[0024] The following will be combined with the drawings of the embodiments of the present application to clearly describe the technical solutions of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] In response to the problems arising from related technologies, the embodiments of the present application provide a method, device, electronic device and readable storage medium for adjusting an operating frequency, which can not only ensure performance but also not affect the battery life of the electronic device in a frequency increase scenario.

[0027] The operating frequency adjustment method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0028] The technical terms involved in the embodiments of the present application are explained below:

[0029] Boost frequency, that is, frequency increase, refers to a strategy in the CPU frequency regulation algorithm, that is, before detecting that performance demand is about to arrive, performance demand such as user operation, the CPU frequency is increased to a higher level in advance to ensure that the system can respond quickly and maintain smoothness, aiming to avoid freezes or delays at peak performance demand, thereby improving the user experience.

[0030] How Boost frequency works: By monitoring the current CPU load, user operations, etc., it predicts upcoming performance needs. Once a performance need is predicted, the system will immediately increase the CPU frequency to a preset higher value (Boost frequency), rather than waiting until the load increases and then gradually increasing the frequency. During performance needs, the CPU runs at a higher frequency to ensure that the system can respond quickly to user operations and avoid lags. Once the performance need ends, the system will restore the CPU frequency to normal levels to save power and extend battery life.

[0031] By increasing the frequency in advance, you can significantly reduce the delay and lag during user operations and improve fluency. Be prepared before high-load tasks arrive to ensure that the system can respond quickly.

[0032] However, higher CPU frequencies consume more power and may reduce battery life. High frequency operation increases CPU heat and may require a better cooling system to maintain stable operation.

[0033] Boost frequency will appear in the following application scenarios:

[0034] When launching a game or performing complex operations, the CPU frequency is increased in advance to ensure a smooth gaming experience. When switching applications or performing multitasking, the CPU frequency is increased in advance to ensure that the system can respond quickly.

[0035] Therefore, Boost frequency is a strategy to optimize performance and user experience by increasing the CPU frequency in advance, which is especially suitable for application scenarios that require fast response and high performance.

[0036] Cluster: refers to a cluster of CPUs. Multiple physical CPUs are combined to form a processor cluster, that is, the processor cluster includes multiple processors. The multiple processors included in the processor cluster share the same frequency and voltage, but each CPU in the processor cluster can enter the idle state and working state independently.

[0037] Idle rate: refers to the proportion of CPU being idle over a period of time.

[0038] Figure 1 A flowchart of a method for adjusting operating frequency provided in an embodiment of the present application.

[0039] like Figure 1 As shown, the working frequency adjustment method may include steps 110 to 130, and the method is applied to the working frequency adjustment device, as shown below:

[0040] Step 110, obtaining a current idle rate, a current load parameter value, a target idle rate, and a historical frequency boost coefficient of the processor cluster; the historical frequency boost coefficient is a coefficient when a historical frequency boost operation is performed on the processor cluster;

[0041] Current idle rate: The ratio of the time that the processor cluster is currently idle to the total time. The current idle rate is used to evaluate the utilization of the processor cluster and help determine whether the operating frequency needs to be adjusted to improve performance or reduce power consumption.

[0042] Current load parameter value: The current load of the processor cluster, usually expressed in parameters such as CPU usage and task queue length. The current load parameter value is used to evaluate the current workload of the processor cluster and help determine whether the operating frequency needs to be adjusted to match the load requirements.

[0043] Target idle rate: The target idle rate of the processor cluster, that is, the proportion of time that the processor cluster is expected to be idle under ideal conditions. It is used to set the performance and power consumption balance point of the processor cluster, helping to maintain optimal performance and energy efficiency under different load conditions.

[0044] Historical frequency boost coefficient: The coefficient used when the processor cluster performs historical frequency boost operations, reflecting the frequency boost of the processor cluster in the past period of time. The frequency boost operation refers to increasing the operating frequency of the processor cluster to a higher level to improve the performance of the processor.

[0045] The historical frequency boost factor is used to help the system determine the current frequency boost factor, thereby adjusting the operating frequency of the processor cluster.

