[0002] Currently, most CPU frequency limiting strategies are hardware-based. When electronic devices receive the frequency limiting values ​​from various hardware modules, they typically choose the smallest value as the final maximum CPU frequency. Subsequent adjustments to the CPU frequency by the electronic device cannot exceed this maximum frequency. Therefore, if the determined maximum CPU frequency is too low, it usually leads to noticeable lag in some applications and a poor user experience. Summary of the Invention

[0005] Obtain the perception parameters corresponding to the current task load of the electronic device; wherein, the perception parameters are the parameters corresponding to the modules in the electronic device that are associated with user perception;

[0006] Based on the perception parameters, the task type of the current task load is determined, and the task type includes a perceptible type or an imperceptible type; wherein, the perceptible type indicates that the current task load is related to user perception, and the imperceptible type indicates that the current task load is not related to user perception;

[0007] Based on the frequency limiting policy corresponding to the task type, determine the CPU frequency corresponding to the current task load; wherein, the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the perceptible type is greater than the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the inperceptible type.

[0008] A second aspect of this application provides a CPU frequency adjustment device, comprising:

[0009] A sensing parameter acquisition unit is used to acquire sensing parameters corresponding to the current task load of the electronic device; wherein, the sensing parameters are parameters corresponding to modules in the electronic device that are associated with user perception;

[0010] A task type determination unit is used to determine the task type of the current task load based on the perception parameters. The task type includes a perceptible type or an imperceptible type. The perceptible type indicates that the current task load is related to user perception, and the imperceptible type indicates that the current task load is not related to user perception.

[0011] The frequency determination unit is used to determine the CPU frequency corresponding to the current task load according to the frequency limiting policy corresponding to the task type; wherein, the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the perceptible type is greater than the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the inperceptible type.

[0012] A third aspect of this application provides an electronic device, including:

[0013] Memory containing executable program code;

[0014] and the processor coupled to the memory;

[0015] The processor calls the executable program code stored in the memory, and when the executable program code is executed by the processor, the processor implements the method as described in the first aspect of the embodiments of this application.

[0016] A fourth aspect of this application provides a computer-readable storage medium having executable program code stored thereon, wherein when the executable program code is executed by a processor, it implements the method described in the first aspect of this application.

[0018] The sixth aspect of this application discloses an application publishing platform for publishing computer program products, wherein when the computer program product is run on a computer, the computer executes any of the methods disclosed in the first aspect of this application.

[0019] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0020] In this embodiment, the sensing parameters corresponding to the current task load of the electronic device are obtained; wherein, the sensing parameters are the parameters corresponding to the modules in the electronic device that are associated with user perception; based on the sensing parameters, the task type of the current task load is determined, and the task type includes a perceptible type or an imperceptible type; wherein, a perceptible type indicates that the current task load is related to user perception, and an imperceptible type indicates that the current task load is not related to user perception; based on the frequency limiting policy corresponding to the task type, the CPU frequency corresponding to the current task load is determined; wherein, the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the perceptible type is greater than the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the imperceptible type.

[0021] By implementing this method, electronic devices link CPU frequency limiting to user perception. By analyzing perceived parameters corresponding to the current task load, the task type of the current task load is determined. Then, based on the frequency limiting strategy corresponding to the task type, the CPU frequency corresponding to the current task load is determined, thus achieving differentiated frequency limiting. Furthermore, since the maximum CPU frequency indicated by the frequency limiting strategy for a perceptible task type is greater than the maximum CPU frequency indicated by the frequency limiting strategy for an insensitive task type, the CPU frequency determined by the electronic device for a perceptible task load is generally not too low. This effectively alleviates the application lag problem caused by excessively low CPU frequencies for perceptible task loads. Attached Figure Description

[0028] This application provides a CPU frequency adjustment method, apparatus, electronic device, and storage medium, which can effectively alleviate application lag issues.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. All embodiments based on the present application should fall within the scope of protection of the present application.

[0030] It is understood that the electronic devices involved in the embodiments of this application may include general handheld screen electronic user terminals, such as mobile phones, smartphones, portable terminals, terminals, personal digital assistants (PDAs), portable multimedia players (PMPs), laptops, notebooks, wireless broadband (Wibro) terminals, tablet computers (PCs), smart PCs, point of sale (POS) terminals, and in-vehicle computers, etc.

