Embodiment Construction

[0014] Such as figure 1 As shown, the Phytium processor communicates with the programmable control chip through two sets of SMBUS, one master and one slave. Since the levels on both sides are inconsistent, a level conversion circuit needs to be added to the bus. The programmable control chip controls the power state through the custom GPIO, and the custom GPIO includes "PM_SLP_S5#", "PM_SLP_S3#", "SYSTEM_RESET#".

[0015] The standby and wake-up operation process is as follows:

[0016] (1), the CPU writes the current information into the memory and writes the status flag to the BIOS;

[0017] (2), CPU writes to the programmable control chip and writes to the standby (S3) state;

[0018] (3) The programmable control chip pulls down the "EC_SLP_S3#" signal to turn off all power supplies except the memory;

[0019] (4) The programmable control chip monitors the wake-up operation, and if the wake-up operation is monitored, perform step 5;

[0020] (5) The programmable contro...

Abstract

The invention provides a method for implementing standby, hibernation and wake-up on a domestic FeiTeng processor, which relates to the field of computer information security. An operating system and a CPU (central processing unit) send standby and hibernation operation commands to a programmable control chip via the SMBUS protocol, and after receiving the commands, the programmable control chip executes the power management of standby and hibernation. The method has the characteristics of simple hardware circuit design and low software code development load, and is a simple and high-efficiency standby and hibernation scheme for FeiTeng portable computers.

Description

[0001] technical field [0002] The invention relates to the field of computer information security, in particular to a method for realizing standby, dormancy and wake-up on a domestic Feiteng processor. Background technique [0003] With the emergence of information security issues, independent and controllable computer systems are increasingly valued by the government and enterprises, and it has become a trend to adopt domestically produced processors, operating systems, and complete systems. Traditional portable notebooks generally adopt the technical architecture of Intel or AMD, and there are a set of mature application solutions for standby, sleep and wake-up functions, that is, communicate with the standard EC (embedded controller) through the LPC bus of the South Bridge, hardware circuits, Both the communication mechanism and the register definition have formed a fixed mechanism. However, domestic Phytium processors need to support sleep, standby and wake-up func...
