Method for dynamically modulating frequency of internal memory and electronic equipment

Technical Field

The present disclosure 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 the increasing functions of electronic devices (such as mobile phones and tablet computers), the requirements for reading and writing data of internal memories in the electronic devices are also higher and higher, so as to meet the smoothness of the operation of the electronic devices in different application scenes.

The higher the working frequency of the internal memory is, the higher the data reading and writing speed is, and the smoother the electronic equipment runs. 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 is, the higher the power consumption of the electronic device is, and the lower the operating frequency of the internal memory is, the lower the power consumption of the electronic device is. However, when the operating frequency of the internal memory is low, the smoothness of the operation of the electronic device may be affected. Therefore, the research on the method for adjusting the operating frequency of the internal memory in the electronic device has important practical significance.

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

Through the technical scheme, the implementation mode of determining the first characteristic value is facilitated to be 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.

Take the example where the internal memory is LPDDR 4X. The highest frequency supported by LPDDR is 2133MHz, the lowest frequency is 415MHz, and in addition, a frequency of 830MHz is supported. Thus, the operating frequency of LPDDR4X may typically be one of 2133MHz, 415MHz, or 830 MHz.

In some embodiments, 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 fm module 400 includes a statistics module 401, a feature value extraction module 402, and an analysis module 403. Smart fm module 400 may also include performance detection module 404 in some embodiments. In the 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 method for tuning frequency according to the embodiment of the present application is described in detail below with reference to the schematic structural diagram of the smart frequency tuning module 400 shown in fig. 4.

For example, as shown in fig. 5, a flowchart of a method for dynamically tuning an internal memory according to an embodiment of the present application is shown. Comprises the following steps.

In step 501, the electronic device 100 obtains a first load. Wherein the first payload is a number of commands for accessing the internal memory. In particular implementations, 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. In this embodiment of the present application, a duration of a cycle of acquiring a first load is a first interval. For example, the obtained first load may be a total number of commands for accessing the internal memory in the first interval, may also be a number of commands for accessing the internal memory at a certain time in the first interval, may also be an average value of the commands for accessing the internal memory in the first interval, and the like, which is not limited herein. Taking fig. 6 as an example, the electronic device 100 acquires the first load at time t1, and acquires the first load at time t 2. Wherein the interval between time t1 and time t2 is the first interval. Take 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 electronic device 100 at time t2, or the total number of commands for accessing the internal memory by electronic device 100 in the first interval. Wherein the first interval refers to starting from time t1 and ending at time t 2.

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

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

In other embodiments, the electronic device 100 may further obtain the first load in response to a triggering event, such as a performance requirement or some specific operation scenario of the electronic device 100. The embodiment of the present application does not limit the manner of acquiring the first load.

In step 502, the electronic device 100 compares the magnitude relationship between the first load and the load threshold. In a specific implementation, the memory controller 121 in the electronic device 100 compares the magnitude relationship between the first load and 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 size relationship between the number of commands for accessing the internal memory and the load threshold after acquiring the number of commands for accessing the internal memory each time.

In the embodiment of the present application, the load threshold may be a value, or may be set as a value of the number of commands for accessing the internal memory in a unit time length (for example, 1 s). Illustratively, when the unit duration is ms, the first interval may be also used. For example, the loading threshold may be 32000/ms. In this case, if the first interval is 1ms, if the number of commands for accessing the internal memory within 1ms acquired is 30000, the first load is 30000, the magnitude relationship 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 within 2ms acquired is 40000, 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 loading threshold may be 32000/s when the first loading is an accumulated 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 loading is the number of commands for accessing the internal memory at a certain time in the acquired first interval. As another example, in the embodiment of the present application, different load thresholds may also be set for different operation scenarios or performance requirements of the electronic device 100. For example, for a game scene with a high frame rate and a high change speed, the performance requirement is high, and the preset load threshold is small; for an application scenario 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 requirements and then determine a load threshold corresponding to the current performance requirements. For example, the electronic device 100 may determine the current performance requirement according to the currently running application, or may determine the current performance requirement based on other ways, which is not limited thereto.

