By monitoring the frame rate of the application program currently running in the terminal device, the number of cores running on the CPU and/or the operating frequency of the CPU core are dynamically controlled to reduce the Limitations of CPU power consumption and performance optimization.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a control method of a central processing unit disclosed by an embodiment of the present invention. Wherein, the control method of the central processing unit shown in Figure 1 may include the following steps:

101. Monitor the frame rate of the application program currently running in the terminal device;

In the embodiment of the present invention, the terminal device may include a mobile phone, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), and a sales terminal (Point of Sales, POS), etc., the present invention The following examples will not be repeated.

Frame Rate is a metric used to measure the number of frames displayed. The so-called unit of measurement is Frames per Second (FPS) or "Hertz" (Hz). You can modify the source code of the operating system and turn on the frame rate detection switch in the system source code, so as to detect the frame rate of the application program running on the system; or you can also modify the source code of the application program and write the frame rate detection in the application program source code The embodiment of the present invention does not uniquely limit the specific method of detecting the frame rate of the code module and the like.

102. Determine whether the frame rate of the currently running application is less than a first preset threshold;

In the embodiment of the present invention, due to the special physiological structure of human eyes, if the frame rate of the viewed picture is higher than 24, it will be considered coherent, and this phenomenon is called persistence of vision. For games, if the frame rate is less than 30, the game will appear choppy. Therefore, the first preset threshold can be determined based on experience, or determined based on experiments, based on the principle of ensuring the user's smooth use.

103. If it is less than the first preset threshold, increase the number of cores run by the central processing unit and/or the operating frequency of the cores of the central processing unit.

In the embodiment of the present invention, if the frame rate of the application program currently running in the terminal device is less than the first preset threshold, it means that the application program may be stuck when running the application program. Therefore, by increasing the number of cores run by the CPU and and/or the operating frequency of the CPU core to eliminate stuttering.

In the control method of the central processing unit described in FIG. 1, by monitoring the frame rate of the application program currently running in the terminal device; and when the frame rate of the application program currently running in the terminal device is less than the first preset threshold, increase the The number of cores the CPU is running on and/or the operating frequency of the CPU cores. Reduced the limitations of CPU power consumption and performance optimization.

Further, please refer to FIG. 2 . FIG. 2 is a schematic flow chart of another central processing unit control method disclosed in an embodiment of the present invention. Wherein, the control method of the central processing unit shown in Figure 2 may include the following steps:

201. Monitor the frame rate of the application program currently running in the terminal device;

202. Determine whether the frame rate of the above-mentioned currently running application is less than a first preset threshold;

203. If it is less than the first preset threshold, turn on all the cores of the central processing unit; adjust the operating frequency of all the cores of the central processing unit to the highest frequency;

In the embodiment of the present invention, when the frame rate of the application program currently running in the terminal device is lower than the first preset threshold, the CPU in the terminal device is adjusted to output with maximum performance. Wherein, adjusting the CPU in the terminal device to output the maximum performance includes: turning on all cores of the central processing unit; adjusting the working frequency of all the cores of the central processing unit to the highest frequency.

Among them, with the continuous development of electronic technology, the core of the CPU has evolved from single-core to dual-core, quad-core or even eight-core. The more cores can bring faster data processing speed, but generally there will be a certain The performance is idle, so turning on all the cores in the CPU can further increase the data processing speed.

Among them, the CPU frequency is the clock frequency of the CPU. Simply put, it is the abbreviation of the working frequency (the number of synchronous pulses that occur within 1 second) during the CPU operation, and the unit is Hz. It determines the running speed of the computer. With the development of the computer, the main frequency has been developed from the past MHZ to the current GHZ (1GHZ=10^3MHZ=10^6KHZ=10^9HZ). Increase the operating frequency of the CPU and directly set it to the highest designed frequency, which can further increase the data processing speed; of course, you can also choose to adjust it to work at a state that is relatively close to the highest designed frequency.

Furthermore, the highest frequency of the above design can be adjusted through the frequency modulation interface provided by the system of the terminal equipment. For general terminal equipment, the system is equipped with an interface for adjusting the CPU. In the embodiment of the present invention, it can be adjusted in Access this interface to adjust the operating frequency of the CPU during frequency tuning.

204. Determine whether the frame rate of the above-mentioned currently running application is greater than a second preset threshold;

In the embodiment of the present invention, since the increase of CPU energy consumption speed is not directly proportional to the increase of CPU operating frequency, the higher the operating frequency, the higher the energy consumption speed can be said to increase geometrically, so in the actual operation process, The CPU generally maintains a relatively moderate frequency. After the operating frequency is increased, the speed of data processing will not increase significantly, but the losses caused by heat generation and loss will increase significantly. For example, in the process of video playback, generally speaking, 30FPS is acceptable, but increasing the performance to 60FPS can significantly improve the sense of interaction and realism, but generally speaking, it is not easy to notice obvious fluency if it exceeds 75FPS Promoted. If the frame rate exceeds the screen refresh rate, it will only waste graphics processing power, because the monitor cannot update at such a fast rate, so the frame rate exceeding the refresh rate is wasted.

In the embodiment of the present invention, the second preset threshold may be determined according to the refresh rate of the display screen, or determined according to experiments, so as to reduce unnecessary waste of frame rate.

205. If the frame rate of the above-mentioned currently running application program is greater than the second preset threshold, gradually reduce the number of cores run by the CPU and/or the operating frequency of the CPU cores according to preset rules until the currently running application program The frame rate is greater than the first preset threshold but not greater than the second preset threshold;

In the embodiment of the present invention, the preset rule can be set by the user based on experience, or an optimal strategy can be determined based on experiments. When the frame rate of the application program currently running in the terminal device is greater than the second preset threshold, the preset rule A rule is set to gradually reduce the number of cores run by the CPU and/or the operating frequency of the cores of the CPU until the frame rate of the currently running application is greater than the first preset threshold but not greater than the second preset threshold. For example, after reducing the number of cores run by the central processing unit and/or the operating frequency of the cores of the central processing unit according to preset rules, if the frame rate of the application program currently running in the terminal device is still greater than the second preset threshold, continue to follow the preset rule. The rule reduces the number of cores run by the CPU and/or the operating frequency of the cores of the CPU until the frame rate of the currently running application is greater than the first preset threshold but not greater than the second preset threshold.

206. Monitor the temperature of the central processing unit;

In the embodiment of the present invention, after turning on all the cores of the central processing unit; after adjusting the working frequency of all the cores of the central processing unit to the highest frequency, since the heating and loss of the CPU will increase significantly, in order to control the temperature of the CPU, Can monitor CPU temperature in real time.

207. If the temperature of the central processing unit exceeds the preset temperature, reduce the number of cores running on the central processing unit and/or the operating frequency of the cores of the central processing unit.

In the embodiment of the present invention, the preset temperature may be set according to the maximum bearable temperature in the instruction manual of the CPU, or determined according to experiments. When the temperature of the CPU exceeds the preset temperature, the number of cores run by the central processing unit and/or the operating frequency of the cores of the central processing unit are reduced to ensure safe operation of the CPU.
