Technical Field

The embodiment of the application relates to the technical field of chips, in particular to a frequency modulation method and related equipment.

Background

In order to save the production cost of chips, some manufacturers use a common voltage mode when manufacturing two or more frequency-adjustable modules. In the scenario of adopting the shared voltage, if the frequency change of one of the frequency-adjustable modules causes the shared voltage to rise, the shared voltage rises, and the frequency of other frequency-adjustable modules is not adjusted or is not adjusted timely, so that the other frequency-adjustable modules have the condition that the voltage is wasted or the load cannot be met, and the other frequency-adjustable modules have the problems of low energy efficiency, insufficient performance and the like.

For example, in a chip of taiwan concurrent technologies corporation (MediaTek.Inc, MTK), a small core central processing unit (Central Processing Unit, CPU) and a level 3cache (abbreviated as l3 cache) share a voltage; when the workload of the large-core CPU is too high, the frequency of the three-level cache can be increased, and the common voltage can be increased, and the small-core CPU can not be increased in time and continuously works at a low frequency, so that the small-core CPU wastes high voltage or cannot meet the condition of the load, and the problems of low energy efficiency, insufficient performance and the like of the small-core CPU are solved.

Disclosure of Invention

The frequency of the frequency adjustable module of the common voltage can be adjusted in a linkage way, so that high energy efficiency and sufficient performance are ensured.

According to a first aspect, the present application relates to a frequency modulation method applied to an electronic device, the electronic device comprising a first frequency-tunable module and a second frequency-tunable module; the method comprises the following steps: if the frequency of the first frequency adjustable module is increased to cause the voltage shared by the first frequency adjustable module and the second frequency adjustable module to be increased, acquiring a first target frequency of the second frequency adjustable module under a first common voltage, wherein the first common voltage is the voltage shared by the first frequency adjustable module and the second frequency adjustable module after the frequency of the first frequency adjustable module is increased; and determining whether to raise the frequency of the second frequency adjustable module to the first target frequency according to the load of the second frequency adjustable module. The first target frequency may be any frequency of the second frequency adjustable module under the first common voltage, and is preferably the minimum frequency of the second frequency adjustable module under the first common voltage.

In the embodiment of the application, the first frequency adjustable module and the second frequency adjustable module in the electronic equipment share the voltage, when the frequency of the first frequency adjustable module is increased to cause the increase of the shared voltage, the first target frequency of the second frequency adjustable module under the increased shared voltage is obtained, and then whether the frequency of the second frequency adjustable module is increased to the first target frequency is determined according to the load of the second frequency adjustable module. Therefore, the frequencies of the first frequency adjustable module and the second frequency adjustable module of the common voltage can be adjusted in a linkage way, namely, when the frequency of the first frequency adjustable module is increased to cause the increase of the common voltage, the frequency of the second frequency adjustable module can be increased in time, so that the condition that the second frequency adjustable module is wasted in voltage or cannot meet the load is avoided, and therefore high energy efficiency and sufficient performance are ensured. The frequency linkage adjustment of the first frequency adjustable module and the second frequency adjustable module is also adjusted according to the need, namely when the frequency of the first frequency adjustable module is increased, whether the frequency of the second frequency adjustable module is increased is determined according to the load of the second frequency adjustable module; for example, if the second frequency-adjustable module does not need to raise the frequency to meet the load, the frequency of the second frequency-adjustable module is not raised; if the second frequency adjustable module needs to raise the frequency to meet the load, raising the frequency of the second frequency adjustable module; therefore, the frequency of the second frequency adjustable module is not increased unnecessarily, and the additional expense caused by frequent frequency modulation is reduced.

In one possible implementation manner, the determining whether to raise the frequency of the second frequency-tunable module to the first target frequency according to the load of the second frequency-tunable module includes: if the load of the second frequency adjustable module is not greater than a first preset threshold value after the voltage shared by the first frequency adjustable module and the second frequency adjustable module is increased, the frequency of the second frequency adjustable module is not increased to the first target frequency; if the load of the second frequency adjustable module is larger than the first preset threshold value and not larger than the second preset threshold value after the voltage shared by the first frequency adjustable module and the second frequency adjustable module is increased, determining whether to increase the frequency of the second frequency adjustable module to the first target frequency according to the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic equipment; and if the load of the second frequency adjustable module is larger than the second preset threshold value after the voltage shared by the first frequency adjustable module and the second frequency adjustable module is increased, increasing the frequency of the second frequency adjustable module to the first target frequency.