[0031] Electronic devices can also include wearable devices. Wearable devices are portable electronic devices that can be worn directly on the user's body or integrated into the user's clothing or accessories. Wearable devices are not just hardware devices; they can also achieve powerful intelligent functions through software support, data interaction, and cloud server interaction, such as computing, positioning, and alarm functions. They can also connect to mobile phones and various terminals. Wearable devices can include, but are not limited to, wrist-supported devices (such as watches, wristbands, etc.), foot-supported devices (such as shoes, socks, or other leg-wearing products), head-supported devices (such as glasses, helmets, headbands, etc.), as well as smart clothing, backpacks, canes, accessories, and other non-mainstream product forms.

[0032] To facilitate a clear understanding of the CPU frequency adjustment process by those skilled in the art, an example of an application scenario involved in this application is described below. Please refer to [link / reference]. Figure 1The electronic device 10 first determines the first CPU frequency corresponding to the current task load based on the current task load size. The first CPU frequency refers to the theoretical CPU frequency corresponding to the current task load. Then, the smaller value between the first CPU frequency and the maximum CPU frequency of the electronic device 10 is taken as the CPU frequency corresponding to the current task load, which is the actual CPU frequency of the electronic device 10 when running the current task load. The current task load can represent the number of processes running on the CPU, or the pressure exerted on the CPU by the processes running on the CPU; this embodiment does not limit this. The process corresponding to the current task load can be a process running in the foreground of the electronic device and / or a process running in the background of the electronic device. It should be noted that the larger the current task load, the larger the corresponding first CPU frequency. The first CPU frequency corresponding to the current task load can be obtained by looking up a table, which will be explained in detail below.

[0033] In existing technologies, the maximum CPU frequency of an electronic device 10 is typically determined based on the frequency limiting values ​​corresponding to various frequency limiting modules within the electronic device 10. These frequency limiting modules refer to modules with frequency limiting requirements, and may include temperature control modules, power control modules, etc. Specifically, the electronic device 10 receives frequency limiting requests from various frequency limiting modules, analyzes these requests to obtain the corresponding frequency limiting values, and uses the minimum frequency limiting value among these as the maximum CPU frequency of the electronic device 10. Since the CPU frequency corresponding to the current task load does not exceed the maximum CPU frequency of the electronic device 10, when the initial CPU frequency is significantly higher than the maximum CPU frequency, the CPU frequency corresponding to the current task load becomes the maximum CPU frequency of the electronic device 10. In this case, the application often experiences noticeable lag due to the excessively low CPU frequency corresponding to the current task load, resulting in a poor user experience.

[0034] In this technical solution, the electronic device 10 links CPU frequency limiting with user perception. By analyzing the perceived parameters corresponding to the current task load, it determines the task type of the current task load. Then, based on the frequency limiting strategy corresponding to the task type, it determines the CPU frequency corresponding to the current task load, thereby achieving differentiated frequency limiting. Furthermore, since the maximum value of the CPU frequency indicated by the frequency limiting strategy corresponding to a perceptible type is greater than the maximum value of the CPU frequency indicated by the frequency limiting strategy corresponding to an imperceptible type, when the current task load is a perceptible type, the CPU frequency determined by the electronic device 10 for the current task load will generally not be too low, effectively alleviating the application lag problem caused by the CPU frequency corresponding to a perceptible type of task load being too low.

[0035] Please see Figure 2 , Figure 2 This is a flowchart illustrating a CPU frequency adjustment method disclosed in an embodiment of this application. Figure 2 The CPU frequency adjustment method shown may include the following steps:

[0036] 201. Obtain the perception parameters corresponding to the current task load of the electronic device; wherein, the perception parameters are the parameters corresponding to the modules in the electronic device that are associated with user perception.

[0037] For details regarding the current task load, please refer to the description above; it will not be repeated here.

[0038] In some embodiments, the modules associated with user perception may include any one or a combination of the following: a display module, an audio output module, and a vibration module, etc. The perception parameters corresponding to the current task load may include any one or a combination of the following: screen brightness parameters of the display module, refresh rate of the display module, sound parameters of the audio output module, and vibration parameters of the vibration module, etc. Specifically, the screen brightness parameters indicate whether the display module is on or off, the refresh rate of the display module indicates the output rate of the image on the display module, the sound parameters indicate whether sound is present and / or whether the sound is urgent, and the vibration parameters indicate whether a touch has occurred.

[0039] 202. Based on the perception parameters corresponding to the current task load, determine the task type of the current task load. The task type includes perceptible type or imperceptible type. Among them, perceptible type indicates that the current task load is related to user perception, and imperceptible type indicates that the current task load is not related to user perception.