[0046] The frequency boost factor is a numerical value that indicates the ratio by which the operating frequency of the processor cluster should be increased. It is a relative value that indicates the increase relative to the current operating frequency. The frequency boost factor indicates the operating frequency that the processor cluster should increase under the current load conditions.

[0047] The current frequency boost coefficient is calculated based on the current idle rate, the target idle rate and the historical frequency boost coefficient. The operating frequency of the processor cluster is adjusted based on the current frequency boost coefficient and the current load parameter value. After the frequency boost operation is completed, the historical frequency boost coefficient is updated for use in the next frequency boost operation.

[0048] By monitoring the operating status of the processor cluster, the current idle rate, current load parameter value, target idle rate and historical frequency increase coefficient are obtained. These data are used to evaluate the current status and historical adjustment strategy of the processor cluster, providing a basis for subsequent frequency adjustment.

[0049] By obtaining these parameters, we can fully understand the current status and historical adjustment of the processor cluster, and provide accurate data support for subsequent frequency adjustments.

[0050] Step 120, determining a current frequency boost coefficient according to the current idle rate, the target idle rate and the historical frequency boost coefficient;

[0051] Current frequency boost factor: A factor determined based on the current idle rate, target idle rate, and historical frequency boost factor. It is used to adjust the operating frequency of the processor cluster and is used to dynamically adjust the operating frequency of the processor cluster to adapt to current load requirements and performance targets.

[0052] The current frequency boost factor is calculated based on the difference between the current idle rate and the target idle rate, combined with the historical frequency boost factor. For example, if the current idle rate is lower than the target idle rate, it means that the processor cluster load is high and the operating frequency may need to be increased; conversely, if the current idle rate is higher than the target idle rate, it means that the processor cluster load is low and the operating frequency may need to be reduced.

[0053] By dynamically calculating the current frequency boost factor, the operating frequency can be flexibly adjusted according to the actual load of the processor cluster to achieve the best balance between performance and energy efficiency.

[0054] Step 130: Adjust the operating frequency of the processor cluster according to the current frequency boost coefficient and the current load parameter value.

[0055] According to the calculated current frequency boost coefficient and current load parameter value, the operating frequency of the processor cluster is adjusted. For example, if the current frequency boost coefficient is high and the current load parameter value is high, it means that the processor cluster needs higher performance, and the operating frequency of the processor cluster will be increased; conversely, if the current frequency boost coefficient is low and the current load parameter value is low, it means that the processor cluster load is low, and the operating frequency of the processor cluster will be reduced.

[0056] By dynamically adjusting the operating frequency of the processor cluster, the performance and energy efficiency of the processor cluster can be optimized according to actual load requirements, avoiding power consumption waste caused by too high frequency or insufficient performance caused by too low frequency.

[0057] As a result, the operating status of the processor cluster can be monitored in real time, the current frequency boost factor can be dynamically calculated based on the current idle rate, target idle rate and historical frequency boost factor, and the operating frequency of the processor cluster can be flexibly adjusted based on the current frequency boost factor and current load parameter value. This not only helps maintain optimal performance and energy efficiency under different load conditions, but also avoids performance waste or energy efficiency loss caused by improper frequency adjustment.

[0058] In a possible embodiment, obtaining the current idle rate of the processor cluster includes:

[0059] Within a preset time period, the idle rates of multiple processors associated with the processor cluster are obtained; the operating frequencies and operating voltages of the multiple processors associated with the processor cluster are the same;

[0060] The minimum idle rate among the idle rates of the plurality of processors is determined as the current idle rate of the processor cluster.

[0061] Preset time period: A fixed time interval or cycle set when obtaining the idle rate of the processor cluster. It is used to ensure that the idle rate data obtained is representative and can reflect the average state of the processor cluster over a period of time.

[0062] Processor: Definition: In a multi-core or processor cluster, each independent processing unit is called a processor. It is used to process tasks in parallel to improve computing power and efficiency.

[0063] Idle rate: The proportion of the processor's idle time to the total time. It is used to evaluate the processor utilization and help determine whether the operating frequency needs to be adjusted to improve performance or reduce power consumption.