In some embodiments, the electronic device 100 may also determine the load threshold by periodically obtaining a second load, which is the number of commands for accessing the internal memory. For example, the obtained second load may be the total number of commands for accessing the internal memory in the second interval, or may be the number of commands for accessing the internal memory at a certain time in the second interval. The relevant description may refer to 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.

And acquiring the duration of the period of the second load as a second interval. The second interval may be different from or the same as the first interval. In the embodiment of the present application, the second interval may be 1ms, 3ms, 5ms, 10ms, 16ms, 20ms, or the like. It should be noted that, 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; but may be 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 (which may be the second load) acquired at every first interval (or the second interval), and may determine the target frequency based on the first load (which may be the second load) acquired at every first interval (or the second interval), thereby helping to reduce the number of sampling times of the electronic device, and further helping to reduce the power consumption of the electronic device. Illustratively, the second interval is preset in the electronic device 100, for example, 1ms, 5ms, 3ms, 10ms, and so on. As another example, the electronic device 100 presets different time intervals, so that the electronic device 100 may 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 where the high frame rate changes at a high speed (e.g., a scene where the electronic device 100 runs a game), the second interval may be set to a smaller duration of 1ms, 2ms, or the like. For scenarios where the read/write requirements of the internal memory are low (e.g. scenarios where the electronic device 100 runs a clock, a calendar, a telephone), 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 to conserve power consumption while meeting performance requirements.

In still other embodiments, electronic device 100 may also determine the second interval based on the second load. The electronic device 100 may start acquiring the second load, and may adopt the default second interval because the number of acquired second loads is small and the performance requirement of the electronic device 100 cannot be identified. For example, the default second interval may be determined by referring to the related description of presetting the second interval. After the electronic device 100 acquires a sufficient number of second loads, the electronic device 100 may determine the second interval according to the acquired second loads. In some embodiments, the electronic device 100 determines the load threshold according to a plurality of second loads obtained within the first time period. The first time period may be preset or determined based on a preset policy. For example, the electronic device 100 may determine the second interval according to a plurality of second loads acquired in the first duration every first duration. As another example, the electronic device 100 may further determine the second interval according to a plurality of second loads acquired within the first duration in response to a triggering event (e.g., a performance requirement, etc.). For example, the first time period may be 10min, 20min, etc. The first duration may be variable or fixed. For example, as shown in fig. 7, the electronic device 100 acquires the second loads at every second interval 1 within the first duration 1, and if the second interval determined by the electronic device 100 based on the 5 second loads acquired within the first duration 1 is the second interval 2, the electronic device 100 acquires the second loads at every second interval 2 from the time t 4. When the electronic apparatus 100 determines the second interval every first duration, as shown in fig. 7, the electronic apparatus 100 determines the second interval according to the acquired 4 second loads within the first duration 2. If the electronic device 100 determines that the second interval is the second interval 3 according to the 4 second loads acquired within the first duration 2, when the second interval 3 is equal to the second interval 2, the electronic device 100 continues to acquire the second load using the second interval 2 from the time 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 using the second interval 3 from the time t 8. For another example, when the electronic device 100 responds to the trigger event and determines the second interval according to the plurality of second loads acquired within the first duration, as shown in fig. 7, if the electronic device 100 responds to the trigger event at time T, the second interval is determined to be the second interval 2 according to the 4 second loads acquired within the first duration 2.

