Description

Method for dynamically modulating frequency of internal memory and electronic equipment

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method for dynamically modulating frequency of an internal memory and an electronic device.

Background

With more and more functions of electronic devices (such as mobile phones and tablet computers), the requirements for data reading and writing of internal memories in the electronic devices are higher and higher, so that the smoothness of operation of the electronic devices in different application scenes is met.

The higher the working frequency of the internal memory is, the faster the data reading and writing speed is, and the smoother the electronic equipment operates. However, the operating frequency of the internal memory is positively correlated with the power consumption of the electronic device. The higher the operating frequency of the internal memory, the greater the power consumption of the electronic device, and the lower the operating frequency of the internal memory, the lower the power consumption of the electronic device. However, when the operating frequency of the internal memory is low, the smoothness of the operation of the electronic device may be affected. Therefore, it is of great practical importance to study the method of adjusting the operating frequency of the internal memory in the electronic device.

the electronic equipment acquires a first load, compares the magnitude relation between the first load and a load threshold, then determines the frequency corresponding to the magnitude relation between the first load and the load threshold as a target frequency from the preset magnitude relation between the load and the load threshold and the frequency, and finally adjusts the working frequency of the internal memory according to the target frequency. Wherein the first load is a command number for accessing the internal memory; the load threshold is determined by the electronic device according to at least two second loads, and the at least two second loads are command numbers which are periodically acquired by the electronic device in a first time period and used for accessing the internal memory.

In the embodiment of the application, the load threshold can be dynamically adjusted based on at least two second loads, so that the electronic equipment can dynamically adjust the working frequency of the internal memory, and the load threshold is determined according to the load condition of the internal memory, so that the working frequency of the internal memory can be adjusted to better meet the performance requirement of the electronic equipment, thereby being beneficial to reducing the power consumption of the electronic equipment while improving the running smoothness of the electronic equipment.

In one possible design, the electronic device determines a first feature value according to at least two second loads, where the first feature value is used to indicate a current operation scene or performance requirement of the electronic device; and determining a threshold corresponding to the first characteristic value in the corresponding relation between the preset characteristic value and the threshold as a load threshold. Through the technical scheme, the implementation mode for determining the load threshold is simplified.

In one possible design, the electronic device determines the first characteristic value as a minimum value, or a maximum value, of the at least two loads; alternatively, the electronic device determines the first characteristic value as an average of at least two loads. Through the technical scheme, the implementation mode for determining the first characteristic value is simplified.

In one possible design, when the electronic device detects that the load threshold does not meet the performance requirement, the load threshold is adjusted according to a preset first policy. The method is beneficial to enabling the load threshold determined by the electronic equipment to meet the performance requirement of the electronic equipment.

In one possible design, the load threshold includes an up-modulation threshold and a down-modulation threshold. Helping to reduce the likelihood of ping-pong effects occurring.

In one possible design, the duration of the period in which the electronic device acquires the second loads is determined by the electronic device from at least two second loads. The method is beneficial to enabling the sampling of the electronic device to meet the performance requirement or the operation scene.

In one possible design, the electronic device periodically obtains the first load. Thereby helping to simplify implementation.

In one possible design, the duration of the period in which the electronic device obtains the first load is the same as the duration of the period in which the electronic device obtains the second load. Which helps to reduce the power consumption of the electronic device.

In some embodiments, the electronic device 100 may reduce the number of times that the modules are used to access the internal memory by presetting a sufficiently large buffer space on the modules that are used to access the internal memory to implement the corresponding functions, such as the processor 110, the camera 153, the audio module 140, etc., so as to help shorten the adjustment interval of the working frequency of the internal memory in the electronic device 100 to be even within 5ms under the condition that the electronic device 100 is operating normally, thereby achieving rapid adjustment of the working frequency of the internal memory and further helping to achieve the purpose of saving power consumption.

It should be noted that, the working frequency of the internal memory in the embodiment of the present application refers to the frequency used when the internal memory is running. It should be understood that in the embodiment of the present application, the internal memory may support at least two frequencies, and the operating frequency of the internal memory is typically one of the frequencies supported by the internal memory. Take the example of LPDDR4X as the internal memory. The highest frequency supported by LPDDR is 2133MHz, the lowest frequency is 415MHz, and the frequency of 830MHz is also supported. Thus, the operating frequency of LPDDR4X may be one of 2133MHz, 415MHz or 830MHz in general.

