The following is a description of the background of the application and related terms.
The background technology is related:
The current central processing unit generally can reduce the practical upper limit of operating frequency step by step along with the rising of temperature, prevents that the temperature from being too high, but sometimes the user can intuitively perceive phenomenon such as the card that reduces the frequency and bring, in addition, sometimes when needs promote the performance fast, the adjustment of frequency is not fast enough, needs directly promote the frequency lower limit, when promoting the frequency lower limit, sometimes the frequency lower limit that promotes can conflict with the frequency upper limit that the temperature corresponds, leads to appearing the system confusion, very influences user experience.
In order to solve the above problems, embodiments of the present application provide a method for adjusting a frequency of a central processing unit and a related device, which can flexibly adjust an upper frequency limit based on a current application scenario under the condition that the frequency of the central processing unit needs to be adjusted according to temperature, thereby greatly improving user experience.
In the following description of a system architecture of a method for adjusting a frequency of a central processing unit according to an embodiment of the present application with reference to fig. 1, fig. 1 is a system architecture diagram of a method for adjusting a frequency of a central processing unit according to an embodiment of the present application, where the system architecture 100 includes a central processing unit 110, a temperature-frequency control unit 120, and a scene-frequency control unit 130, where the central processing unit 110 has a default upper frequency limit and a default lower frequency limit that are preset, the temperature-frequency control unit 120 may be used to adjust the upper frequency limit and/or the lower frequency limit of the central processing unit 110 according to a current device temperature, and the scene-frequency control unit 130 may be used to temporarily adjust the upper frequency limit and/or the lower frequency limit corresponding to the current device temperature further according to a current application scene.
Through the system architecture, the upper and lower frequency limits can be flexibly adjusted by combining the current application scene on the basis of adjusting the upper and lower frequency limits of the central processing unit according to the temperature, and the user experience is greatly improved.
It will be appreciated that the system architecture described above may be applied to an electronic device, which may be a portable electronic device that also includes other functionality such as personal digital assistant and/or music player functionality, such as a cell phone, tablet computer, wearable electronic device with wireless communication functionality (e.g., a smart watch), etc. Exemplary embodiments of portable electronic devices include, but are not limited to, portable electronic devices that are equipped with IOS systems, android systems, microsoft systems, or other operating systems. The portable electronic device may also be other portable electronic devices such as a Laptop computer (Laptop) or the like. It should also be appreciated that in other embodiments, the electronic device described above may not be a portable electronic device, but rather a desktop computer, server, or the like. And will not be described in detail herein.
The following describes a method for adjusting the frequency of a central processing unit according to an embodiment of the present application with reference to fig. 2, and fig. 2 is a flow chart of a method for adjusting the frequency of a central processing unit according to an embodiment of the present application, which specifically includes the following steps:
In step 201, the default upper frequency limit is adjusted to a first upper frequency limit based on the current device temperature.
The default upper frequency limit is an initial maximum operating frequency of the central processing unit, the first upper frequency limit is used for enabling the operating frequency of the central processing unit to be not higher than the first upper frequency limit, and the first upper frequency limit is lower than the default upper frequency limit.
The first frequency upper limit to be adjusted can be determined according to the mapping relation between the device temperature and the first frequency upper limit, in general, the default frequency upper limit will not change when the device temperature does not reach a certain threshold, for example, when the device temperature is 20 ° -40 °, the device temperature will not affect the central processor, only the default frequency upper limit needs to be maintained, and the device temperature is inversely related to the first frequency upper limit when the device temperature is higher than a certain threshold, for example, the device temperature is 70 °, and at this time, the default frequency upper limit can be reduced to the first frequency upper limit corresponding to 70 ° in order to reduce the temperature. It can be understood that the first upper frequency limit is a frequency point with relatively high energy efficiency ratio at the corresponding equipment temperature, so that the working frequency of the central processor cannot break through the first upper frequency limit, and the influence caused by the equipment temperature can be effectively reduced.
Step 202, if the current application scenario is identified as the first scenario with the user perception degree higher than the preset perception degree threshold, determining a second frequency upper limit meeting the current performance requirement.
