Chip frequency regulation method

Abstract

The invention provides a method for chip frequency adjustment, regularly measures the chip temperature, can modify the chip BIOS information that has been transferred into the memory part according to the amount of tasks to be processed, dynamically adjust the chip operating frequency, and adjust the chip operating frequency to be suitable for actual work. Frequency, to achieve the purpose of giving full play to the processing capability of the chip and effectively improving the service life of the chip. In addition, the upper limit protection of the chip temperature is adopted in the control of improving the processing capability, and the chip frequency cannot be increased without limit. How many tasks can be done and how much processing power can be provided, so that when the amount of tasks to be processed is small, the chip itself works at a lower frequency, which saves energy on the one hand and prolongs the life of the chip on the other hand; When the workload is large, the chip works at a higher frequency.

Description

technical field [0001] The invention relates to a frequency adjustment method, in particular to a chip frequency adjustment method. Background technique [0002] At present, in the field of electronics, the application of large-scale integrated circuits and ultra-large-scale integrated circuits is becoming more and more common. One of the important performance parameters of various integrated circuits is the operating frequency. The operating frequency defines the computing speed of the chip. Under the condition of the same chip function, the higher the chip frequency, the stronger the computing power. Taking the CPU in the computer field as an example, it is also a Pentium 4 series CPU with a 1.8GHz , there are 2.0GHz, their internal functional structure and production process are completely the same, they are cut from the same wafer, the only difference is the frequency at which they can work stably. Due to the small differences inside the crystal during the wafer manufac...

Problems solved by technology

[0004] While the operating frequency of the chip determines the computing speed of the chip, it also has a great impact on the service life of the chip, because under the same operating voltage, different loads of tasks require different operating currents, and the generated heat is also different. If the chip is always working at full load, a higher input current will be required, and the overall heat generation will increase, greatly shortening the service life of the chip

[0005] In actual use, only a small number of applications require the chip to work at 100% processing power. Taking the CPU as an example, various applications only use 50%-70% of the processing power of the CPU most of the time, and only a few The application requires the CPU to work at full load for a long time

This has caused the following disadvantages: on the one hand, the CPU still works at a higher frequency when it does not need to provide high processing power, which wastes resources and shortens the service life of the chip; Sometimes, because the protection settings reserved in the factory settings limit the chip's maximum processing capacity, it also causes waste

[0006] Taking the display card as an example, in actual applications, as ordinary commercial users and home users, more than 70% of the graphics processing capabilities required by the applications are only simple 2D operations and a small part of 3D operations. In terms of the processing power of the company's geforce2 series MX400, only less than 40% is used

However, for a small number of professional graphics users or 3D game users, the display cards configured in the system have not been able to make the best use of everything.

[0007] This is like a light bulb with a maximum power of 150W. The manufacturer has set it to 100W for the sake of safety. Only 50W is enough for daily use at home. Because it cannot be adjusted, it can only waste a lot of power; and sometimes it needs 130W. Although The bulb itself can work according to 130W, but because of the limitation of the factory settings, it cannot play its maximum role