In some embodiments, the embodiments of the present application may implement fast adjustment of the operating frequency of the internal memory by adding a smart fm module to the electronic device 100. For example, as shown in fig. 4, the smart tuning module 400 includes a statistics module 401, a feature value extraction module 402, and an analysis module 403. In some embodiments smart tuning module 400 may also include a performance detection module 404. In this embodiment of the present application, the smart fm module 400 may be an independent module, or may be integrated on the memory controller 121. The following describes the frequency modulation method according to the embodiment of the present application in detail with reference to the schematic structure of the intelligent frequency modulation module 400 shown in fig. 4.

An exemplary flow chart of a method for dynamically tuning an internal memory according to an embodiment of the present application is shown in fig. 5. Comprising the following steps.

In step 501, the electronic device 100 obtains a first load. Wherein the first load is a command number for accessing the internal memory. In a specific implementation, the memory controller 121 in the electronic device 100 obtains the first load.

It should be noted that the electronic device 100 may periodically acquire the first load. The period of acquiring the first load in the embodiment of the application is a first interval. The first load obtained may be, for example, the total number of commands for accessing the internal memory in the first interval, the number of commands for accessing the internal memory at a time in the first interval, or an average value of commands for accessing the internal memory in the first interval, which is not limited thereto. Taking fig. 6 as an example, the electronic device 100 obtains the first load at time t1, and obtains the first load at time t 2. Wherein the interval between the time t1 and the time t2 is a first interval. Taking time t2 as an example. The number of commands for accessing the internal memory acquired at time t2 may be the number of commands for accessing the internal memory by the electronic device 100 at time t2, or may be the total number of commands for accessing the internal memory by the electronic device 100 in the first interval. Wherein the first interval is from time t1 to time t 2.

In some embodiments, the first interval may be preset in the electronic device 100, for example, 5ms, may be less than 5ms, for example, 3ms, 1ms, and may be greater than 5ms, for example, 10ms.

In other embodiments, the electronic device 100 presets different time intervals, so that the electronic device 100 may choose to select one time interval from the preset different time intervals as the first interval according to different application scenarios or performance requirements. For example, when the remaining power of the electronic device 100 is less than the first threshold, the first interval is determined to be a maximum value of at least one preset time interval. For example, the first threshold may be 20%, 10%, or the like. As another example, the electronic device 100 may determine that the first interval is a minimum value among at least one preset time interval when the remaining power is greater than or equal to the second threshold. For example, the second threshold may be 50% or 80%, or the like, and the second threshold and the first threshold may be the same or different. For example, the preset time intervals are 1ms, 5ms, 10ms, 16ms, and 20ms, and taking the case that the first threshold and the second threshold are 10% each, the electronic device 100 determines that the first time interval is 20ms from 1ms, 5ms, 10ms, 16ms, and 20ms when the remaining power is less than 10%, and the electronic device 100 determines that the first time interval is 1ms from 1ms, 5ms, 10ms, 16ms, and 20ms when the remaining power is greater than or equal to 10%.

In other embodiments, the electronic device 100 may also obtain the first load in response to a triggering event, such as a performance requirement of the electronic device 100 or some particular operating scenario, etc. The embodiment of the application does not limit the acquisition mode of the first load.

At step 502, the electronic device 100 compares the magnitude relation of the first load and the load threshold. In particular implementations, the memory controller 121 in the electronic device 100 compares the magnitude relationship of the first load to the load threshold.

It should be noted that, if the electronic device 100 periodically acquires the first load in step 501, the electronic device 100 may compare the magnitude relationship between the number of commands for accessing the internal memory and the load threshold after each acquisition of the number of commands for accessing the internal memory.

In this embodiment of the present application, the load threshold may be a value, or may be set to a value of the number of commands for accessing the internal memory in a unit duration (for example, 1 s). For example, when the unit time length is ms, the first interval may also be used. By way of example, the load threshold may be 32000/ms. In this case, if the first interval is 1ms, if the number of commands for accessing the internal memory is 30000 in 1ms, the first load is 30000, the magnitude relation between the first load and the load threshold is compared, and if the first interval is 2ms, if the number of commands for accessing the internal memory is 40000 in 2ms, the first load is 20000/ms, the first load (20000/ms) and the load threshold (32000/ms) are compared.