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

the electronic device 100 extracts a first feature value according to the plurality of second loads acquired within the first duration. And then determining the interval corresponding to the first characteristic value as a second interval from the preset corresponding relation between the 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, a threshold value corresponding to the first feature value as the load threshold from a preset correspondence between the feature value and the threshold. It should be noted that, according to the second characteristic value, the electronic device 100 may further determine the load threshold from a preset corresponding relationship between the characteristic value and the threshold. And 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 acquired periodically by the electronic device 100, or acquired by event triggering of the electronic device 100, which is not limited in this respect. When the third load is periodically acquired by the electronic device 100, the duration of the period in which the electronic device 100 acquires the third load may be different from the first interval and the second interval, and a manner of determining the duration of the period of the third load may refer to a manner of determining the second interval. The explanation of the third load can be referred to the explanation of the first load. For example, 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 the electronic device 100 determines the second interval, it is determined whether the determined second interval and/or the load threshold meet the performance requirement of the current operating scenario of the electronic device 100. For example, the performance requirement may be frame rate, latency, etc. If not, the electronic device 100 adjusts the second interval according to a preset first policy, and/or adjusts the load threshold according to a 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, whether the reduced second interval and/or the load threshold meet the performance requirement of the current operation scene of the electronic device 100 is continuously judged. Until the performance requirements are met. It should be noted that when the second interval and/or the load threshold is adjusted to the limit value and cannot be adjusted, the electronic device 100 may select the second interval and/or the load threshold with the optimal performance and power consumption from the adjustment process. Such that the electronic device 100 may update the setting of the second interval based on the newly determined second interval and/or update the setting of the load threshold according to 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 within 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, an interval corresponding to the first feature value as a second interval from a 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, a threshold value corresponding to the first feature value as the load threshold from a preset correspondence between the feature value and the 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 the 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 meet the delay requirement at the frame rate of 60fps, and if not, the performance detection module 404 sends the adjustment policy to the analysis module 403. For example, the adjustment strategy may include a first adjustment strategy, which may be to decrease the second interval, and/or a second adjustment strategy, which may be to decrease the load threshold. The ratio of decreasing the second interval and/or the ratio of decreasing the load threshold may be sent to the analysis module 403 by the performance detection module 404, or the analysis module 403 may decrease the second interval according to a preset first ratio and/or decrease the load threshold according to a preset second ratio, and then send the decreased second interval and/or the decreased load threshold to the performance detection module 404. A determination is made by the performance detection module 404 as to whether the reduced second interval and/or the reduced load threshold meets the current performance requirements of the electronic device 100. Until the analysis module 403 receives the notification of the performance detection being satisfied sent by the performance detection module 404, the analysis module 403 sends a second interval and/or a load threshold satisfying the performance detection to the storage controller 121. And the storage controller 121 updates the setting of the load threshold according to the determined load threshold, and/or the storage controller 121 sends the second interval to the statistics module 401, so that the statistics module 401 updates the setting of the second interval according to the determined second interval. It should be noted that, when the second interval and/or the load threshold cannot be adjusted continuously, the analysis module 403 may select the second interval and/or the load threshold at which the performance and the power consumption are optimal from the adjustment process, and send the selected second interval and/or the selected load threshold to the storage controller 121.

In addition, it should be noted that, a secondary load threshold may also be preset in the electronic device 100, and when the electronic device 100 uses a load threshold determined based on the obtained at least two second loads, if a frame drop event occurs during operation of the electronic device 100 and the electronic device 100 cannot continuously adjust the load threshold determined based on the obtained at least two second loads, the load threshold may be directly adjusted to the secondary load threshold, so that the electronic device 100 may quickly adjust the operating frequency of the internal memory to the highest frequency, and ensure performance of the system. The secondary load threshold may also include an upper frequency modulation threshold and a lower frequency modulation threshold, where when the first load is greater than the upper frequency modulation 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 lower frequency modulation 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 frequencies supported by the internal memory that is less than the highest frequency. In addition, the secondary load threshold may not be distinguished from the upper frequency modulation threshold and the lower frequency modulation threshold, and when the electronic device 100 sets the load threshold as the secondary 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 preset correspondence relationship between the 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. Illustratively, the duration of a frame may be 16.67 ms. E.g., 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 eigenvalues is less than the duration of one frame, e.g., 1ms, 5ms, etc. For another example, when the characteristic value indicates that the performance requirement of the electronic device does not substantially change within the duration of one frame, such as a high performance requirement, a medium performance requirement, or a low performance requirement, the duration of the sampling interval corresponding to the characteristic value may be the duration of one frame, or may be greater, such as 20 ms. Take 5 second loads collected during 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 duration 1, and is in a high performance requirement between the time t1 and the time t3, so that the size of the second load is greatly different in the first duration 1, in which case the first characteristic value extracted by the electronic device 100 is used to indicate that the performance requirement of the electronic device 100 changes in the first duration 1. Thus, the second interval corresponding to the first characteristic value determined by the electronic device 100 is less than the first duration 1, for example, the first duration 1 is a duration of one frame, and the second interval may be, for example, 1ms, 5ms, and so on. Thereby helping to shorten the interval for adjusting the operating frequency of the internal memory.

