Embodiment

[0034] The computer power management system based on the Loongson processor provided by the present invention includes two parts, the first part is a power management unit, which realizes the power management function of the computer in different operating states through the MCU; the second part is a heat dissipation control system unit, used It is used to solve the heat dissipation problem of the computer in different states.

[0035] Such as figure 1 As shown, the power management unit:

[0036] The localized computer based on the Loongson 3A3000+7A1000 processor implements the power management system function through the MCU controller. The MCU controls the power on and off of each gear through the EN signal. The EN signal is the power enable signal of each gear, which is controlled by the MCU pin. output.

[0037] Power management is centered on Loongson 7A1000 bridge chip and MCU controller. The MCU controller interacts with 7A1000 power management function ACPI to dete...

Abstract

The invention provides a computer power supply management system and method based on a Loongson processor, a medium and equipment. The computer power supply management system comprises: a power supply management unit for performing power supply management on computers in different running states through an MCU controller, and a heat dissipation control unit for carrying out heat dissipation treatment on the computer in different operation states according to the operation power and temperature of the computer. The power management system function is realized through the MCU controller, the problem of power consumption of the computer in different working states is effectively controlled, the problem of high power consumption is solved, and the working time of the computer is prolonged.

Description

technical field [0001] The present invention relates to the technical field of computer power management, in particular to a computer power management system, method, medium and equipment based on a Godson processor. Background technique [0002] Due to the portability of the notebook computer, the battery life of the notebook computer is particularly important, especially when it is powered by a lithium battery in an outdoor environment, the battery life is an important performance index. In the military field, improving the battery life of the notebook computer and prolonging the use time of the notebook computer are especially critical for field military operations. In the context of the localization of electronic information, independent and controllable localized computers have become the first choice for military computers. In view of the particularity of the military reinforced computer case, improving the cooling capacity of the computer is also a very important ind...