[0040] In some embodiments, determining the task type of the current task load based on the sensing parameters may include: if the values ​​of each sensing parameter corresponding to the current task load match the values ​​of each sensing parameter corresponding to a perceptible type, then the current task type is a perceptible type; if the values ​​of each sensing parameter corresponding to the current task load match the values ​​of each sensing parameter corresponding to an imperceptible type, then the current task type is an imperceptible type.

[0041] For example, the sensing parameters corresponding to the current task load include the screen-on parameters of the display module, the refresh rate of the display module, the sound parameters of the audio output module, and the vibration parameters of the vibration module. Each parameter has a value of 0 or 1. A screen-on parameter value of 0 indicates that the display module is in a screen-off state, while a value of 1 indicates that the display module is in a screen-on state. A refresh rate value of 0 indicates that the display module does not display an image, while a value of 1 indicates that the display module displays an image. A sound parameter value of 0 indicates that the audio output module does not output sound, while a value of 1 indicates that the audio output module outputs sound. A vibration parameter value of 0 indicates that the vibration module does not vibrate, while a value of 1 indicates that the vibration module vibrates. For perceptible types, the values ​​of each sensing parameter include: at least one sensing parameter is 1; for imperceptible types, the values ​​of each sensing parameter include: all sensing parameters are 0.

[0042] 203. Determine the CPU frequency corresponding to the current task load based on the frequency limiting policy corresponding to the task type; wherein, the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the perceptible type is greater than the maximum value of the CPU frequency indicated by the frequency limiting policy corresponding to the inperceptible type.

[0043] In this embodiment, the task type is an imperceptible type, and the corresponding frequency limiting strategy is that the maximum CPU frequency is determined by the frequency limiting module of the electronic device. The task type is an perceptible type, and the corresponding frequency limiting strategy is that the maximum CPU frequency is determined by the frequency limiting module of the electronic device and overclocking parameters.

[0044] Regarding the method for determining the maximum CPU frequency based on the frequency limiting module of the electronic device, please refer to the description above, which will not be repeated here. Overclocking parameters can indicate the maximum CPU frequency for perceptible types, or the percentage by which it exceeds the maximum CPU frequency for inperceptible types.

[0045] In some embodiments, the overclocking parameters pre-stored by the electronic device can be one or more, and this application embodiment does not limit this. Wherein, if there is one overclocking parameter, it indicates that the overclocking parameters corresponding to each task load of the sensed type are the same; if there are multiple overclocking parameters, it indicates that the overclocking parameters corresponding to each task load of the sensed type are different.

[0046] By implementing the above method, electronic devices link CPU frequency limiting to user perception. By analyzing the perceived parameters corresponding to the current task load, the task type of the current task load is determined. Then, based on the frequency limiting strategy corresponding to the task type, the corresponding CPU frequency is determined, thus achieving differentiated frequency limiting. Furthermore, since the maximum CPU frequency indicated by the frequency limiting strategy for a perceptible task type is greater than the maximum CPU frequency indicated by the frequency limiting strategy for an inperceptible task type, the CPU frequency determined by the electronic device for a perceptible task load is generally not too low. This effectively alleviates the application lag problem caused by excessively low CPU frequencies for perceptible task loads.

[0047] Please see Figure 3 , Figure 3 This is another schematic flowchart of the CPU frequency adjustment method disclosed in the embodiments of this application. Figure 3 The CPU frequency adjustment method shown may include the following steps:

[0048] 301. Obtain the perception parameters corresponding to the current task load of the electronic device; wherein, the perception parameters are the parameters corresponding to the modules in the electronic device that are associated with user perception.

[0049] 302. Based on the perception parameters, determine the task type of the current task load. The task type includes perceptible type or imperceptible type. The perceptible type indicates that the current task load is related to user perception, and the imperceptible type indicates that the current task load is not related to user perception.

[0050] For a description of steps 301-302, please refer to [link / reference needed]. Figure 2 The descriptions of steps 201-202 shown will not be repeated here.

[0051] 303. Determine the first CPU frequency corresponding to the current task load based on the current task load size.

[0052] In some embodiments, the electronic device may have a pre-set load frequency relationship table, which may include multiple CPU frequencies and a load range corresponding to each CPU frequency. The larger the value of the load range, the larger the corresponding CPU frequency.

[0053] Furthermore, determining the first CPU frequency corresponding to the current task load based on the current task load size can include: finding the target load range corresponding to the current task load size from the load frequency relationship table; and using the CPU frequency corresponding to the target load range as the first CPU frequency corresponding to the current task load.

