The relevant definitions of other terms will be given in the following description.

[0025] In the related art, when the CPU link frequency regulator of each platform performs frequency regulation, it performs frequency regulation by sampling the load through an independent module. Due to the independence between the decision-making working frequency and the CPU scheduling and frequency regulation module, the load change during CPU scheduling and frequency regulation fails to be synchronized with the sampling decision module of the CPU link frequency regulator in a timely manner, and the CPU link frequency regulator is not notified in a timely manner to adjust the decision frequency synchronously, which makes the link adjustment of the CPU link frequency regulator untimely, thus affecting the power consumption and performance during actual use. For example, when the load suddenly increases, there will be a freeze, and when the load suddenly decreases, there will be excess performance and excessive power consumption.

[0026] In order to solve the technical problems existing in the related art, the present application embodiment provides a dynamic voltage frequency adjustment method, see Figure 1 , Figure 1 It is a flow chart of a dynamic voltage and frequency adjustment method provided in an embodiment of the present application, and the method includes steps 101 to 103.

[0027] Step 101, monitor the state of the target CPU to obtain the target state of the target CPU.

[0028] In one embodiment, when the frequency of a CPU link is adjusted, load sampling and monitoring of the CPU status are used as a basis for adjustment to complete the frequency modulation processing of the CPU link, wherein the CPU link includes but is not limited to L3, LLC and DDR.

[0029] Specifically, during the processing, the state of the target CPU is monitored in real time to obtain the target state of the target CPU. Among them, the CPU utilization is mainly divided into user state, system state and idle state, which respectively represent the time when the CPU is in user state execution, the time when the system kernel executes, and the time when the idle system process executes, and the sum of the three is the total time of the CPU. In this application, the use state of the CPU is divided into a dormant state and other states, corresponding to the aforementioned CPU utilization, the dormant state is the idle state, and the other states are the user state and the system state.

[0030] For example, when the CPU is being used, whether it is used by the user to execute tasks or by the system to execute tasks, there will be an increase in load. When it is in an idle state, the load it requires will be smaller, and the dynamic voltage frequency required by the corresponding CPU link under different loads will also be different. Therefore, when adjusting the dynamic voltage frequency of the CPU link, the state of the target CPU is monitored, and the corresponding adjustment strategy is determined according to different states and actual load conditions.

[0031] Step 102, obtaining a target load of a target CPU, and obtaining a target link frequency of the target CPU according to the target load.

[0032] In one embodiment, when the frequency adjustment process is performed on the CPU link, the frequency adjustment process is usually performed based on the CPU load condition. Therefore, in each embodiment, when the frequency adjustment process is performed on the target CPU, the target load of the target CPU is obtained, and the current corresponding target link frequency is determined based on the obtained target load.

[0033] Exemplarily, when the target link frequency is obtained, it means that under the current load of the target CPU, the frequency of the corresponding CPU link needs to be adjusted to the target link frequency, so that the target CPU has better performance and usage effect.

[0034] Furthermore, when obtaining the target link frequency, it is determined according to the corresponding relationship between the load and the link frequency. Therefore, when obtaining the target link frequency, it includes: obtaining the target load of the target CPU, and obtaining the frequency modulation mapping table; querying and matching in the frequency modulation mapping table according to the target load to obtain the target link frequency corresponding to the target load.

[0035] Specifically, the frequencies of the CPU links of different CPUs under different loads can be pre-set, and then inquiries are made based on the actual load of the CPU currently sampled to determine the current corresponding target link frequency.

[0036] Exemplarily, when query matching is performed to obtain the target link frequency, a query is performed according to the target CPU and the target load, and the link frequency that matches the target CPU and the target load at the same time is used as the target link frequency. Due to the differences in the links corresponding to different combinations of CPUs and loads, when query matching is performed, it includes: according to the target identifier of the target CPU, querying in the frequency modulation mapping table to obtain an intermediate frequency set, wherein the corresponding relationship between the load and the frequency is recorded in the intermediate frequency set; querying in the intermediate frequency set according to the target load to obtain the target link frequency corresponding to the target load.

[0037] That is, when performing query matching, the target CPU and target load can be used as two query conditions, and then queries are performed in sequence according to the conditions. First, the target CPU is used as a condition for query, and then the target load is used as a query condition for query based on the query results to obtain the target link frequency.

[0038] It should be noted that for a terminal, it contains a certain number of CPUs. When performing frequency modulation processing, the entire usage demand is obtained based on the demand of each CPU, and then the CPU link regulator performs frequency modulation processing on the CPU link based on the entire usage demand.

[0039] Step 103: Generate a target frequency modulation strategy according to the target state and the target link frequency, and send the target frequency modulation strategy to the link regulator, so that the link regulator performs frequency modulation processing on the target link corresponding to the target CPU.

[0040] In one embodiment, after the target state and the target link frequency are obtained, a corresponding target frequency modulation strategy is generated, and then the obtained target frequency modulation strategy is sent to the link regulator, so that the link regulator performs frequency modulation processing on the target link corresponding to the target CPU.

[0041] For example, a block diagram of dynamic voltage-frequency adjustment may be as follows: Figure 2 As shown, the CPU scheduling module monitors the CPU in real time, obtains the CPU load and status, and then obtains the CPU link demand based on the CPU load and status, and then informs the CPU link regulator so that the CPU link regulator performs frequency modulation processing on the corresponding CPU link according to the link demand.

[0042] exist Figure 2In the block diagram shown, the CPU scheduling module calculates the CPU load to obtain the CPU load, and also monitors the CPU state in real time to determine whether it is in a dormant state (idle state). The CPU link regulator does not need to calculate the CPU load at this time. By embedding a notification module in the CPU scheduling module, the real-time monitored data is sent to the CPU link regulator to avoid repeated load calculations by the CPU link regulator.