In this implementation manner, after the frequency of the first frequency-adjustable module increases, resulting in an increase in the voltage shared by the first frequency-adjustable module and the second frequency-adjustable module, if the load of the second frequency-adjustable module is not greater than the first preset threshold, which indicates that the load of the second frequency-adjustable module is lower, the load requirement can be met without increasing the frequency of the second frequency-adjustable module, and the frequency of the second frequency-adjustable module is not increased to the first target frequency; therefore, the frequency of the second frequency adjustable module is not required to be increased, and the additional cost caused by frequent frequency modulation is reduced. If the load of the second frequency adjustable module is larger than a second preset threshold value, indicating that the load of the second frequency adjustable module is higher, and increasing the frequency of the second frequency adjustable module is needed to meet the load requirement, increasing the frequency of the second frequency adjustable module to be the first target frequency; therefore, the frequency of the second frequency adjustable module is increased in time, the voltage waste is avoided, and the load cannot be met. If the load of the second frequency adjustable module is larger than the first preset threshold value and not larger than the second preset threshold value, which means that the load of the second frequency adjustable module is not too low or too high, and the frequency of the second frequency adjustable module is in a condition that the frequency can be raised or not, determining whether to raise the frequency of the second frequency adjustable module to the first target frequency according to the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic equipment; thereby avoiding too much reduction of the energy efficiency of the second frequency tunable module or the energy efficiency of the electronic device after the frequency of the second frequency tunable module is increased.

In one possible implementation manner, the determining whether to raise the frequency of the second frequency tunable module to the first target frequency according to the energy efficiency of the second frequency tunable module or the energy efficiency of the electronic device includes: if the frequency of the second frequency adjustable module is increased to the first target frequency, the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic equipment is reduced by a third preset threshold value, and the frequency of the second frequency adjustable module is not increased to the first target frequency; otherwise, the frequency of the second frequency adjustable module is increased to the first target frequency.

In this implementation manner, if the frequency of the second frequency adjustable module is increased to the first target frequency, the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic device is reduced by a third preset threshold, which indicates that the frequency of the second frequency adjustable module is increased, and the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic device is reduced too much, the frequency of the second frequency adjustable module is not increased to the first target frequency, so that the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic device is ensured to be higher, and the performance is also sufficient; otherwise, the frequency of the second frequency adjustable module is raised, and the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic equipment is not reduced too much, so that the frequency of the second frequency adjustable module is raised to the first target frequency, the sufficient performance of the second frequency adjustable module can be ensured, and the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic equipment is also higher.

In one possible implementation, the method further includes: acquiring the frequency of the first frequency adjustable module after the frequency is increased under the condition of monitoring the frequency increase of the first frequency adjustable module; if the frequency of the first frequency adjustable module after the frequency increase is greater than a second target frequency, determining that the frequency increase of the first frequency adjustable module causes the voltage increase shared by the first frequency adjustable module and the second frequency adjustable module, wherein the second target frequency is the maximum frequency of the first frequency adjustable module under a second common voltage, and the second common voltage is the voltage shared by the first frequency adjustable module and the second frequency adjustable module before the frequency increase of the first frequency adjustable module.

In the implementation manner, under the condition that the frequency of the first frequency adjustable module is monitored to be increased, the frequency of the increased first frequency adjustable module is obtained; if the frequency of the first frequency-adjustable module after the rising is greater than the maximum frequency of the first frequency-adjustable module under the common voltage before the rising, the frequency rising of the first frequency-adjustable module is indicated to cause the voltage common to the first frequency-adjustable module and the second frequency-adjustable module to rise. Therefore, the frequency rising of the first frequency adjustable module can be timely monitored, the voltage rising shared by the first frequency adjustable module and the second frequency adjustable module can be timely found, the waste time of the voltage after rising is shortened, and the time for acquiring the first target frequency corresponding to the second frequency adjustable module is reduced.

Detailed Description

First, some technical terms in the embodiments of the present application are described so as to facilitate understanding of the present application by those skilled in the art.

(1) Energy efficiency: refers to the ratio of the energy theoretically available to provide service to the end user to the total energy actually consumed, also known as the energy efficiency ratio.

(2) Energy efficiency ratio curve: the relationship between frequency, voltage and energy efficiency ratio is typically provided by the chip manufacturer or is measured by a laboratory.