[0054] Given that the current task load represents the pressure exerted on the CPU by the currently running process, for example, if the current task load is 213, the corresponding first CPU frequency obtained from the table is 1478400Hz.

[0055] 304. Determine the maximum CPU frequency corresponding to the current task load based on the frequency limiting policy corresponding to the task type.

[0056] In some embodiments, the task type is an imperceptible type. Determining the maximum CPU frequency corresponding to the current task load based on the frequency limiting policy corresponding to the task type may include: determining a second CPU frequency based on the frequency limiting value corresponding to the frequency limiting module; and using the second CPU frequency as the maximum CPU frequency corresponding to the current task load. The method for determining the second CPU frequency based on the frequency limiting value corresponding to the frequency limiting module can be found in the above description and will not be repeated here.

[0057] In some embodiments, the task type is a perceptible type. Determining the maximum CPU frequency corresponding to the current task load based on the frequency limiting policy corresponding to the task type may include: determining a second CPU frequency based on the frequency limiting value corresponding to the frequency limiting module; determining the target overclocking parameter corresponding to the current task load; and determining the maximum CPU frequency corresponding to the current task load based on the target overclocking parameter and the second CPU frequency.

[0058] In some embodiments, determining the target overclocking parameters corresponding to the current task load may include: obtaining stuttering parameters corresponding to the current task load, wherein the stuttering parameters include the frame rendering duration and / or the execution wait duration of a specified audio thread; determining the target perception level corresponding to the current task load based on the stuttering parameters; and using the overclocking parameters corresponding to the target perception level as the target overclocking parameters corresponding to the current task load.

[0059] In some embodiments, the stuttering parameters include the rendering duration and the execution waiting duration. Determining the target perception level corresponding to the current task load based on the stuttering parameters may include: obtaining a first duration difference between the rendering duration and a rendering duration threshold, determining a first interval in which the first duration difference lies, and obtaining a first stuttering probability corresponding to the first interval; obtaining a second duration difference between the execution waiting duration and an execution waiting duration threshold, determining a second interval in which the second duration difference lies, and obtaining a second stuttering probability corresponding to the second interval; determining a target stuttering probability corresponding to the current task load based on the first stuttering probability and the second stuttering probability; and using the perception level corresponding to the target stuttering probability as the target perception level corresponding to the current task load.

[0060] For example, with a refresh rate of 120Hz, the rendering duration threshold is 8 milliseconds (ms).

[0061] In some embodiments, determining the target lag probability corresponding to the current task load based on the first lag probability and the second lag probability can be achieved in ways including, but not limited to, the following:

[0062] The maximum value between the first lag probability and the second lag probability is determined as the target lag probability corresponding to the current task load;

[0063] or,

[0064] The average of the first and second stutter probabilities is determined as the target stutter probability corresponding to the current task load.

[0065] or,

[0066] The first probability value is obtained by multiplying the first lag probability by the first weighting coefficient, and the second probability value is obtained by multiplying the second lag probability by the second weighting coefficient. Finally, the target lag probability corresponding to the current task load is obtained by adding the first probability value to the second probability value.

[0067] In some embodiments, the electronic device may pre-store a probability level relationship table, which may include multiple perception levels and a probability interval corresponding to each perception level. Further, using the perception level corresponding to the target lag probability as the target perception level corresponding to the current task load may include: searching the probability level relationship table for the target probability interval where the target lag probability lies, and determining the perception level corresponding to the target probability interval as the target perception level corresponding to the current task load.

[0068] By implementing the above method, when the current task load is of a perceptible type, the perceptibility level corresponding to the current task load can be further determined based on the stuttering parameters corresponding to the current task load. Based on the corresponding perceptibility level, the maximum value of the CPU frequency corresponding to the current task load can be determined, allowing for the extent to which the second CPU frequency (the maximum value of the CPU frequency obtained from the frequency limiting module) can be exceeded. For strong perceptibility levels, a large number of exceedances are allowed, while for weak perceptibility levels, a small number of exceedances are allowed. This helps to refine the granularity of CPU frequency adjustment, and the balance between performance and power consumption is more reasonable.

[0069] In some embodiments, the maximum value of the CPU frequency corresponding to the current task load is determined based on the target overclocking parameters and the second CPU frequency, which may include, but is not limited to, the following methods:

[0070] When the target overclocking parameter is the first overclocking parameter: obtain the first computing power value corresponding to the second CPU frequency; determine the second computing power value based on the first computing power value and the first overclocking parameter; and take the frequency corresponding to the second computing power value as the maximum value of the CPU frequency corresponding to the current task load.