For example, the load threshold may be preset in the electronic device 100. For example, the load threshold may be 32000/s when the first load is the cumulative value of the number of commands for accessing the internal memory in the acquired first interval, and may be a value, for example 30000, when the first load is the number of commands for accessing the internal memory at a certain time in the acquired first interval. As another example, the embodiment of the present application may also set different load thresholds for different operation scenarios or performance requirements of the electronic device 100. For example, for a game scene with high frame rate and high speed variation, the performance requirement is higher, and the preset load threshold is smaller; for application scenes with low frame rate and change requirements, the performance requirement is low, and a high load threshold can be preset. Thus, in some embodiments, the electronic device 100 may determine the current performance requirement and then determine a load threshold corresponding to the current performance requirement. By way of example, the electronic device 100 may determine the current performance requirements from the currently running application, or may determine the current performance requirements based on other means, without limitation.

In some embodiments, the electronic device 100 may also determine the load threshold by periodically retrieving a second load, the second load being the number of commands for accessing the internal memory. The second load may be the total number of commands for accessing the internal memory in the second interval, or the number of commands for accessing the internal memory at a time in the second interval. The relevant description may be referred to as the relevant description of the first load. In particular implementations, in some embodiments, the statistics module 401 of the electronic device 100 periodically obtains the second load.

The period of acquiring the second load is a second interval. The second interval may be different from the first interval or the same. The second interval in the embodiment of the present application may be 1ms, 3ms, 5ms, 10ms, 16ms, 20ms, etc. When the second interval is the same as the first interval, the first load and the second load may be the number of commands for accessing the internal memory in the same interval acquired by the electronic device 100, or the number of commands for accessing the internal memory at the same time in the same interval; or a different number of commands for accessing the internal memory. Thus, the electronic device 100 may determine the load threshold based on the first load (may be the second load) acquired at intervals of the first interval (or the second interval), and may determine the target frequency based on the first load (may be the second load) acquired at intervals of the first interval (or the second interval), thereby helping to reduce the sampling frequency of the electronic device and further helping to reduce the power consumption of the electronic device. By way of example, the second interval is preset in the electronic device 100, for example 1ms, 5ms, 3ms, 10ms, etc. As another example, the electronic device 100 presets different time intervals, so that the electronic device 100 may choose to select one time interval from the preset different time intervals as the second interval according to different application scenarios or performance requirements. For example, for a scene of high frame rate and high speed change (e.g., a scene of a game run by the electronic device 100), the second interval may be set to a smaller duration of 1ms, 2ms, or the like. For a scenario where the read-write requirements of the internal memory are low (e.g. a scenario where the electronic device 100 is running a clock, calendar, phone), the second interval may be set to a longer time interval of 10ms or the like. For example, the electronic device 100 may determine the second interval according to the running application. Thereby helping electronic device 100 save power consumption while meeting performance requirements.

In still other embodiments, the electronic device 100 may also determine the second interval based on the second load. When the electronic device 100 may just start to acquire the second load, because the number of acquired second loads is smaller, the performance requirement of the electronic device 100 cannot be identified, and a default second interval may be adopted. For example, the default second interval may be determined by referring to a description of the preset second interval. After the number of the second loads acquired by the electronic device 100 is sufficiently large, the electronic device 100 may determine the second interval according to the acquired plurality of second loads. In some embodiments, the electronic device 100 determines the load threshold based on a plurality of second loads acquired during the first time period. The first duration may be preset, or may be determined based on a preset policy. For example, the electronic device 100 may determine the second interval at intervals of the first time period according to the plurality of second loads acquired in the first time period. As yet another example, the electronic device 100 may also determine the second interval from a plurality of second loads acquired during the first duration in response to a trigger event (e.g., performance requirement, etc.). For example, the first duration may be 10 minutes, 20 minutes, etc. The first time period may be variable or may be fixed. For example, as shown in fig. 7, the electronic device 100 acquires the second loads at intervals of 1 in the first period of time 1, and if the second intervals determined by the electronic device 100 according to the 5 second loads acquired in the first period of time 1 are 2 intervals, the electronic device 100 acquires the second loads at intervals of 2 intervals from the time t 4. When the electronic apparatus 100 determines the second interval once every first time length, as shown in fig. 7, the electronic apparatus 100 determines the second interval according to the acquired 4 second loads within the first time length 2. If the electronic device 100 determines that the second interval is the second interval 3 according to the 4 second loads acquired in the first time period 2, when the second interval 3 is equal to the second interval 2, the electronic device 100 continues to acquire the second load with the second interval 2 from the time point t8, and when the second interval 3 is not equal to the second interval 2, the electronic device 100 continues to acquire the second load with the second interval 3 from the time point t 8. For another example, when the electronic device 100 determines the second interval according to the plurality of second loads acquired in the first period of time in response to the trigger event, as shown in fig. 7, if the electronic device 100 responds to the trigger event at the time T, the electronic device 100 determines the second interval to be the second interval 2 according to the 4 second loads acquired in the first period of time 2.