(3) Level 3cache (abbreviated as l3 cache): the process of reading data by the central processing unit (Central Processing Unit, CPU) is as follows: searching from the cache file, automatically reading after the cache file is found, and inputting the cache file into a CPU for processing; if the corresponding cache file is not found in the cache, the corresponding cache file is read from the memory and transmitted to the CPU for processing. The third-level cache is a cache designed for reading the missed data after the second-level cache, wherein the first-level cache is built in the CPU and runs at the same speed as the CPU so as to effectively improve the running efficiency of the CPU; the second level cache is a cache designed to coordinate the speed between the first level cache and the memory.

(4) Load: refers to the ratio of the time period of the module run time to the time period.

(5) Power consumption: refers to the amount of energy consumed per unit time.

(6) Frame loss rate: refers to the ratio of the number of lost frames to the theoretical total number of frames over a period of time.

Next, a description will be given of a related art in which two frequency-tunable modules in an electronic device share a voltage scenario, so as to facilitate understanding of the present application by those skilled in the art.

(1) Related art one: some manufacturers set the frequency of one of the frequency-tunable modules to be a fixed value when facing the two frequency-tunable modules to share the voltage scene, and thus the shared voltage is limited and cannot be dynamically adjusted. As shown in fig. 1, the frequency of the second frequency-tunable module is fixed, so that the voltage limit shared by the first frequency-tunable module and the second frequency-tunable module is limited to the highest value.

The related art has the following problems: the overall power consumption of the electronic product provided with the first frequency adjustable module and the second frequency adjustable module is increased, so that the cruising ability is deteriorated, and the user experience is affected.

(2) And related technology II: some manufacturers set the frequency of two frequency-adjustable modules to be adjusted independently when facing the common voltage scene of the two frequency-adjustable modules, but the frequency adjustment of one frequency-adjustable module causes the common voltage to rise, and cannot be linked with the frequency adjustment of the other frequency-adjustable module. As shown in fig. 2, the frequency adjustment of the first frequency-adjustable module causes the common voltage to rise, but does not link the frequency adjustment of the second frequency-adjustable module, so that the second frequency-adjustable module has voltage waste.

The second related art has the following problems: the frequency adjustment that can not link of two frequency adjustable modules, there is the voltage performance can not exert, performance loss's condition for the frequency of two frequency adjustable modules can't reach the combination that energy efficiency is optimal corresponds.

(3) And (3) related technology: some manufacturers do not pay attention to the common voltage when facing the common voltage scene of the two frequency-adjustable modules, but directly do linkage adjustment according to the same proportion of the maximum frequencies of the two frequency-adjustable modules.

The related art three has the following problems: although the frequency changes are kept in the same proportion, the voltage changes corresponding to the frequencies among the frequency-adjustable modules are not in the same proportion, as shown in fig. 3 and 4, wherein the abscissa of fig. 3 and 4 both represent frequency point numbers, indicating what group; the ordinate of FIG. 3 represents frequency (unit: MHz), and the ordinate of FIG. 4 represents voltage (unit: uV); as such, when the frequency is adjusted, there is necessarily a voltage that does not need to be raised to be forced to be raised, resulting in an increase in power consumption. Some frequency-adjustable modules may not need to be increased in frequency to meet performance requirements, but when the frequency-adjustable modules are linked in the same proportion, frequent frequency modulation is necessarily caused for the frequency-adjustable modules, and power consumption is inevitably wasted due to unoccupied frequency increase.

It should be noted that, although the above description only describes the related art in which two frequency-tunable modules share a voltage scenario, the related art is equally applicable to a scenario in which the frequency-tunable modules share more than two voltages.

In view of the drawbacks of the related art, the technical problems to be solved by the present application include: in the scene of shared voltage, how to make full use of power consumption and improve performance.

To the technical problem that this application will solve, this application provides following technical scheme: in a voltage scene shared by a plurality of frequency adjustable modules, when the shared voltage is increased due to the frequency adjustment of one frequency adjustable module, whether the frequencies of other frequency adjustable modules are adjusted in a linkage mode is selected according to the requirement, so that the purposes of fully utilizing power consumption, improving performance and reducing frame loss rate are achieved.

The technical scheme provided by the application is described in detail below in connection with the specific embodiments.

