers, etc.), chip developers are racking their brains to develop new power-saving technologies. These power-saving technologies can be roughly divided into two categories, one is dynamic power-saving technology, and the other is static power-saving technology. Static power-saving technologies include different low-power modes, on-demand switching of clocks or power supplies of different components inside the chip, etc. Dynamic power saving technology is to dynamically adjust the operating frequency and v...