For example, the manner in which the electronic device 100 determines the second interval according to the plurality of second loads acquired in the first duration may be as follows:

the electronic device 100 extracts the first characteristic value according to the plurality of second loads acquired in the first duration. And then determining the interval corresponding to the first characteristic value as a second interval from the corresponding relation between the preset characteristic value and the interval. The first characteristic value may be used to indicate a performance requirement or an operational scenario of the electronic device 100. In some embodiments, the electronic device 100 may further determine, according to the extracted first feature value, from a preset correspondence between feature values and thresholds, that a threshold value corresponding to the first feature value is a load threshold. It should be noted that, the electronic device 100 may further determine the load threshold according to the second feature value from the preset correspondence between the feature value and the threshold. The load threshold is a threshold corresponding to the second characteristic value. The second characteristic value may be extracted from at least two third loads. The third load is the number of commands for accessing the internal memory. The third load may be obtained periodically by the electronic device 100, or may be obtained by event triggering of the electronic device 100, which is not limited. When the third load is periodically acquired by the electronic device 100, a period of time of the electronic device 100 for acquiring the third load may be different from the first interval and the second interval, wherein the determining manner of the period of time of the third load may be referred to the determining manner of the second interval. The relevant interpretation of the third load may be referred to as the relevant interpretation of the first load. In the following, the electronic device 100 determines the load threshold according to the extracted first feature value, and the manner in which the electronic device 100 determines the load threshold according to the second feature value may refer to the manner in which the load threshold is determined according to the first feature value.

In some embodiments, after determining the second interval, the electronic device 100 determines whether the determined second interval and/or the load threshold meets the performance requirements of the current operating scenario of the electronic device 100. For example, the performance requirements may be frame rate, latency, etc. If not, the electronic device 100 adjusts the second interval according to the preset first policy and/or adjusts the load threshold according to the second policy. For example, the first strategy may be to shorten the second interval. For example, the electronic device 100 may decrease the second interval by a preset first ratio (e.g., 5%, 10%, or a fixed value), and the second policy may be to decrease the load threshold. For example, the electronic device 100 may decrease the load threshold by a preset second ratio. And then continues to determine whether the reduced second interval and/or load threshold meets the performance requirements of the current operating scenario of the electronic device 100. Until the performance requirements are met. When the second interval and/or the load threshold is adjusted to the limit value and cannot be adjusted continuously, the electronic device 100 may select the second interval and/or the load threshold with optimal performance and power consumption from the adjustment process. Such that the electronic device 100 may update the settings of the second interval based on the newly determined second interval and/or the settings of the load threshold based on the newly determined load threshold.

In particular implementations, in some embodiments, the statistics module 401 of the electronic device 100 sends the obtained second load to the feature extraction module 402. The feature extraction module 402 extracts a first feature value according to the plurality of second loads acquired in the first duration, and sends the first feature value to the analysis module 403. The analysis module 403 determines, according to the first feature value, that the interval corresponding to the first feature value is the second interval from the preset correspondence between the feature value and the interval. In some embodiments, the analysis module 403 may further determine, according to the extracted first feature value, from a preset correspondence between feature values and thresholds, that a threshold value corresponding to the first feature value is a load threshold.