Referring to fig. 5, fig. 5 is a schematic diagram of a scenario in which the first frequency-adjustable module and the second frequency-adjustable module share a voltage, the frequencies of the first frequency-adjustable module and the second frequency-adjustable module can be adjusted independently, and when the frequency adjustment of one frequency-adjustable module causes the increase of the shared voltage, the frequency adjustment of the other frequency-adjustable module can be linked. As shown in fig. 5, when the frequency of the first frequency-tunable module is adjusted (e.g., increased in frequency), resulting in an increase in voltage common to the first frequency-tunable module and the second frequency-tunable module, the frequency of the second frequency-tunable module is increased in linkage. In the process of increasing the frequency of the second frequency adjustable module, the frequency of the second frequency adjustable module is not adjusted in a linkage mode according to the same proportion of the maximum frequency of the two frequency adjustable modules, but the frequency of the second frequency adjustable module is selected to be adjusted in a linkage mode according to actual requirements of the load of the second frequency adjustable module, the energy efficiency of the second frequency adjustable module or the energy efficiency of electronic equipment and the like. The specific process of adjusting the frequency in a linkage manner is shown in fig. 6.

Referring to fig. 6, fig. 6 is a flow chart illustrating a process 600 of a frequency modulation method according to one embodiment of the present application. Process 600 is described as a series of steps or operations, it being understood that process 600 may be performed in various orders and/or concurrently, and is not limited to the order of execution as depicted in fig. 6. Process 600 may be performed by an electronic device comprising a first frequency tunable module and a second frequency tunable module; process 600 includes, but is not limited to, the following steps or operations:

step 601: if the frequency of the first frequency adjustable module is increased to cause the voltage shared by the first frequency adjustable module and the second frequency adjustable module to be increased, a first target frequency of the second frequency adjustable module under a first common voltage is obtained, wherein the first common voltage is the voltage shared by the first frequency adjustable module and the second frequency adjustable module after the frequency of the first frequency adjustable module is increased.

The electronic device can acquire the frequency change condition of any frequency adjustable module of the common voltage in time, and when the frequency of a certain frequency adjustable module is adjusted to cause the increase of the common voltage, the electronic device can acquire the magnitude of the increased common voltage, so that the first target frequency of other frequency adjustable modules of the common voltage under the increased common voltage is further acquired. Alternatively, the first target frequency may be any frequency of the other frequency tunable modules at the raised common voltage, preferably the minimum frequency of the other frequency tunable modules at the raised common voltage.

For example, the first frequency adjustable module and the second frequency adjustable module in the electronic device share the same voltage, the electronic device can timely acquire the frequency change condition of the first frequency adjustable module and the second frequency adjustable module, and if the frequency of the first frequency adjustable module is increased and the voltage shared by the first frequency adjustable module and the second frequency adjustable module is increased, the electronic device can acquire the increased shared voltage, that is, the electronic device can acquire the first public voltage, so as to further acquire the first target frequency of the second frequency adjustable module under the first public voltage. Alternatively, the first target frequency may be any frequency of the second frequency tunable module at the first common voltage, preferably a minimum frequency of the second frequency tunable module at the first common voltage.

Step 602: and determining whether to raise the frequency of the second frequency adjustable module to the first target frequency according to the load of the second frequency adjustable module.

When the frequency of a certain frequency adjustable module is adjusted to cause the common voltage to rise, the common voltage can be timely acquired by the electronic equipment, so that the frequencies of other frequency adjustable modules can be adjusted in a linkage manner; in the process of adjusting the frequencies of the other frequency adjustable modules, whether to adjust the frequencies of the other frequency adjustable modules can be determined according to the loads of the other frequency adjustable modules.

For example, when the frequency of the first frequency adjustable module increases and the voltage shared by the first frequency adjustable module and the second frequency adjustable module increases, the electronic device acquires a first target frequency corresponding to the second frequency adjustable module, so as to determine whether to increase the frequency of the second frequency adjustable module to the first target frequency according to the load of the second frequency adjustable module.

It should be noted that there may be two or more modules sharing the same voltage in the electronic device, and the first frequency-adjustable module and the second frequency-adjustable module may be any two modules sharing the same voltage. It should be understood that when there are only two modules sharing the same voltage, the frequency of one module increases to cause the same voltage to increase, and then the other module is linked to increase the frequency as required, so the first frequency-adjustable module is the module in which the frequency increases to cause the same voltage to increase, and the second frequency-adjustable module is the other module linked to increase the frequency as required; when more than two modules sharing the same voltage are used, the frequency of one module is increased to cause the same voltage to be increased, each module in other modules is linked to increase the frequency according to the requirement, so the first frequency adjustable module is a module in which the frequency is increased to cause the same voltage to be increased, and the second frequency adjustable module is any one of the other modules which are linked to increase the frequency according to the requirement.

