[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] The Intelligent Power Allocation (IPA) algorithm is a software algorithm developed by ARM that complies with the temperature control related modules under the Linux kernel. It aims to maximize performance under the condition of temperature control effect. The IPA algorithm is based on the following theory: the temperature of the system on a chip (SOC) is positively correlated with the power consumption. The higher the power consumption, the higher the temperature. The power consumption of the SOC is mainly consumed by the IP cores on it, such as the central processing unit (CPU) and the graphics processing unit (GPU). Therefore, the purpose of controlling the temperature can be achieved by controlling the power consumption of the SOC. By reasonably allocating power consumption among various IP cores, the performance under temperature control can be maximized. Based on the above theory, the implementation of the IPA algorithm includes two core functions: temperature closed-loop control based on proportional-integral-derivative control (PID) and energy allocation algorithm (Power Allocator, PA). For IPA, the main input is temperature and the performance requirements of each IP core. The temperature can come from SOC or the board temperature of the IP core. IPA uses the temperature difference between the collected temperature and the target control temperature as the control input. The performance requirements of each IP core are calculated by the current load, and then converted into energy requirements as the input of IPA using the <frequency, voltage> pair (Operating Performance Point, OPP) and energy model (Energy Model, EM) supported by SOC. The output of IPA is the actual allocated energy, which is then converted into performance indicators (such as maximum operating frequency) through OPP and EM. Such a cycle finally realizes the temperature control of the hardware. Among them, the PID temperature closed-loop control of the IPA algorithm has its control input as the difference e between the target temperature and the current temperature. The cumulative summation calculated by proportional, integral, and differential calculations and then added to sustainable_power is the maximum power consumption value allowed at the current temperature. Sustainable_power refers to the maximum power consumption value allowed under the condition of ensuring that the target temperature target_temerature is met. The control function of PID can be expressed as the following formula:

[0029] P max =k p *e+k i *integral err +k d *diff err +sustainable_power,

[0030] In the formula, k p ,k i ,k d is the weighting coefficient, P max is the actual energy distributed, integral err Indicates the integral, diff err Represents differential. It can be seen from the above formula that the energy calculation stage of actual allocation is calculated by the difference between the target temperature and the current temperature using the PID algorithm, which has nothing to do with the load of the current performance requirement and does not take into account the dimension of short-term performance requirements. If there is a protruding short-term heavy load demand and exceeds the total energy allocation, because the total allocated energy has been determined according to the temperature difference in the energy allocation stage, at this time, it can only be subdivided according to the performance requirements of each IP core according to the determined total energy, but it cannot solve the problem of insufficient total energy, and may cause the chip to have a short-term performance problem. Based on this, the embodiments of the present application provide an energy value determination method, device, electronic device and computer-readable storage medium, which can avoid the problem of insufficient short-term performance of the chip.

[0031] In one embodiment, Figure 1 As shown, a method for determining an energy value is provided. This embodiment uses the method applied to an electronic device as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including an electronic device and a server, and is implemented through the interaction between the electronic device and the server. In this embodiment, the method includes the following steps:

[0032] S201, determining the actual energy value required to meet the chip performance according to the chip's operating frequency and load information.

[0033] Among them, the operating frequency of the chip is related to the speed at which it processes data. The operating frequency of the chip is the main indicator to measure the operating speed of the chip. The load information of the chip refers to the statistical information of the sum of the number of processes being processed and waiting to be processed by the chip within a period of time. Optionally, in this embodiment, the electronic device can call the relevant interface of the Android system kernel layer to obtain the operating frequency and load information of the chip. Optionally, the energy value in this application can be the power consumption value of the chip, or it can also be the computing power of the chip, etc., which is not limited in this embodiment.

[0034] Optionally, in this embodiment, the electronic device can determine the actual energy value required to meet the chip performance through an energy model (EM) according to the operating frequency and load information of the chip. It can be understood that the actual energy value required to meet the chip performance in this embodiment is determined according to the operating frequency and load information of the chip. When the operating frequency and load information of the chip change, the actual energy value determined to meet the chip performance will also change. Therefore, the electronic device can accurately determine the actual energy value required to meet the chip performance in real time according to the operating frequency and load information of the chip.

[0035] S202, determining a target energy value allocated to the chip according to the actual energy value and the expected energy value; wherein the expected energy value is calculated according to a proportional-integral-differential control PID algorithm.