In some embodiments, the analysis module 403 sends the determined second interval to the performance detection module 404. The performance detection module 404 determines whether the second interval and/or the load threshold can meet the current performance requirements of the electronic device 100. For example, taking the performance requirement of a frame rate of 60fps as an example, it is determined whether the second interval and/or the load threshold determined by the analysis module 403 meets the latency requirement at a frame rate of 60fps, and if not, the performance detection module 404 sends an adjustment policy to the analysis module 403. For example, the adjustment policy may include a first adjustment policy that may be to reduce the second interval and/or a second adjustment policy that may be to reduce the load threshold. The ratio of decreasing the second interval and/or the ratio of decreasing the load threshold may be sent by the performance detection module 404 to the analysis module 403, or the analysis module 403 may decrease the second interval according to a preset first ratio and/or send the decreased second interval and/or the decreased load threshold to the performance detection module 404 after decreasing the load threshold according to a preset second ratio. The performance detection module 404 continues to determine whether the reduced second interval and/or the reduced load threshold meet the current performance requirements of the electronic device 100. Until the analysis module 403 receives the notification that the performance detection module 404 has been sent to meet the performance detection, the analysis module 403 sends a second interval and/or a load threshold that meets the performance detection to the storage controller 121. And updating, by the memory controller 121, the settings of the load threshold based on the determined load threshold, and/or the memory controller 121 sends the second interval to the statistics module 401, so that the statistics module 401 updates the settings of the second interval based on the determined second interval. It should be noted that, when the second interval and/or the load threshold cannot be continuously adjusted, the analysis module 403 may select the second interval and/or the load threshold when the performance and the power consumption reach the best in the adjustment process, and send the selected second interval and/or the load threshold to the storage controller 121.

In addition, it should be noted that, when the electronic device 100 uses the load threshold determined based on the obtained at least two second loads, if a frame dropping event occurs during operation of the electronic device 100, and the load threshold determined by the electronic device 100 based on the obtained at least two second loads cannot be continuously adjusted, the load threshold may be directly adjusted to the second load threshold, so that the electronic device 100 may quickly adjust the working frequency of the internal memory to the highest frequency, thereby ensuring the performance of the system. The second-level load threshold may also include an up-threshold and a down-threshold, where when the first load is greater than the up-threshold, the electronic device 100 adjusts the operating frequency of the internal memory to a highest frequency supported by the internal memory, and when the first load is less than the down-threshold, the electronic device 100 adjusts the operating frequency of the internal memory to a first frequency, where the first frequency may be one of the frequencies supported by the internal memory that is less than the highest frequency. In addition, the second-level load threshold may not distinguish between the upper frequency modulation threshold and the lower frequency modulation threshold, and when the electronic device 100 sets the load threshold to the second-level load threshold, the operating frequency of the internal memory may be directly adjusted to the highest frequency supported by the internal memory.

For example, in the corresponding relation between the preset feature value and the interval, when the feature value indicates that the performance requirement of the electronic device changes within the duration of one frame. By way of example, the duration of a frame may be 16.67ms. For example, from a low performance requirement to a high performance requirement, or from a high performance requirement to a low performance requirement, etc., the sampling interval corresponding to the characteristic value is less than the duration of one frame, for example, 1ms, 5ms, etc. For another example, when the feature value indicates that the performance requirement of the electronic device does not substantially change during a duration of one frame, for example, the performance requirement is continuously high, or the performance requirement is continuously medium, or the performance requirement is continuously low, the duration of the sampling interval corresponding to the feature value may be the duration of one frame, or may be greater, for example, 20ms, or the like. Take 5 second loads collected in the first time period 1 as shown in fig. 7 as an example. As can be seen from fig. 7: the electronic device 100 is in a low performance requirement before the time t1 and after the time t3 in the first time length 1, and in a high performance requirement between the time t1 and the time t3, so that the magnitude of the second load is greatly different in the first time length 1, and in this case, the first characteristic value extracted by the electronic device 100 is used to indicate that the performance requirement of the electronic device 100 in the first time length 1 changes. Thus, the second interval corresponding to the first feature value determined by the electronic device 100 is smaller than the first duration 1, e.g. the first duration 1 is a duration of one frame, and the second interval may be, e.g., 1ms, 5ms, etc. Thereby helping to shorten the interval of adjusting the operating frequency of the internal memory.

The first characteristic value may be, for example, a maximum value or a minimum value of two or more command numbers for accessing the internal memory, an average value of two or more command numbers for accessing the internal memory, or the like. In some embodiments, the electronic device 100 may further determine a performance requirement of the electronic device 100 according to a plurality of command numbers for accessing the internal memory in the first period, and then determine a feature value corresponding to the performance requirement of the electronic device 100 according to a correspondence between the performance requirement and the feature value. Wherein the correspondence between the performance requirements and the characteristic values may be preset in the electronic device 100. For example, the electronic device 100 may determine a command number versus time for accessing the internal memory based on the plurality of second loads over the first period of time. The electronic device 100 may determine the performance requirements of the electronic device 100 based on a number of commands to access the internal memory versus time. In addition, it should be noted that, in the embodiment of the present application, the algorithm for extracting the first feature value is not specifically limited.

