Problems solved by technology

[0006] 1. Since the manufacturer's feedback speed is not too fast, time-consuming is inevitable
Therefore, the development time of the test program will be increased
[0007] 2. The models of calculators are constantly being introduced, and the models produced in the past will not be discarded immediately. Therefore, the test program must take into account the models of the past and apply to the models that have just been produced. Causes the length of the program code, which is not conducive to the maintenance of the program
[0008] 3. The temperature extraction method is not universal, the program is always being updated, and the input of manpower and material resources will continue to increase the cost, resulting in a waste of capital

Embodiment Construction

[0054] Relevant detailed content and technology of the present invention, cooperate accompanying drawing to illustrate as follows:

[0055]At present, most computers support the Advanced Configuration and Power Management Interface (ACPI). The so-called Advanced Power Management Protocol is some table structures and some binary numbers. These table structures and binary numbers have been solidified into the BIOS of the calculator. In, and before the operating system is activated, it has been transferred into the memory, part of which cannot be changed by the operating system. In this part of the fixed content, it contains hardware information, including hardware port address, operation offset and hardware operand. Among these hardware information, there is related content of CPU temperature. These contents are recorded in the form of binary code, which can be translated into a statement according to the specification of the Advanced Power Management Protocol, but this stateme...

Abstract

The invention relates to a general method for reading the temperature of CPU, which first reads AML code form BIOS according to advanced power managing agreement; and then it ascertains the hardware path for reading CPU temperature in the AML code; then ascertains the hardware port and operating code of executing temperature according to the hardware path, then analyzes the AML code to ascertain hardware port operating order, at last reads CPU temperature by the operating order and operating hardware port.

Description

technical field [0001] The invention relates to a method for reading the temperature of a central processing unit, in particular to a general method for reading the temperature of the central processing unit. Background technique [0002] With the development of the computer industry, the update speed of calculators is getting faster and faster. Therefore, the output of current computers is also gradually increasing. Before every new computer leaves the factory, it must be fully tested to verify that its performance is up to standard. Among them, the central processing unit (CPU) is the main detection item. The current CPU speed is relatively satisfactory, but the heat generation of the CPU has become a problem that users generally pay attention to. CPU temperature is very important for calculators, overheating will cause damage to components, so when testing the performance of calculators, CPU temperature is an important parameter index. [0003] The test of CPU temperat...