[0036] Among them, the proportional-integral-derivative control (PID) algorithm takes the difference between the target temperature and the current temperature as input, and adds the accumulated sum through proportional, integral, and differential calculations and then adds it to sustainable_power to obtain the maximum power consumption value allowed at the current temperature, that is, the expected energy value required to meet the chip performance is determined by the PID algorithm. Optionally, in this embodiment, the actual energy value determined may be greater than the expected energy value, or the actual energy value determined may be less than the expected energy value. This embodiment does not limit the size relationship between the actual energy value and the expected energy value.

[0037] Optionally, in this embodiment, the electronic device may determine the target energy value assigned to the chip based on the energy difference between the actual energy value and the expected energy value. For example, the electronic device may determine the target energy value assigned to the chip by adding the actual energy value to the energy difference, or the electronic device may determine the target energy value assigned to the chip by subtracting the energy difference from the actual energy value.

[0038] In the above energy value determination method, the actual energy value required to meet the chip performance can be determined according to the operating frequency and load information of the chip, and the expected energy value required by the chip can be calculated according to the proportional-integral-differential control PID algorithm, so that the target energy value allocated to the chip can be determined according to the determined actual energy value and the expected energy value. Since the expected energy value calculated according to the PID algorithm is not the only consideration in the process of determining the target energy value allocated to the chip, but the actual energy value required to meet the chip performance is also combined, it can ensure that the energy value allocated to the chip is the actual energy value required by the chip, thereby avoiding the problem of short-term performance deficiencies of the chip due to insufficient allocated energy value.

[0039] In the above scenario where the target energy value assigned to the chip is determined based on the actual energy value and the expected energy value, the electronic device can determine the target energy value assigned to the chip based on the comparison result between the actual energy value and the expected energy value. Figure 2 As shown, the above S202 includes:

[0040] S301, obtaining a comparison result between an actual energy value and an expected energy value.

[0041] Optionally, in this embodiment, the comparison result of the actual energy value and the expected energy value may be that the actual energy value is greater than the expected energy value, or that the actual energy value is less than or equal to the expected energy value. Optionally, in this embodiment, the electronic device may obtain the comparison result of the actual energy value and the expected energy value by obtaining the difference between the actual energy value and the expected energy value. For example, when the difference between the actual energy value and the expected energy value is greater than 0, it can be determined that the actual energy value is greater than the expected energy value, and when the difference between the actual energy value and the expected energy value is less than or equal to 0, it can be determined that the actual energy value is less than or equal to the expected energy value.

[0042] S302: Determine a target energy value allocated to the chip according to the comparison result.

[0043] Optionally, in this embodiment, as an optional implementation, if the comparison result between the actual energy value and the expected energy value is that the actual energy value is greater than the expected energy value, that is, the determined expected energy value cannot meet the performance requirements of the chip, then the electronic device can obtain the first adjusted energy value from the preset buffer pool, and determine the sum of the energy values ​​of the first adjusted energy value and the expected energy value as the target energy value allocated to the chip. Optionally, the above buffer pool can be set in the electronic device, or in a server connected to the electronic device, and this embodiment does not limit this.

[0044] Optionally, in this embodiment, as another optional implementation method, if the comparison result of the actual energy value and the expected energy value is that the actual energy value is less than or equal to the expected energy value, that is, the determined expected energy value has exceeded the performance requirements of the chip, and the actual energy value determined by the electronic device is an energy value sufficient to meet the chip performance, then the electronic device does not need to allocate the excess energy value to the chip. In this case, the electronic device can determine the above-mentioned determined actual energy value as the target energy value allocated to the chip.

[0045] In this embodiment, since the process of obtaining the comparison result of the actual energy value and the expected energy value is relatively simple, the comparison result of the actual energy value and the expected energy value can be quickly obtained, so that the target energy value assigned to the chip can be quickly determined based on the comparison result of the actual energy value and the expected energy value, thereby improving the efficiency of determining the target energy value assigned to the chip.

[0046] In the above scenario where the actual energy value is less than or equal to the expected energy value, the electronic device can also store the portion of the expected energy value that exceeds the actual energy value. When the actual energy value required to meet the chip performance is greater than the expected energy value calculated by the PID algorithm, part of the energy value can be taken from the stored energy value to make up for the current shortfall, thereby meeting the current short-term high-load performance requirements. Figure 3 As shown, the above method also includes:

[0047] S401: Determine a second adjusted energy value according to the actual energy value and the expected energy value.

[0048] Optionally, in this embodiment, the electronic device can obtain the energy difference between the expected energy value and the actual energy value, and determine the energy difference between the expected energy value and the actual energy value as the second adjustment capacity value; or, the electronic device can also determine the part that exceeds the actual energy value from the expected energy value based on the actual energy value, and determine the excess energy value as the second adjustment energy value.