For example, in the corresponding relation between the preset feature value and the threshold, when the feature value indicates that the performance requirement of the electronic device changes within the duration of one frame, for example, the performance requirement is changed from low performance requirement to high performance requirement, or the performance requirement is changed from high performance requirement to low performance requirement, etc., the threshold corresponding to the feature value is smaller, etc. As another example, the threshold corresponding to the feature value may be a minimum value when the feature value indicates that the performance requirements of the electronic device do not substantially change, e.g., continue to high performance requirements, for a duration of one frame. For another example, the characteristic value indicates that the performance requirement of the electronic device continues to be low for a duration of one frame, then the threshold corresponding to the characteristic value may be a maximum value, or the like.

It should be noted that, in the embodiment of the present application, the load threshold may include an up-frequency modulation threshold and a down-frequency modulation threshold, so as to help reduce the possibility of ping-pong effect.

In step 503, the electronic device 100 determines a target frequency from at least two frequencies supported by the internal memory according to the size relationship. In a specific implementation, the memory controller 121 of the electronic device 100 determines the target frequency from at least two frequencies supported by the internal memory according to the size relationship, for example.

For example, the correspondence between the magnitude relation between the load and the load threshold and the frequency may be preset in the electronic device 100. For example, a correspondence table as shown in table 1.

TABLE 1

In some embodiments, the electronic device 100 may first search a corresponding relationship table corresponding to a load threshold according to the load threshold currently configured by the electronic device 100, and then determine a target frequency from the searched corresponding relationship table, where the target frequency corresponds to a frequency corresponding to a size relationship between the first load and the load threshold.

For example, the internal memory is LPDDR 4X. The highest frequency supported by LPDDR is 2133MHz, the lowest frequency is 415MHz, and the frequency of 830MHz is also supported. Taking an example of an up-frequency modulation threshold and a down-frequency modulation threshold included in the load threshold, if the electronic device 100 is preconfigured with two groups of load thresholds, the load threshold 1 includes 32000 and 29000, and the load threshold 2 includes 20000 and 19000. The table of the correspondence between the magnitude relation of the load and the load threshold 1 and the frequency is shown in table 2, and the table of the correspondence between the magnitude relation of the load and the load threshold 2 and the frequency is shown in table 3.

TABLE 2

Magnitude relation between load and load threshold 1	Frequency of
		Load of more than 32000	830MHz
Load less than 29000	415MHz

TABLE 3 Table 3

Magnitude relation between load and load threshold 2	Frequency of
		The load is more than 20000	2133MHz
Load less than 19000	415MHz

Then in the above scenario, when the first load is 40000 and the load threshold is load threshold 1, the target frequency determined by the electronic device 100 is 830MHz. When the first load is 10000 and the load threshold is 1, the target frequency determined by the electronic device 100 is 415MHz. When the first load is 30000 and the load threshold is load threshold 1, if the working frequency of the internal memory currently set by the electronic device 100 is 830MHz, the determined target frequency is 830MHz. When the first load is 30000 and the load threshold is load threshold 1, if the working frequency of the internal memory currently set by the electronic device 100 is 415MHz, the determined target frequency is 415MHz. However, when the first load is 30000 and the load threshold is 1, if the operating frequency of the internal memory currently set by the electronic device 100 is 2133MHz, the determined target frequency may be any one of 415MHz and 830MHz.

In step 504, the electronic device 100 adjusts the operating frequency of the internal memory according to the target frequency. In a specific implementation, the memory controller 121 in the electronic device 100 adjusts the operating frequency of the internal memory according to the target frequency, for example.

When the working frequency of the internal memory currently set by the electronic device 100 is different from the target frequency, the electronic device 100 adjusts the working frequency of the internal memory to the target frequency; when the operating frequency of the internal memory currently set by the electronic device 100 is the same as the target frequency, the electronic device 100 does not adjust the operating frequency of the internal memory.

For example, if the operating frequency of the internal memory currently set by the electronic device 100 is 415MHz, if the determined target frequency is 415MHz, the operating frequency of the internal memory is kept unchanged in the electronic device 100. As another example, if the operating frequency of the internal memory currently set by the electronic device 100 is 2133MHz, if the determined target frequency is 415MHz, the operating frequency of the internal memory is adjusted to 415MHz by the electronic device 100.

