Embodiment 1

[0041] Such as Figure 1 to Figure 2 As shown, a portable terminal power management method based on the Loongson processor includes a main processor, a Loongson 1B processor and a battery connected in sequence, and performs the following steps:

[0042] A. Reset the chip of the Loongson 1B processor, generate a pulse on the RST pin of the Loongson 1B processor, the Loongson 1B processor enters the startup state, and each functional module works according to the power-on sequence. After initializing the basic memory and other controllers, Boot into the RT-Thread operating system, complete the basic system parameter initialization and I2C controller parameter configuration required for communication, and wait for the main processor to send instructions and data;

[0043]B. Establish a connection between the main processor and the Loongson 1B processor through the communication interface. After reset, the RT-Thread system of the Loongson 1B processor has been started, and the pow...

Embodiment 2

[0050] Based on Embodiment 1, in this embodiment, the domestic Loongson 3A processor is used as the main processor, and 2GB DDR3 SDRAM is plugged in. The system has two 8GB mSATA hard disks, one for general data storage and the other for special data storage. The hard disk has the function of intelligent data destruction. The display adopts a capacitive touch-type 7-inch 1280×800 resolution high-definition IPS display. The main system runs the winning Kirin Linux operating system. The entire system has low power consumption and a wide operating temperature range without special heat dissipation management. When the current system needs power management, if the previous power management solution of non-domestic chips is used, there will be great challenges in the transformation of the system's Chinese-made circuits, and the workload will be huge.

[0051] The chip used for power management in this embodiment adopts the domestic processor Loongson 1B processor of Zhongke Loongso...

Abstract

The invention discloses a portable terminal power supply management method based on a Loongson processor. The method comprises the following steps: resetting a chip; the communication interface establishing connection; reading the ACPI information; the Loongson 1B processor communicates with the information of the battery and controls the battery to be charged; according to the current state change event or the information of the battery, the Loongson 1B processor performs power supply control on the main processor system; according to the temperature condition of the current circuit, the Loongson 1B processor controls the fan; the health state of the main processor system is managed through the Loongson 1B processor; the invention provides a portable terminal power supply management method based on a Loongson processor. During application, the Loongson processor chip has the I2C and serial port communication functions and is matched with a domestic system to build a power management communication framework and a management system, the autonomous controllability problem of the power management system is solved, meanwhile, the power management system can be expanded to application occasions of other multi-framework processor systems, and high practicability and popularization performance are achieved.

Description

technical field [0001] The invention relates to a portable power supply, in particular to a method for managing the power supply of a portable terminal based on a Godson processor. Background technique [0002] The hardware design of the portable terminal power management solution in the current market mainly adopts the power management special solutions of two foreign processor chip manufacturers, and the power management software system is based on the dedicated supporting software development kit (SDK) provided by the corresponding chip manufacturers. developed for the second time. [0003] The main methods involved in its power management system are as follows: [0004] Using the I2C, serial port and other interfaces that come with the processor, the power control logic is established through the SDK interface to respond to the power processing requirements from the system respectively. At the same time, the system is responsible for communicating with the battery to ob...