[0049] S402: Store the second adjusted energy value into a preset buffer pool.

[0050] In this embodiment, the electronic device stores the energy value that exceeds the actual energy value in the expected energy value into a preset buffer pool. When the actual energy value required to meet the chip performance is greater than the expected energy value calculated by the PID algorithm, part of the energy value is taken out from the buffer pool to make up for the current shortage, thereby meeting the current short-term high-load performance requirements and improving the performance experience, while also achieving the expected temperature control purpose.

[0051] Optionally, in this embodiment, an energy threshold of the buffer pool can be pre-set, that is, the storage capacity of the buffer pool cannot exceed the energy threshold. As an optional implementation, before storing the determined second adjusted energy value in the preset buffer pool, the electronic device can determine whether the energy value in the buffer pool is greater than the above energy threshold. When it is determined that the energy value in the buffer pool is not greater than the energy threshold, that is, the energy value stored in the buffer pool has not reached the storage upper limit, the electronic device can store the second adjusted capacity value in the buffer pool; when it is determined that the energy value in the buffer pool is greater than the energy threshold, that is, the energy value stored in the buffer pool reaches the storage upper limit, the electronic device can discard the determined second adjusted capacity value and no longer store it in the buffer pool. It can be understood that since the energy threshold is pre-set in the above buffer pool, the short-term high performance energy demand can be compensated by this method. After the cached energy value in the buffer pool is used up, it can only be allocated according to the expected energy value calculated by the PID algorithm. In this way, it can not only meet the chip's short-term energy allocation shortage, but also avoid the problem of excessive energy allocation for continuous high performance load causing temperature rise beyond the control range.

[0052] In this embodiment, when the actual energy value required to meet the chip performance is less than or equal to the determined expected energy value, the electronic device can determine a second adjusted energy value in the expected energy value that exceeds the actual energy value based on the actual energy value and the expected energy value, so that the determined second adjusted energy value can be stored in a preset buffer pool. When the actual energy value required to meet the chip performance is greater than the expected energy value calculated by the PID algorithm, part of the energy value can be taken out from the buffer pool to make up for the current shortage, thereby meeting the current short-term high-load performance requirements and improving the performance experience, while also achieving the expected temperature control purpose.

[0053] In this embodiment, the calculation process of the expected energy value is described in detail. In one embodiment, the method further comprises: obtaining the expected energy value according to the difference between the current temperature of the chip and the target temperature and the PID algorithm.

[0054] In this embodiment, the PID algorithm is one of the earliest developed control strategies. The PID algorithm belongs to closed-loop control. The input can be the difference between the current temperature of the chip and the target temperature, and the output is the expected energy value required by the chip. For example, the expression of the PID algorithm can be as follows:

[0055] P max =k p *e+k i *int egral err +k d *diff err +sustainable_power,

[0056] Where, e is the difference between the target temperature and the current temperature, k p ,k i ,k d is the weighting coefficient, P max is the actual energy distributed, integral err Indicates the integral, diff err represents the differential, and sustainable_power refers to the maximum power consumption value allowed under the condition of ensuring that the target temperature target_temerature is met. It should be noted that the proportional term k p It can improve the response speed and steady-state accuracy of the PID algorithm, but excessive proportional control can easily lead to overshoot and oscillation of the PID algorithm, and simple proportional control cannot eliminate the steady-state error of the PID algorithm. p It can play a role in linear scaling of the control deviation e; the integral term is the accumulation of the temperature difference e, and the integral control term can start to eliminate the steady-state error; the differential control term is the changing trend of the temperature difference e, which has a certain predictive effect, can reduce the overshoot and improve the temperature control stability.

[0057] In this embodiment, the difference between the current temperature of the chip and the target temperature is used as the input of the PID algorithm to calculate the expected energy value required by the chip.

[0058] In this embodiment, the process of calculating the expected energy value required by the chip based on the difference between the current temperature of the chip and the target temperature and the PID algorithm is relatively simple. By obtaining the difference between the current temperature of the chip and the target temperature, the PID algorithm can be used to quickly calculate the expected energy value required by the chip, thereby improving the efficiency of calculating the expected energy value required by the chip.

[0059] In order to facilitate the understanding of those skilled in the art, Figure 4 As shown, the energy value determination method provided by the present application is described in detail below in combination with a complete embodiment:

If not, store the second adjusted energy value in the buffer pool.