After the electronic device obtains the first target frequency of the other frequency adjustable modules of the common voltage under the increased common voltage, the electronic device needs to judge whether the first target frequency can be set or not; the determination condition of whether the first target frequency can be set includes a load determination condition and an energy efficiency determination condition. The following are described respectively:

(1) The load determination conditions are: after the frequency of one frequency adjustable module is increased to cause the increase of the common voltage, if the load of the other frequency adjustable modules is not greater than the first preset threshold value, the load of the other frequency adjustable modules is lower, and the increased frequency has little influence on the performance of the other frequency adjustable modules, so that the frequency of the other frequency adjustable modules does not need to be increased, namely the frequency of the other frequency adjustable modules does not need to be set to be the first target frequency; if the load of the other frequency adjustable modules is larger than the second preset threshold value, the frequency of the other frequency adjustable modules cannot meet the load, so that the frequency of the other frequency adjustable modules needs to be increased, namely the frequency of the other frequency adjustable modules can be set to be the first target frequency; and if the load of the other frequency adjustable modules is larger than the first preset threshold value and not larger than the second preset threshold value, judging through the energy efficiency judging condition.

The first preset threshold value and the second preset threshold value can be selected according to the actual application scene of the frequency adjustable module; as for the second preset threshold, if high performance is required, a low point set by the second preset threshold may be set, and conversely, a high point set by the second preset threshold may be set. For example, the first preset threshold is set to 30% of the full load, when the actual working load of the frequency adjustable module does not exceed 30% of the full load, namely, the frequency of the frequency adjustable module is considered to be low, and the rising frequency has little influence on the performance of the frequency adjustable module; the second preset threshold is set to 60% of full load, and when the actual working load of the frequency adjustable module exceeds 60% of full load, the frequency of the frequency adjustable module is considered to be unable to meet the load.

(2) The energy efficiency judging conditions are as follows: if the frequency of the other frequency adjustable module is set to be the first target frequency, the energy efficiency of the other frequency adjustable module or the energy efficiency of the electronic equipment is reduced by a third preset threshold value, the frequency of the other frequency adjustable module is increased, so that the energy efficiency of the other frequency adjustable module or the energy efficiency of the electronic equipment is reduced too much (or seriously degraded), the reduction degree (or the degradation degree) is not acceptable, and the frequency of the other frequency adjustable module is not set to be the first target frequency; otherwise, it is indicated that raising the frequency of the other frequency-adjustable module does not reduce the energy efficiency of the other frequency-adjustable module or the energy efficiency of the electronic device too much, and the reduction degree is acceptable, so that the frequency of the other frequency-adjustable module can be set to the first target frequency.

The size of the third preset threshold can be selected according to the actual application scene of the frequency adjustable module or the actual application scene of the electronic equipment; if performance is sought, the third preset threshold may be set to a larger value; if a long endurance is pursued, the third preset threshold may be set to a smaller value. For example, when a long endurance is pursued, the third preset threshold is set to 0. In addition, the third preset threshold corresponding to the frequency adjustable module and the third preset threshold corresponding to the electronic device may be the same or different.

The energy efficiency determination may be implemented based on an energy efficiency ratio curve, where the energy efficiency ratio curve may reflect a relationship among frequency, voltage, and energy efficiency, and thus, when an increased common voltage (e.g., a first common voltage) is obtained, and a first target frequency is obtained, after the frequency of another frequency-adjustable module is set to the first target frequency under the increased common voltage (e.g., the first common voltage) and the energy efficiency of the electronic device is determined based on the relationship among the frequency, the voltage, and the energy efficiency in the energy efficiency ratio curve, the energy efficiency of the other frequency-adjustable module or the energy efficiency of the electronic device is determined, thereby determining the degree of decrease in the energy efficiency of the other frequency-adjustable module or the energy efficiency of the electronic device.

Specifically, according to the energy efficiency ratio curve, if the frequency of the second frequency adjustable module is increased to the first target frequency under the first public voltage, the energy efficiency of the second frequency adjustable module or the electronic equipment is determined, so as to determine whether the energy efficiency of the second frequency adjustable module or the energy efficiency of the electronic equipment can reduce a third preset threshold; if the third preset threshold value is lowered, the frequency of the second frequency adjustable module is not raised to the first target frequency; if the third preset threshold is not lowered, the frequency of the second frequency tunable module may be raised to the first target frequency.