[0064] During a preset time period, the idle rate of each processor is obtained by monitoring its operating status. The operating frequency and operating voltage of multiple processors associated with a processor cluster are the same, which means that they are in the same cluster and share the same frequency and voltage settings.

[0065] By obtaining the idle rates of multiple processors, we can fully understand the utilization of the entire Cluster and provide accurate data support for subsequent frequency adjustments.

[0066] The minimum idle rate is selected from the idle rates of multiple processors as the current idle rate of the entire processor cluster. The reason for selecting the minimum idle rate is that if the idle rate of a processor is low, it means that the load of the node is high, and the operating frequency of the entire cluster may need to be increased to meet performance requirements.

[0067] By selecting the minimum idle rate as the current idle rate, the actual load of the processor cluster can be more accurately reflected, avoiding insufficient overall performance due to the high load of a certain node.

[0068] The idle rate of each processor is periodically obtained through the system clock. For each processor, the idle rate of the processor in the most recent multiple cycles is selected, and the average or maximum value of the idle rate of the processor in the multiple cycles is used as the idle rate of the processor. The multiple cycles, for example, 3 cycles or 5 cycles, may have a cycle length of 4 milliseconds (ms).

[0069] In the same cluster, the smallest idle rate among the processor idle rates is selected as the CPU idle rate of this cluster, that is, the current idle rate of the processor cluster.

[0070] As a result, the idle rates of multiple processors associated with the processor cluster can be monitored within a preset time period, and the minimum idle rate among the idle rates of multiple processors can be determined as the current idle rate of the processor cluster. This not only helps to fully understand the actual load of the processor cluster, but also provides accurate data support for subsequent frequency adjustments, ensuring that the processor cluster maintains optimal performance and energy efficiency under different load conditions.

[0071] In a possible embodiment, step 120 may specifically include the following steps:

[0072] Determine a ratio of the current idle rate to the target idle rate;

[0073] A current frequency boost coefficient is determined according to the historical frequency boost coefficient and the proportional value.

[0074] Since the target idle rate is a set target idle rate of a processor cluster, that is, the time ratio of the processor cluster in an ideal idle state, for example, if the idle rate of the CPU is controlled at about 20%, the target idle rate is 20%.

[0075] For example, Figure 3 As shown, when the CPU idle rate is greater than 20%, it means that the CPU is relatively idle and the tasks on the CPU are relatively few or light. At this time, the CPU boost frequency should be reduced, as shown in cycle 3; when the CPU idle rate is less than 20%, it means that the CPU is relatively busy and the tasks on the CPU are relatively many or heavy. At this time, the CPU boost frequency should be increased, as shown in cycle 1.

[0076] Ratio value: The ratio between the current idle rate and the target idle rate. It is used to evaluate the gap between the current idle rate and the target idle rate, and to help determine whether the frequency increase factor needs to be adjusted.

[0077] Calculate the ratio between the current idle rate and the target idle rate. The ratio reflects the difference between the current idle rate and the target idle rate. The smaller the ratio, the lower the current idle rate and the higher the load, which may require a higher frequency boost factor.

[0078] By calculating the ratio value, the gap between the current idle rate and the target idle rate can be quantified, providing a basis for subsequent frequency boost factor adjustment.

[0079] The current frequency boost coefficient is determined based on the historical frequency boost coefficient and the calculated ratio value. The current frequency boost coefficient can be calculated using the following formula:

[0080] Current frequency boost coefficient = historical frequency boost coefficient × ratio value;

[0081] If the ratio value is small, it means that the current load is high, and the current frequency boost coefficient will increase accordingly to increase the operating frequency of the processor cluster; conversely, if the ratio value is large, it means that the current load is low, and the current frequency boost coefficient will decrease accordingly to reduce the operating frequency of the processor cluster.

[0082] Therefore, by combining the historical frequency boost coefficient and the proportional value, the current frequency boost coefficient can be dynamically adjusted to adapt to the current load demand and performance target, achieving the best balance between performance and energy efficiency.

[0083] In a possible embodiment, step 130 may specifically include the following steps:

[0084] Determining a target boost frequency according to the current load parameter value;

[0085] Determining a current boost frequency according to the current frequency boost coefficient and the target boost frequency;

[0086] The operating frequency of the processor cluster is adjusted according to the current boost frequency.

