Shutdown and reset system and method of mainboard software

Abstract

The invention discloses a shutdown and reset system and a shutdown and reset method of mainboard software. The shutdown and reset system comprises a processer, a single EC (electronic computer) chip and a main power supply control chip on a hardware mainboard, wherein the processor is a processer of a hardware mainboard without a south bridge, the processor sends I2C signals, and outputs the I2C signals to an input end of the EC chip; and an output end of the EC chip is connected with an input end of the power supply control chip. The shutdown and reset method of the mainboard software comprises a shutdown method and a reset method. The integral type and desk type computers can be shut down and reset by adopting the independent EC chip so as to realize a domestic loongson CPU (central processing unit) mainboard without the south bridge and a mainboard of a Super IO (input / output) control chip. The shutdown and reset system has low power consumption. The power consumption of the entire mainboard is less than 30watt, and the CPU power consumption on the mainboard is less than 5watt.

Description

technical field [0001] The invention relates to an all-in-one computer and a desktop computer, in particular to a system and method for shutting down and resetting the computer motherboard software of a processor. Background technique [0002] With the development of domestic processor chips and the advent of various computers using processors, their unique motherboard hardware design style has been formed. One of the more special ones is the one based on the Loongson processor without the South Bridge control chip. Hardware motherboard design is mainly used in the design of all-in-one computers. The difference with traditional computers is that there is no south bridge chip and Super IO (super input and output controller). Therefore, compared with the traditional all-in-one computer with south bridge control chip, it cannot complete the communication with the input and output bus interface through the south bridge chip, and complete the operation of switching on and off an...

AI Technical Summary

Problems solved by technology

Therefore, compared with the traditional all-in-one computer with south bridge control chip, it cannot complete the communication with the input and output bus interface through the south bridge chip, and complete the operation of switching on and off and resetting the whole system.

While the computer is in normal working condition, if you want to shut down the computer, you only need to use the hardware switch operation, this hardware method will generate a large surge current, and the frequent switch operation in a short period of time is easy to damage the motherboard. components, shortening the life of the computer