The electronic equipment can timely acquire the frequency change condition of any frequency adjustable module of the common voltage, and when the frequency of a certain frequency adjustable module is adjusted, for example, when the frequency of the certain frequency adjustable module is increased, the electronic equipment can also acquire the frequency of the frequency adjustable module after the frequency is increased, and judge whether the frequency after the frequency is increased exceeds the maximum frequency allowed by the frequency adjustable module under the current common voltage; if the maximum frequency allowed by the current public voltage is exceeded, the public voltage is triggered to rise.

For example, when the electronic device monitors that the frequency of the first frequency adjustable module increases, acquiring the frequency of the first frequency adjustable module after the frequency of the first frequency adjustable module increases, and judging whether the frequency of the first frequency adjustable module after the frequency of the first frequency adjustable module increases is larger than the maximum frequency of the first frequency adjustable module under the second common voltage; if it is greater, it is stated that an increase in the frequency of the first frequency-tunable module results in an increase in the voltage common to the first frequency-tunable module and the second frequency-tunable module.

It should be noted that the series of steps or operations described in the process 600 may also correspond to the corresponding description of the embodiment shown in fig. 5.

The process 600 shown in fig. 6 is further described below by way of specific examples shown in fig. 7-11.

Referring to fig. 7, fig. 7 is a schematic diagram of a component architecture of an electronic device according to an embodiment of the present application, where the electronic device may be the electronic device in the embodiment shown in fig. 6, and the electronic device includes an application layer, a kernel layer, and a chip layer.

The application layer is some application programs (APP) that the user can directly perceive.

The kernel layer is located between the application layer and the chip layer, can provide deployment and operation environments for the application layer upwards, and can set chip layer parameters of physical hardware types downwards, and the kernel layer is realized by software. The core layer includes a frequency modulation device including a frequency modulation monitor, a load determination module, an energy efficiency determination module, and a frequency setting module (not shown in fig. 7).

The chip layer includes a module with a common voltage, for example, a first frequency-adjustable module and a second frequency-adjustable module with the common voltage, and the second frequency-adjustable module only symbolically represents one module with the common voltage with the first frequency-adjustable module, so that a plurality of modules with the common voltage with the first frequency-adjustable module may exist in practice.

When the load corresponding to the first frequency adjustable module in the application layer is increased or the first frequency adjustable module is increased due to other reasons, the frequency modulation monitor can timely acquire the frequency to which the first frequency adjustable module is to be increased. In this case, the fm monitor may also timely learn whether the frequency boost of the first frequency-adjustable module results in a voltage boost shared by the first frequency-adjustable module and the second frequency-adjustable module; if the first frequency-adjustable module increases the frequency to cause the common voltage to increase, that is, the common voltage increases to the first common voltage, the fm monitor may timely acquire the first target frequency (e.g., the minimum frequency) of the second frequency-adjustable module under the first common voltage. After the fm monitor obtains the first target frequency, but it is not necessary to set the frequency of the second frequency adjustable module to the first target frequency, the fm device can determine whether to set the frequency of the second frequency adjustable module to the first target frequency as needed. Specifically, the load determination module is required to determine according to the load of the second frequency-adjustable module, and the energy efficiency determination module determines according to the energy efficiency of the second frequency-adjustable module or the energy efficiency of the electronic device, so as to determine whether to set the frequency of the second frequency-adjustable module to the first target frequency.

Wherein, the load judging module judges: whether the frequency of the second frequency tunable module satisfies the load and whether the load of the second frequency tunable module is low enough to raise the frequency has little effect on the performance of the second frequency tunable module. If the load judging module judges that the frequency of the second frequency adjustable module cannot meet the load, the frequency setting module can directly set the frequency of the second frequency adjustable module as the first target frequency; if the load judging module judges that the load of the second frequency adjustable module is lower, the rising frequency has almost no influence on the performance of the second frequency adjustable module, and the frequency setting module does not set the frequency of the second frequency adjustable module as the first target frequency; otherwise, the energy efficiency judgment module is used for further judging.