[0071] The first overclocking parameter represents the degree to which the first computing power value is exceeded. In some embodiments, determining the second computing power value based on the first computing power value and the first overclocking parameter may include:

[0072] Based on the first computing power value and the first overclocking parameter, the computing power value increment is determined, and the sum of the computing power value increment and the first computing power value is determined as the second computing power value; wherein, the second computing power value = the first computing power value + the first computing power value * the first overclocking parameter;

[0073] or,

[0074] The sum of the first overclocking parameter and 1 is used as the first target coefficient, and the first target coefficient is multiplied by the first computing power value to obtain the second computing power value; where the second computing power value = (1 + first overclocking parameter) * first computing power value.

[0075] It should be noted that the first computing power value corresponding to the second CPU frequency can be obtained by looking up Table 1.

[0076] Frequency (Hz) computing power 307200 45 403200 59 518400 76 614400 90 729600 107 844800 123 960000 140 1075200 157 1171200 171 1267200 185 1363200 188 1478400 216 1574400 230 1689600 247 1785600 261

[0077] Table 1

[0078] For example, if the second CPU frequency is 1171200Hz, the first computing power value is 171, and the first overclocking parameter is 0.1, then the second computing power value = 171 * 1.1 = 188, and the maximum CPU frequency corresponding to the current task load is 1363200Hz.

[0079] When the target overclocking parameter is the second overclocking parameter, the frequency increment is determined based on the second overclocking parameter; based on the second CPU frequency and the frequency increment, the maximum value of the CPU frequency corresponding to the current task load is determined.

[0080] The second overclocking parameter represents the degree to which the second CPU frequency is exceeded. Frequency increment = second CPU frequency * second overclocking parameter; the maximum CPU frequency corresponding to the current task load = second CPU frequency + frequency increment.

[0081] For example, if the second CPU frequency is 1171200Hz and the second overclocking parameter is 0.3, then the maximum CPU frequency corresponding to the current task load is 1171200Hz * 0.3 + 1171200Hz = 1522560Hz.

[0082] By implementing the above method, when the current task load is of a perceptible type, the perceptibility level corresponding to the current task load can be further determined based on the stuttering parameters corresponding to the current task load. Based on the corresponding perceptibility level, the maximum value of the CPU frequency corresponding to the current task load can be determined, allowing for the extent to which the second CPU frequency (the maximum value of the CPU frequency obtained from the frequency limiting module) can be exceeded. For strong perceptibility levels, a large number of exceedances are allowed, while for weak perceptibility levels, a small number of exceedances are allowed. This helps to refine the granularity of CPU frequency adjustment, making the balance between performance and power consumption more reasonable.

[0083] 305. Take the smaller of the first CPU frequency and the maximum value of the CPU frequency as the CPU frequency corresponding to the current task load.

[0084] For example, the first CPU frequency is 1478400Hz, and the second CPU frequency is 1171200Hz. If the current task load is imperceptible, the maximum CPU frequency is 1171200Hz, and the CPU frequency corresponding to the current task load is 1171200Hz. If the current task load is imperceptible, the maximum CPU frequency is allowed to exceed 1171200Hz, specifically 1522560Hz, and the CPU frequency corresponding to the current task load is 1478400Hz.

[0085] By implementing the above method, the electronic device links CPU frequency limiting with user perception. It analyzes the perceived parameters corresponding to the current task load to determine the task type, and then determines the corresponding CPU frequency based on the frequency limiting strategy for that task type, thus achieving differentiated frequency limiting. Furthermore, since the maximum CPU frequency indicated by the frequency limiting strategy for a perceptible task type is greater than that for an inperceptible task type, the CPU frequency determined by the electronic device for a perceptible task load is unlikely to be too low, effectively alleviating application stuttering caused by excessively low CPU frequencies for perceptible task loads. Moreover, the electronic device determines a first CPU frequency corresponding to the current task load based on its magnitude and takes the smaller of this first CPU frequency and the maximum CPU frequency as the CPU frequency for the current task load, which helps improve the rationality of CPU frequency adjustment.

[0086] Please see Figure 4 , Figure 4 This is a structural diagram of a CPU frequency adjustment device disclosed in an embodiment of this application.

The frequency limiting module refers to the module that has frequency limiting requirements.