For example, the first characteristic value may be a maximum value or a minimum value of the number of two or more commands for accessing the internal memory, an average value of the number of two or more commands 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 the number of the plurality of commands for accessing the internal memory in the first time period, and then determine a characteristic value corresponding to the performance requirement of the electronic device 100 according to a corresponding relationship between the performance requirement and the characteristic 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 time-dependent curve of the number of commands for accessing the internal memory according to the plurality of second loads for the first time period. Electronic device 100 may determine the performance requirements of electronic device 100 based on a number of commands to access internal memory versus time. In addition, the algorithm for extracting the first feature value is not particularly limited in the embodiment of the present application.

For example, in the preset correspondence relationship between the 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 changes from a low performance requirement to a high performance requirement, or from the high performance requirement to the low performance requirement, the threshold corresponding to the feature value is smaller, and the like. For another example, when the characteristic value indicates that the performance requirement of the electronic device does not substantially change within the duration of one frame, such as a continuous high performance requirement, the threshold corresponding to the characteristic value may be a minimum value. For another example, if the characteristic value indicates that the performance requirement of the electronic device continues to be a low performance requirement for the duration of one frame, the threshold corresponding to the characteristic value may be a maximum value, and so on.

It should be noted that, in the embodiment of the present application, the load threshold may include an upper frequency modulation threshold and a lower frequency modulation threshold, so as to help reduce the possibility of the 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, the correspondence between the magnitude relationship 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 the 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 is 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 in addition, a frequency of 830MHz is supported. Taking the upper frequency modulation threshold and the lower frequency modulation threshold included in the load threshold as an example, if the electronic device 100 is pre-configured with two sets 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 load and the load threshold 1 and the frequency is shown in table 2, and the table of the correspondence between the load and the load threshold 2 and the frequency is shown in table 3.

TABLE 2

Load and load threshold 1 magnitude relationship	Frequency of
The load is larger than 32000	830MHz
The load is less than 29000	415MHz

TABLE 3

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

In the above scenario, when the first load is 40000 and the load threshold is 1, the target frequency determined by the electronic device 100 is 830 MHz. When the first load is 10000 and the load threshold is 1, the target frequency determined by the electronic device 100 is 415 MHz. When the first load is 30000 and the load threshold is load threshold 1, if the operating frequency of the internal memory currently set by the electronic device 100 is 830MHz, the determined target frequency is 830 MHz. When the first load is 30000 and the load threshold is load threshold 1, if the operating frequency of the internal memory currently set by the electronic device 100 is 415MHz, the determined target frequency is 415 MHz. However, when the first load is 30000 and the load threshold is load threshold 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 830 MHz.

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.

If the operating frequency of the internal memory currently set by the electronic device 100 is different from the target frequency, the electronic device 100 adjusts the operating 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 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. For another example, if the operating frequency of the internal memory currently set by the electronic device 100 is 2133MHz, and if the determined target frequency is 415MHz, the operating frequency of the internal memory is adjusted to 415MHz in the electronic device 100.