The energy efficiency judging module judges according to an energy efficiency ratio curve: if the frequency of the second frequency adjustable module is set to the first target frequency, whether the energy efficiency of the second frequency adjustable module is seriously degraded or the energy efficiency ratio of the electronic equipment is seriously degraded is caused. If the energy efficiency judging module judges that the degree of degradation of the energy efficiency degradation of the second frequency adjustable module or the degree of degradation of the energy efficiency degradation of the electronic equipment is acceptable after the frequency of the second frequency adjustable module is set to the first target frequency, the frequency setting module sets the frequency of the second frequency adjustable module to the first target frequency, namely the frequency of the second frequency adjustable module is increased to the first target frequency, and therefore user experience of an application layer is improved; otherwise, the frequency setting module does not set the frequency of the second frequency tunable module to the first target frequency.

In summary, the electronic device shown in fig. 7 is configured to monitor the frequency change condition of each frequency adjustable module by using the fm monitor, so as to timely obtain the change condition of the common voltage, and further calculate the first target frequency of other frequency adjustable modules under the common voltage. Compared with the situation that the frequency of a certain frequency adjustable module of the shared voltage cannot be monitored and the change situation of the shared voltage cannot be judged, the electronic device shown in fig. 7 can discover the change situation of the shared voltage as early as possible, shorten the waste time length after the shared voltage is increased, and reduce the time for acquiring the first target frequency of other frequency adjustable modules.

Further, after the frequency of a certain frequency adjustable module increases to cause the increase of the common voltage, the electronic device shown in fig. 7 may obtain the load condition of other frequency adjustable modules, determine whether the frequencies of the other frequency adjustable modules meet the load, and if not, set the frequencies of the other frequency adjustable modules as the first target frequency; otherwise, judging whether the frequency of other frequency adjustable modules is set as a first target frequency under the increased common voltage according to the energy efficiency ratio curve, wherein the frequency can cause serious energy efficiency degradation; if the energy efficiency degradation degree is acceptable and the load of the other frequency adjustable modules is at a higher position but the frequency of the load meets the load, the frequency of the other frequency adjustable modules can be set as a first target frequency; otherwise, the frequencies of the other frequency tunable modules are not set to the first target frequency. Compared with directly setting the frequencies of other frequency-adjustable modules as the first target frequency after the first target frequency is acquired, the electronic device shown in fig. 7 can effectively adjust the frequencies of other frequency-adjustable modules as required; on one hand, the frequency modulation device is unnecessary to set, and the additional expense caused by frequent frequency modulation is reduced; on the other hand, if the energy efficiency degradation is acceptable, the situation that the energy efficiency degradation is serious and the power consumption is abnormally increased is avoided.

The triggering condition of the frequency increase of the frequency adjustable module includes load increase of the frequency adjustable module, starting performance mode of the frequency adjustable module, setting of other non-shared voltage modules (for example, when the frequency of a CPU is increased and involved IO is more, the system can increase the working frequency of the cache, but the CPU and the cache do not necessarily share voltage), and the like.

Step 802: a voltage rise common to the first frequency tunable module and the second frequency tunable module is monitored.

Referring to fig. 9, fig. 9 is a schematic diagram of a component architecture of another electronic device according to an embodiment of the present disclosure; the electronic device may be the electronic device in the embodiment shown in fig. 6, where the electronic device includes an application layer, a kernel layer, and a chip layer; the application layer and the kernel layer of the electronic device shown in fig. 9 are the same as the application layer and the kernel layer of the electronic device shown in fig. 7, respectively, and the description shown in fig. 7 may be directly referred to, and will not be repeated here.

The chip layer of the electronic device shown in fig. 9 is an MTK breguet 1000 chip, and the electronic device may be a mobile phone using the MTK breguet 1000 chip; in the breguet 1000 chip, the three-level buffer and the small core CPU share a voltage, namely, the three-level buffer corresponds to the first frequency adjustable module and the small core CPU corresponds to the second frequency adjustable module. When the load increases due to more processes started by the application layer, the frequency of the large core CPU in the breguet 1000 chip increases, so that the frequency of the three-level cache is increased along with the increase of the data stream to meet the requirement of high data stream. The increased frequency of the tertiary cache may result in an increased voltage common to the tertiary cache and the coreless CPU. In order to efficiently use the raised common voltage, improve the performance and user experience of the whole machine, the electronic device may perform the following steps or operations:

(1) Setting a frequency modulation monitor.

