Abstract:
1. A computer for realizing household appliance applications with low power consumption, comprising at least a mainboard with a CPU and a computer power supply for supplying power to respective functional devices of said computer, wherein said computer is further provided with a power consumption controller connected to said CPU on the mainboard and said computer power supply, respectively; said CPU on the mainboard receives an external low-power-consumption operation command, detects current application process, when a media application process is detected, it determines a due state of power supply of each of the devices for said media application according to said media application, and based on the determined due state, sends a low-power-consumption control command to said power consumption controller; said power consumption controller receives said low-power-consumption control command, and based on the command, sends a command for reducing the supply voltage or turning off the power supply for each of the devices for said media application to said computer power supply; and said computer power supply reduces the supply voltage or turns off the power supply for each of the devices for said media application according to said command for reducing the supply voltage or turning off the power supply; wherein said power consumption controller is realized with a monolithic microprocessor in a peripheral device of the computer; said computer power supply includes a power supply control module and a power supply module; said power consumption controller is connected via the monolithic microprocessor of the peripheral device to said CPU on the mainboard and the power supply control module of said computer power supply, respectively; the monolithic microprocessor of the peripheral device receives the low-power-consumption control command, and based on the received command, sends to the power supply control module of said computer power supply the command for reducing the supply voltage or turning off the power supply for each of the devices for the media application.