[0087] Target frequency boost: The target frequency boost value determined based on the current load parameter value is used to guide the adjustment of the operating frequency of the processor cluster. It is used to set the ideal operating frequency of the processor cluster under the current load condition, helping to maintain optimal performance and energy efficiency under different load conditions.

[0088] Current boost frequency: The actual frequency boost value determined based on the current frequency boost coefficient and the target boost frequency, used to adjust the operating frequency of the processor cluster. It is used to dynamically adjust the operating frequency of the processor cluster to adapt to the current load requirements and performance goals.

[0089] The target boost frequency is determined based on current load parameter values, such as CPU usage and task queue length, etc. The target boost frequency can be calculated using a preset load-frequency mapping table or algorithm.

[0090] For example, if the current load parameter value is high, it means that the processor cluster is heavily loaded, and the target boost frequency will be increased accordingly; conversely, if the current load parameter value is low, it means that the processor cluster is lightly loaded, and the target boost frequency will be decreased accordingly.

[0091] By determining the target boost frequency, the ideal operating frequency can be set according to the current load conditions, providing a basis for subsequent frequency adjustments.

[0092] The current boost frequency is calculated based on the current frequency boost coefficient and the target boost frequency. The current boost frequency can be calculated using the following formula:

[0093] Current boost frequency = target boost frequency × current frequency boost coefficient;

[0094] The current boost frequency reflects the actual frequency value that needs to be adjusted. Combined with the current frequency boost coefficient, the operating frequency of the processor cluster can be adjusted more accurately.

[0095] By combining the current frequency boost coefficient and the target boost frequency, the current boost frequency can be dynamically calculated to adapt to the current load demand and performance target to achieve the best balance between performance and energy efficiency.

[0096] The operating frequency of the processor cluster is adjusted according to the calculated current boost frequency. The adjustment method may be to directly set the frequency of the processor cluster or to adjust it through a dynamic voltage frequency adjustment technology.

[0097] For example, if the current boost frequency is high, the operating frequency of the processor cluster will be increased; conversely, if the current boost frequency is low, the operating frequency of the processor cluster will be reduced.

[0098] By dynamically adjusting the operating frequency of the processor cluster, the performance and energy efficiency of the processor cluster can be optimized according to actual load requirements, avoiding power consumption waste caused by too high frequency or insufficient performance caused by too low frequency.

[0099] Therefore, by being able to determine the target boost frequency according to the current load parameter value, calculate the current boost frequency in combination with the current frequency boost coefficient, and dynamically adjust the operating frequency of the processor cluster according to the current boost frequency, this not only helps maintain optimal performance and energy efficiency under different load conditions, but also avoids performance waste or energy efficiency loss caused by improper frequency adjustment.

[0100] The step of determining the target boost frequency according to the current load parameter value mentioned above includes:

[0101] Acquire a preset corresponding relationship, wherein the preset corresponding relationship includes a plurality of sets of corresponding preset load parameter values ​​and preset boost frequencies;

[0102] According to the preset corresponding relationship, a target boost frequency corresponding to the current load parameter value is determined.

[0103] Preset correspondence: The correspondence between the preset load parameter value and the boost frequency, usually expressed in a table or algorithm form. It is used to guide the determination of the target boost frequency under different load conditions and help maintain the best performance and energy efficiency under different load conditions.

[0104] Preset load parameter value: In the preset correspondence, the pre-set load parameter value is used to compare with the actual load parameter value. It is used to determine the target boost frequency to help maintain the best performance and energy efficiency under different load conditions.

[0105] Preset boost frequency: In the preset correspondence, the preset boost frequency is used to compare with the boost frequency corresponding to the actual load parameter value. It is used to determine the target boost frequency to help maintain optimal performance and energy efficiency under different load conditions.

[0106] Obtain the correspondence between the preset load parameter value and the boost frequency. The preset correspondence is usually expressed in a table or algorithm form, including multiple sets of corresponding preset load parameter values ​​and preset boost frequencies. For example, the preset correspondence can be a table, in which each row contains a load parameter value and a corresponding boost frequency.