In the embodiment of the application, the setting mode of the first interval and the second interval may be set based on the performance requirement of the electronic device, for example, when the number of commands for accessing the internal memory is higher, the second interval may be smaller, so that the determined load threshold better meets the performance requirement of the current operation scenario of the electronic device, and the electronic device may adjust the operating frequency of the internal memory in time. For example, as shown in fig. 8, the load threshold of the electronic device 100 includes an upper frequency modulation threshold 1 and a lower frequency modulation threshold 1, where the upper frequency modulation threshold 1 and the lower frequency modulation threshold 1 are determined based on the second load, and can meet the current performance requirement of the electronic device 100. Therefore, when the method for adjusting the working frequency of the internal memory is adopted, the 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 first load can be acquired at the time t1 and the time t2, the upper frequency modulation threshold is greater than the upper frequency modulation threshold 1 when the first load is acquired at the time t1, and the electronic device 100 adjusts the operating frequency of the internal memory to the high frequency Fre at the time t1_highAnd the electronic device 100 adjusts the operating frequency of the internal memory to the high frequency Fre at time t2 when the first load acquired at time t2 is less than the lower tuning threshold_low. The internal memory of the electronic device 100 thus operates at the high frequency Fre between times t1 and t2_highAnd internal memory after time t2The memory works at a low frequency, and intra-frame frequency modulation is realized, so that when the electronic device 100 has a large number of commands for accessing the internal memory, the internal memory works at a high frequency, and when the electronic device 100 has a small number of commands for accessing the internal memory, the internal memory works at a low frequency, which is beneficial to ensuring normal operation of the electronic device 100 and reducing power consumption of the device.

A certain game application at a frame rate of 60fps runs on a cell phone model number of Hua Mate10 and an internal memory of DDR, wherein the DDR supports frequencies of 415MHz, 830MHz, 1244MHz and 1866 MHz.

When the DDR working frequency is adjusted based on the bandwidth size of a memory controller for accessing a memory, wherein the statistical cycle of the bandwidth size is 16ms during frequency modulation, and 20ms during frequency modulation; the frequency modulation interval is 16ms, when the bandwidth size is larger than 7.3GB/s, the working frequency of the DDR is adjusted to 1244MHz, however, under the scene of 60fps frame rate, the 7GB/s bandwidth works at 830M frequency, the game frame rate falls below 50, and the game experience is seriously affected, so the performance of the mobile phone is ensured by forcibly increasing the working frequency of the DDR, through tests, in the process of running the game at the 60fps frame rate, the DDR 85% of time works at the frequency of 1244MHz, and 15% of time works at the frequency of 830 MHz. The total power consumption of the mobile phone is 500mw, wherein the power consumption of the mobile phone when the inner DDR works at the frequency of 1244MHz is 436mw, and the power consumption of the mobile phone when the DDR works at the frequency of 830MHz is 64 mw.

However, when the frequency modulation method according to the embodiment of the present application is adopted, where 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, when the frame rate is sufficient, DDR 55% 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 415 MHz. The total power consumption of the electronic equipment is reduced to 438.4mw, wherein the power consumption of the DDR is 282mw when the working frequency of the DDR is 1244MHz, the power consumption of the DDR is 64mw when the working frequency of the DDR is 830MHz, and the power consumption of the DDR is 92.4mw when the working frequency of the DDR is 415 MHz.

For example, as shown in a in fig. 9, the operating frequency of the internal memory varies with time in the case of a certain game application program with a frame rate of 60fps being executed by the electronic device. It can be seen from the graph shown in fig. 9 that the duration of the adjustment interval of the operating frequency of the internal memory is changed, and the operating frequency of the internal memory is changed correspondingly with the change of time. In fig. 9, B is a schematic diagram showing the change of power consumption with time in a scenario where the electronic device runs a certain game application at a frame rate of 60 fps. It can be seen from B in fig. 9 and a in fig. 9 that the larger the operating frequency of the internal memory is, the larger the power consumption of the electronic device is, and thus the trend of the change in the power consumption of the electronic device with time is the same as the trend of the change in the operating frequency of the internal memory with time.