The main purpose of setting up the frequency modulation monitor is that: monitoring the frequency change condition of the three-level cache, and when the frequency of the three-level cache needs to be increased, acquiring the frequency change condition in time by the frequency modulation monitor; judging whether the voltage shared by the three-level cache and the small core CPU is raised or not according to the frequency to which the three-level cache is to be raised, and if the voltage shared by the three-level cache and the small core CPU is raised, acquiring a first target frequency (such as a minimum frequency) of the small core CPU under the raised shared voltage; otherwise, the frequency modulation monitor continues to monitor the frequency-raising condition of the next three-level buffer.

Referring to fig. 10, fig. 10 is a flowchart of a frequency acquisition method performed by the electronic device shown in fig. 9; the frequency acquisition method includes, but is not limited to, the following steps or operations:

step 1001: setting a frequency modulation monitor.

Step 1002: the system works normally.

Step 1003: it is monitored that the three-level buffer is about to be up-scaled.

The electronic device can monitor that the tertiary buffer is to be up-converted through the frequency modulation monitor.

Step 1004: and judging whether the three-level buffer ascending frequency causes the voltage common to the three-level buffer and the small core CPU to rise or not.

The electronic equipment can judge whether the three-level cache frequency rise causes the voltage rise shared by the three-level cache and the small-core CPU through the frequency modulation monitor; if the voltage shared by the three-level cache and the small core CPU increases due to the frequency rising of the three-level cache, executing step 1005; otherwise, go back to step 1002.

Step 1005: the first target frequency of the small core CPU at the raised common voltage is obtained.

Wherein the electronic device may obtain the first target frequency (e.g., the minimum frequency) through the fm listener.

(2) After the common voltage rises, it is determined whether the frequency of the small core CPU needs to be raised.

After the first target frequency (for example, the minimum frequency) corresponding to the small core CPU is obtained, it is further required to determine whether the first target frequency can be set. The judging conditions are two: one is the load situation of the small core CPU and the other is based on the energy efficiency ratio curve.

Referring to fig. 11, fig. 11 is a flowchart of a frequency modulation method performed by the electronic device shown in fig. 9; the frequency modulation method includes, but is not limited to, the following steps or operations:

step 1101: and judging whether the frequency of the small core CPU meets the load or not.

The electronic equipment can judge whether the frequency of the small core CPU meets the load through the load judging module; if the frequency of the small core CPU cannot meet the load, then step 1104 is performed; otherwise, step 1102 is performed.

Wherein, it can be set that when the load of the small core CPU is more than 60%, the frequency of the small core CPU is considered to be unable to satisfy the load.

Step 1102: and judging whether the load of the small core CPU is lower or not.

The electronic equipment can judge whether the load of the small core CPU is low or not through the load judging module, namely, whether the frequency of the small core CPU is low enough to avoid raising the frequency; if the load of the small core CPU is low, step 1105 is executed; otherwise, step 1103 is performed.

Wherein, it may be set that when the load of the small core CPU is not more than 30%, the load of the small core CPU is considered to be low.

Step 1103: and judging whether the energy efficiency degradation degree is acceptable or not after setting the frequency of the small core CPU as the first target frequency.

The electronic equipment can judge whether the energy efficiency degradation degree is acceptable or not after the frequency of the small core CPU is set to be a first target frequency through the energy efficiency judging module; if the energy efficiency degradation is acceptable, go to step 1104; otherwise, step 1105 is performed.

In this case, the degree of whether the energy efficiency deterioration is acceptable may be set to be conservative, and for example, the energy efficiency deterioration is considered unacceptable as long as it is greater than 0.

Step 1104: the frequency of the small core CPU is set to a first target frequency.

The electronic device may set the frequency of the small core CPU to the first target frequency through the frequency setting module.

Step 1105: the frequency of the small core CPU is not set to the first target frequency.

In summary, in the prior art, the frequencies of the small core CPU and the three-stage cache cannot be adjusted in a linkage manner according to the common voltage rise, so that the frequencies of the small core CPU and the three-stage cache are set independently of each other at most, and therefore waste occurs after the common voltage rise. The method and the device can find out the common voltage rising condition caused by the frequency rising of the three-level cache in time, and then determine whether to raise the small-core CPU frequency according to the requirement, so that the problems of voltage waste and slow frequency rising can be solved, and the effects of fast frequency rising and product overall performance improvement are achieved. When the electronic equipment is a mobile phone, the frame loss rate of the mobile phone can be reduced, the user experience is obviously improved, and the test result shows that: the sliding performance of the mobile phone is reduced from the frame loss rate of 0.0855% to the frame loss rate of 0.0658%, and the performance is improved by more than 20%.