[0107] By obtaining the preset corresponding relationship, the corresponding target boost frequency can be quickly found according to the current load parameter value, providing a basis for subsequent frequency adjustment.

[0108] Current load parameter value: You can use the WALT or PELT algorithm for calculation. The following uses the WALT algorithm as an example to explain how to calculate the CPU load. The WALT algorithm is a new algorithm that tracks the CPU utilization of the process in units of time windows and calculates the running time of the next window. The time window is a configurable value, and the default value is 20 milliseconds.

[0109] The WALT algorithm calculates the CPU running time within a statistical window, which is called WALT time, also known as WALT CPU running time. Assuming that in an ARM system-on-chip (System on Chip, ARM SoC) with a big-small core architecture, the maximum frequency of the small-core CPU is 1GHZ, the maximum frequency of the large-core CPU is 2GHZ, and the computing power (Instructions Per Cycle, IPC) of the large core is twice that of the small core, then the time to run a statistical window at the highest frequency on the large core is called 100% WALT CPU time, that is, 20ms.

[0110] If it runs at 1 GHZ for 10 ms on a small-core CPU, its WALT CPU time can be calculated using the above formula. That is, although it runs at 1 GHZ for 10 ms on a small-core CPU, it only runs for 2.5 ms using the WALT algorithm.

[0111] Load_avg=walt_time / windows*1024;

[0112] Load_avg represents the CPU load calculated using the WALT algorithm, that is, the current load parameter value;

[0113] Windows represents the time window for WALT algorithm calculation;

[0114] 1024 normalizes the calculation results to 1024 and unifies the calculation units.

[0115] According to the current load parameter value, the corresponding preset boost frequency is searched in the preset correspondence. If the current load parameter value exists in the preset correspondence, the corresponding preset boost frequency is directly used as the target boost frequency; if the current load parameter value does not exist in the preset correspondence, the upper value is taken, which means selecting the boost frequency corresponding to the closest load parameter value larger than the current load parameter value. That is, if the current load parameter value does not exist in the preset correspondence, the closest load parameter value larger than the current load parameter value is selected in the preset correspondence. The boost frequency corresponding to the selected load parameter value is used as the target boost frequency.

[0116] For example, the current load parameter value is 620. When searching for 620 in the preset correspondence, it is found that it does not exist. The closest load parameter value greater than 620 is selected, that is, 680. The boost frequency 1.8 GHz corresponding to 680 is used as the target boost frequency.

[0117] The preset corresponding relationship may be as shown in Table 1:

[0118] Table 1

[0119] CPU freq (CPU_target_freq) CPU util(load_avg) 3Ghz 1024 2.5Ghz 950 2Ghz 850 1.8Ghz 680 1.5Ghz 600 1.2Ghz 550 1Ghz 480 0.8Ghz 450

[0120] By searching or calculating the target boost frequency, the ideal operating frequency can be set according to the current load parameter value, providing a basis for subsequent frequency adjustment.

[0121] Therefore, by being able to obtain the correspondence between the preset load parameter value and the boost frequency, and searching or calculating the target boost frequency in the preset correspondence according to the current load parameter value, this not only helps to set the ideal operating frequency under different load conditions, but also provides accurate data support for subsequent frequency adjustments, ensuring that the processor cluster maintains optimal performance and energy efficiency under different load conditions.

[0122] In an embodiment of the present application, the current idle rate, current load parameter value, target idle rate and historical frequency boost coefficient of the processor cluster are obtained, and the current frequency boost coefficient is determined according to the current idle rate, target idle rate and historical frequency boost coefficient. The historical frequency boost coefficient is the coefficient when the processor cluster performs a historical frequency boost operation. In this way, according to the difference between the current idle rate and the target idle rate, combined with the historical frequency boost coefficient, the current frequency boost coefficient can be determined according to the actual load of the processor to achieve the best performance balance. The operating frequency of the processor cluster is adjusted according to the current frequency boost coefficient and the current load parameter value, and the performance and energy efficiency of the processor can be optimized according to the actual load requirements, avoiding power consumption waste caused by too high a frequency or insufficient performance caused by too low a frequency, which not only ensures performance, but also does not affect the battery life of the electronic device.