The user perception is used for indicating the interaction degree of the user and the device, and the second frequency upper limit is higher than the first frequency upper limit but not higher than the default frequency upper limit, namely the second frequency upper limit is higher than the first frequency upper limit and is smaller than or equal to the default frequency upper limit.
It can be understood that when the user perceptibility is higher than the preset perceptibility threshold value, it is indicated that the user and the device are performing relatively close interaction, the interaction can be directly perceived by the sense organs of the user, at this time, the performance experience of the user is obviously higher, if the first upper frequency limit is maintained, the working frequency of the central processing unit cannot meet the performance requirement, and at this time, the working frequency of the central processing unit cannot meet the performance requirement because of the scene of the close interaction of the user and the device, the phenomenon of blocking, frame dropping and the like which can be obviously perceived by the user is directly reflected, the user experience is very affected, and at this time, a second upper frequency limit meeting the current performance requirement needs to be determined, so as to improve the user experience.
Specifically, the second frequency upper limit can be determined according to the current load type and the current load size, the maximum required calculation force can be determined according to the current load type and the current load size, and the second frequency upper limit corresponding to the maximum required calculation force is determined, and it can be understood that the specific working frequency of the central processing unit is not adjusted at this time, but the boundary of the working frequency is adjusted, so that the method and the device are not required to be very accurate, and only the phenomenon that a user can obviously sense a jam, a frame drop and the like can not occur under the maximum frequency corresponding to the second frequency upper limit is required to be ensured.
And step 203, adjusting the first upper frequency limit to the second upper frequency limit.
The method comprises the steps of determining a current application scene as a first duration of a first scene, and adjusting the first frequency upper limit to the second frequency upper limit in the first duration. It will be appreciated that after the first duration is reached, the second upper frequency limit may be restored to the first upper frequency limit corresponding to the current temperature to prevent the temperature from being too high.
It can be understood that the second frequency upper limit meeting the current performance requirement can be timely opened when the user perception is strong, the problems of blocking and frame dropping are prevented, and the user experience is greatly improved.
The following describes another method for adjusting the frequency of a cpu according to an embodiment of the present application with reference to fig. 3, and fig. 3 is a flowchart of another method for adjusting the frequency of a cpu according to an embodiment of the present application, which specifically includes the following steps:
Step 301, adjusting the default upper frequency limit to a first upper frequency limit according to the current device temperature.
Step 302, determining a user behavior type according to at least one of load data, frequency data and user interaction behavior with the device.
The user behavior type may include a user interface interaction type and a background interaction type, where the user behavior type is the user interface interaction type, it may be understood that the user and the device perform an interaction that the user can obviously perceive, the device needs to present feedback corresponding to the user instruction, and the user behavior type is the background interaction type, where the user and the device perform an interaction that the user cannot obviously perceive, and the device performs corresponding processing in the background.
In a possible embodiment, the user behavior type may be determined to be a user interface interaction type when it is detected that the interaction behavior of the user and the device belongs to a user interface interaction operation, and specifically, the user interface interaction operation may include at least one of a voice interaction operation, a triggering interaction operation, and a space interaction operation, for example, the user clicks, swipes, etc. on a screen of the device, the user performs a voice interaction on the device, and the user uses a space gesture interaction on the device, which is not limited herein. Therefore, the current application scene can be accurately identified as the first scene with stronger user perception degree by detecting the interaction behavior of the user and the equipment. Similarly, if the interaction behavior of the user and the device is detected not to belong to the user interface interaction operation, the user behavior type can be determined to be the background interaction type, such as file decompression, garbage collection, memory cleaning and the like, which is not particularly limited herein.
In a possible embodiment, the user behavior type may be determined to be the user interface interaction type in case it is detected that the load data belongs to the user interface interaction load and/or it is identified that the frequency data corresponds to the first frequency transformation state. Similarly, the user behavior type may be determined to be a background interaction type when the load data is detected to belong to a background load and/or the frequency data is identified to conform to the second frequency change state.
