Power supply control circuit and method for realizing fast start-up of intelligent equipment

Abstract

The invention discloses a power supply control circuit, which includes a power supply module, a DC conversion module, a switch module and an MCU. The input end of the DC conversion module is connected to the power supply module, and the output end is connected to the first storage area of ​​a smart TV to supply power to the first storage area. ; The switch module is used to control the connection state between the output terminal of the DC conversion module and the second storage area of ​​the smart TV, so as to supply power to the second storage area through the DC conversion module; , and output corresponding control signals to the switch module to control the working state of the switch module. The invention also discloses a method for realizing fast startup of the intelligent equipment. When in standby, power is supplied to the first storage area that stores the software code for starting up. When starting up, the first storage area can be directly operated, which realizes the fast booting of smart devices; when in standby, only one storage area is powered, which reduces the power consumption of the first storage area. The operating speed of the memory area reduces the standby power consumption.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to a power supply control circuit and a method for realizing quick start-up of smart devices. Background technique [0002] As the software system of smart devices becomes more complex and the system capacity is larger and larger, it takes longer and longer for smart devices to start up, which takes nearly tens of seconds. Too long waiting time for starting up will seriously affect the user experience. The main steps in the booting process of the smart device are: start the MCU, copy the software code from the flash chip to the DDR memory, and then run the software code in the DDR to initialize each module of the system. In the whole process, copying the software code from the flash chip to the DDR memory and running the software code in the DDR take the longest time. Therefore, if the time of these two processes can be reduced, the boot speed can be improved. At present, the...

Problems solved by technology

At present, the computer will also supply power to DDR when it is in standby, but the computer does not have a standby power consumption requirement when it is in standby, while the standby power consumption requirement of smart devices is very high. Power supply, although it can increase the boot speed, it cannot meet the requirements of standby power consumption