Because the setting modes of the first interval and the second interval in the embodiment of the application can be set based on the performance requirements of the electronic equipment, for example, when the number of the commands for accessing the internal memory is higher, the second interval can be smaller, so that the determined load threshold is more in line with the performance requirements of the running scene of the current electronic equipment, and the electronic equipment can be helped to adjust the working frequency of the internal memory in time. As shown in fig. 8, the load threshold of the electronic device 100 includes an up-tuning threshold 1 and a down-tuning threshold 1, where the up-tuning threshold 1 and the down-tuning threshold 1 are determined based on the second load, and can satisfy the electronic device 100 current performance requirements. Therefore, when the method for adjusting the working frequency of the internal memory is adopted, intra-frame frequency modulation can be realized. As can be seen from a and B in fig. 8: when the electronic device 100 acquires the first load at the first interval, the electronic device 100 can acquire the first load at the time t1 and the time t2, and the frequency up threshold is greater than the frequency up threshold 1 when the first load acquired at the time t1 is acquired, and the electronic device 100 adjusts the operating frequency of the internal memory to be high frequency Fre at the time t1 _high And the electronic device 100 is smaller than the frequency-down threshold when the first load obtained at time t2, the operating frequency of the internal memory is adjusted to be high frequency Fre at time t2 _low . The internal memory of the electronic device 100 thus operates at a high frequency Fre between time t1 and time t2 _high And the internal memory works at a low frequency after the time t2, so that the intra-frame frequency modulation is realized, so that the internal memory works at a high frequency when the number of commands for accessing the internal memory by the electronic equipment 100 is large, and the internal memory works at a low frequency when the number of commands for accessing the internal memory by the electronic equipment 100 is small, thereby being beneficial to ensuring the normal operation of the electronic equipment 100 and reducing the power consumption of the equipment.

Some game application at a frame rate of 60fps runs on a cell phone model number of Mate10 and the internal memory is DDR, with DDR supporting frequencies of 415MHz, 830MHz, 1244MHz and 1866 MHz.

When the DDR operating frequency is adjusted based on the bandwidth size of the memory accessed by the memory controller, wherein the bandwidth size statistics period is 16ms when in up-frequency modulation and 20ms when in down-frequency modulation; the frequency modulation interval is 16ms, when the bandwidth size is greater than 7.3GB/s, the DDR operating frequency is adjusted to 1244MHz, however, for the scene of 60fps frame rate, 7GB/s bandwidth is operated at 830MHz, the game frame rate can drop below 50, and the game experience is seriously affected, so that the mobile phone can ensure the performance by forcedly increasing the DDR operating frequency, and through test, 85% of the DDR operates at 1244MHz and 15% of the DDR operates at 830MHz in the process of running the game with 60fps frame rate. The total power consumption of the cell phone was 500mw, with the cell phone power consumption at 1244MHz for internal DDR being 436mw and at 830MHz for DDR being 64mw.

However, when the frequency modulation method of the embodiment of the present application is adopted, wherein the lower frequency modulation threshold is 32000/s, the upper frequency modulation threshold is 48000/s, the second interval is 1ms, and the first interval is 4ms, when the mobile phone runs a game with a frame rate of 60fps, it is expected that the DDR55% of the time operates at a frequency of 1244MHz, 15% of the time operates at 830MHz, and 30% of the time operates at a frequency of 415MHz under the condition that the frame rate is sufficient. The total power consumption of the electronic device is reduced to 438.4mw, wherein the power consumption is 282mw when the DDR operating frequency is 1244MHz, 64mw when the DDR operating frequency is 830MHz, and 92.4mw when the DDR operating frequency is 415 MHz.

For example, as shown in a of fig. 9, a schematic diagram of the time-dependent change of the operating frequency of the internal memory in the scenario where the electronic device runs a certain game application with a frame rate of 60 fps. As can be seen from the graph shown in fig. 9, the duration of the adjustment interval of the operating frequency of the internal memory is changed, and the change of the operating frequency of the internal memory with time is also changed accordingly. B in fig. 9 is a schematic diagram showing power consumption over time in a scenario in which an electronic device runs a game application with a frame rate of 60 fps. As can be seen from B in fig. 9 and a in fig. 9, the larger the operating frequency of the internal memory, the larger the power consumption of the electronic device, and thus the trend of the power consumption of the electronic device over time is the same as the trend of the operating frequency of the internal memory over time.
