Embodiment approach

[0017] Please continue to refer figure 2 A preferred embodiment of the load detection method of the present invention includes the following steps:

[0018] Step S1: The central processing unit 10 works under the rated maximum voltage.

[0019] Step S2: Record the input voltage signal received by the super input and output device 30 at this time, and at this time, the input voltage signal is the full-load voltage value Vfull of the central processing unit 10 .

[0020] Step S3: multiply the full-load voltage value Vfull by a first coefficient to obtain the heavy-load voltage value, which is the upper limit voltage value Vhigh, and a second coefficient to obtain the light-load voltage value, which is the lower limit voltage value Vlow, where The first and second coefficients can be obtained through experience or experimental data. Generally, the upper limit voltage Vhigh is 95%-100% of the full-load voltage value Vfull, and the lower limit voltage Vlow is 90%-95% of the full-...

Abstract

The invention provides a load detection system, which is used for detecting the load of a hardware function module with voltage variation. The load detection system comprises a functional chip which is connected with the hardware function module and an interrupt controller which is connected with the functional chip, wherein the functional chip is internally stored with a voltage upper limit valueand a voltage lower limit value; the functional chip is used for sensing the voltage signals of the hardware function module, comparing the voltage signals with the voltage upper limit value and thevoltage lower limit value to maintain the original working condition of the hardware function module or output an interrupt signal to the interrupt controller according to the comparing results; and the interrupt controller is used for changing the working condition of the hardware function module correspondingly according to the interrupt signals. The load detection system does not generate additional system resource consumption brought about by software polling. The invention also provides a load detection method.

Description

technical field [0001] The invention relates to a load detection system and method. Background technique [0002] In today's computer systems, power saving has always been an important issue. The central processing unit (CPU) with intelligent frequency reduction function can automatically adjust its own voltage and frequency according to the load of the processor, so as to reduce power consumption and heat generation. [0003] At present, the load of the processor is generally detected by software, that is, the load of the processor is inquired by the software loop to perform related processing according to the load of the processor, but the loop query by the software will occupy additional system resources. . Contents of the invention [0004] In view of the above, it is necessary to provide a load detection system and method that does not occupy additional system resources. [0005] A load detection system for detecting the load of a hardware function module with volt...