It may be understood that the load data includes a load type of each current load and a load size of each current load, the device may prestore a first load type corresponding to the user interface interaction load and a second load type corresponding to the background load, and may compare and determine whether the first load type and the second load type exist in all current load types, and determine that the main load is determined according to the load size when the first load type and/or the second load type exist in all current load types, and determine that the load data belongs to the user interface interaction load when the main load is the first load type, and determine that the load data belongs to the background interaction load when the main load is the second load type; the frequency data includes frequency variation, it can be understood that, generally, the frequency is adjusted by the frequency modulator (governor), different user behavior types can correspond to different frequency modulation strategies, and the frequency data can be divided into a first frequency modulation strategy corresponding to a user interface interaction type and a second frequency modulation strategy corresponding to a background interaction type, wherein the first frequency modulation strategy can cause the frequency to present a first frequency variation state, and the second frequency modulation strategy can cause the frequency to present a second frequency variation state, so that the frequency modulation strategy corresponding to the frequency variation can be determined, and the current user behavior type can be determined according to the frequency modulation strategy.
Step 303, if the user behavior type is the user interface interaction type, determining that the user perceptibility is higher than a preset perceptibility threshold, and the current application scene is the first scene.
Step 304, if the current application scenario is identified as the first scenario with the user perception degree higher than the preset perception degree threshold, determining a second frequency upper limit meeting the current performance requirement.
Step 305, adjusting the first upper frequency limit to the second upper frequency limit.
Step 306, if the user behavior type is a background interaction type, determining that the user perceptibility is lower than or equal to the preset perceptibility threshold, and the current application scene is a second scene.
Step 307, if the current application scenario is identified as the second scenario with the user perceptibility being lower than or equal to the preset perceptibility threshold, determining a first frequency lower limit meeting the current performance requirement.
The first frequency lower limit is used for enabling the working frequency of the central processing unit to be not lower than the first frequency lower limit, the first frequency lower limit is higher than the default frequency lower limit but not higher than the first frequency upper limit, and it can be understood that in order to improve the efficiency of frequency adjustment, the default frequency lower limit can be directly improved, but sometimes the improved frequency lower limit is higher than the current frequency upper limit, so that the problem of conflict is caused.
It will be appreciated that the minimum required computing force may be determined based on the current load type and current load size, and a first lower frequency limit corresponding to the minimum required computing force may be determined, which may meet the minimum criteria of the current performance requirements.
Step 308, adjusting the default lower frequency limit to the first lower frequency limit.
The current application scene may be determined as a second duration of the second scene, and the default frequency lower limit may be adjusted to be the first frequency lower limit within the second duration. It will be appreciated that after the second duration is reached, the first lower frequency limit may be restored to the default lower frequency limit to prevent excessive temperatures.
And 309, determining a target frequency according to the current performance requirement, and adjusting the central processing unit to the target frequency.
Wherein this step may be performed after step 305 and step 308, the target frequency being within the second upper frequency limit and the first lower frequency limit.
For convenience of understanding, in the following description of the first frequency upper limit, the second frequency upper limit, and the first frequency lower limit in the embodiment of the present application with reference to fig. 4, fig. 4 is a schematic diagram of the first frequency upper limit and the second frequency lower limit of the central processing unit provided in the embodiment of the present application, it can be seen that, when the frequency upper limit needs to be adjusted according to the device temperature, the default frequency upper limit may be adjusted to the first frequency upper limit, and the maximum frequency cannot be higher than the first frequency upper limit, and when the first scene that the current application scene is the first scene that the user perception degree is higher than the preset perception degree threshold is identified, the first frequency upper limit may be adjusted to the second frequency upper limit, and in the first scene, the maximum frequency cannot be higher than the second frequency upper limit, and the second frequency upper limit may be higher than the first frequency upper limit and less than or equal to the default frequency upper limit; under the condition that the current application scene is identified as a second scene with the user perception degree lower than or equal to the preset perception degree threshold, the default frequency lower limit can be adjusted to be a first frequency lower limit according to the current performance requirement, and at the moment, the current lowest frequency cannot be lower than the first frequency lower limit, and the first frequency lower limit is higher than the default frequency lower limit but not higher than the first frequency upper limit.
It can be understood that the second frequency upper limit meeting the current performance requirement can be timely opened when the user perception degree is strong, the problems of blocking and frame dropping are prevented, the default frequency lower limit is timely lifted to the first frequency lower limit when the user perception degree is low, the first frequency lower limit is limited to be incapable of breaking through the first frequency upper limit, and the user experience is greatly promoted.