[0043] Further, when performing subsequent processing according to the target state and the target link frequency, reference may be made to Figure 3 , Figure 3 It is a flowchart of the steps of performing frequency modulation processing provided in an embodiment of the present application, wherein the steps include steps 301 to 303.

[0044] Step 301, determining whether the target state is a dormant state;

[0045] Step 302, when it is determined that the target state is not the sleep state, generating a target frequency modulation strategy according to the target link frequency;

[0046] Step 303: Send the target frequency modulation strategy to the link regulator, so that the link regulator performs frequency modulation processing on the target link corresponding to the target CPU.

[0047] Specifically, when performing frequency modulation processing, it is determined whether the obtained target state is a sleep state, and then when it is determined that the target state is not a sleep state, a corresponding target frequency modulation strategy is generated according to the target link frequency, and then the target frequency modulation strategy is sent to the link regulator, so that the link regulator performs frequency modulation processing on the target link corresponding to the target CPU according to the target frequency modulation strategy.

[0048] Exemplarily, when the CPU is in a non-sleep state, it indicates that the link demand required at this time is real. Therefore, a corresponding link adjustment strategy is generated according to the currently obtained target link frequency. Since the frequency modulation processing of the link requires the processing of the link regulator, the link adjustment strategy is sent to the link regulator so that the link regulator performs frequency modulation processing on the CPU link according to the target frequency modulation strategy.

[0049] Furthermore, when the CPU is in a sleep state, a corresponding frequency gear can be set at this time, that is, the sleep state corresponds to a frequency gear, and when performing frequency modulation processing, the obtained target load is not used as a basis for frequency modulation, specifically including: when it is determined that the target state is a sleep state, the default link frequency corresponding to the sleep state is obtained, and a target frequency modulation strategy is generated according to the default link frequency state.

[0050] It should be noted that when the CPU is in a dormant state, it does not mean that the corresponding CPU link is not required to run, but the demand is small. At this time, a corresponding default link frequency can be set for the dormant state. When determining the target frequency modulation strategy, the default link frequency corresponding to the dormant state is obtained to generate the target frequency modulation strategy of the target CPU according to the default link frequency.

[0051] In one embodiment, after the scheduling module completes the acquisition and sampling of the relevant information of the CPU and informs the link regulator, the link regulator will perform the link frequency modulation processing according to the obtained target frequency modulation strategy. After the frequency modulation processing is completed, in addition to acquiring the CPU status and load when the CPU has a task change, the link regulation module can also periodically perform load sampling.

[0052] In actual applications, since the completion of a task does not necessarily run through the entire frequency modulation cycle, within a frequency modulation cycle, there will be a load reduction after the task is completed, that is, the demand for the CPU link is reduced, but the CPU link is still at a high frequency, resulting in a waste of performance process. Therefore, after completing a frequency modulation process and when it is not detected that a new frequency modulation process is needed, the link adjustment module can perform further frequency modulation processing according to the actual situation, and can also share information with the scheduling module. Specifically, after the link regulator completes the frequency modulation processing of the CPU link, it includes: receiving feedback information obtained by the link regulator based on the target frequency modulation strategy, wherein the feedback information is generated by the link regulator based on the sampled load.

[0053] As for the generated feedback information, since it is the sampling and adjustment result of the link regulator, the feedback information at least includes the current load of the target CPU and the current link frequency of the target link.

[0054] It should be noted that after the CPU completes a task, it will be in an idle state, that is, the sleep state (idle state) described above. Under normal circumstances, the scheduling module can monitor the status of the CPU in a timely manner, but there may be special circumstances that cause the scheduling module to fail to monitor it in a timely manner. At this time, the link regulator determines that the load has changed after periodic sampling, but has not received the relevant information sent by the scheduling module, including the target frequency modulation strategy. At this time, the frequency modulation processing can be automatically performed, and corresponding feedback information is generated according to the result of the frequency modulation processing to inform the scheduling module.

[0055] In one embodiment, referring to Figure 4 , Figure 4 It is a block diagram schematic diagram of frequency modulation processing provided in an embodiment of the present application.

[0056] like Figure 4 As shown, when dynamic voltage and frequency adjustment is performed, CPU load tracking is performed to determine the load conditions of each CPU in the terminal or device, so as to obtain the corresponding CPU frequency modulation method according to the obtained load conditions, and at the same time, the idle mode of the CPU is monitored to obtain the idle mode of each CPU, and then the obtained CPU frequency modulation method and idle mode and the sampled load conditions are informed to the CPU link regulator, and finally the CPU link regulator performs CPU link frequency modulation.

[0057] In the actual processing process, combined with Figure 2 When performing load sampling and state mode monitoring, the CPU scheduling module is used to implement it, and then the notification module embedded in the CPU scheduling module sends the acquired relevant data to the CPU link regulator to realize data sharing, avoiding the CPU link regulator from needing to perform load sampling calculations when performing link frequency modulation. At the same time, when sampling the load, the accuracy of frequency modulation is improved through real-time sampling of the load.

[0058] In summary, the present application discloses a dynamic voltage frequency adjustment method. When performing frequency modulation processing, the scheduling module monitors the state of the target CPU to obtain the target state of the target CPU, and also detects and samples the real-time load of the target CPU, and then determines the current corresponding target link frequency according to the sampled target load, and finally obtains the target frequency modulation strategy for frequency modulation processing of the target link according to the target state and the target link frequency, and sends the target frequency modulation strategy to the link regulator, so that the link regulator completes the frequency modulation processing of the target link. In the frequency modulation process, the CPU scheduling module and the CPU link regulator are integrated, and the real-time performance of load sampling is improved through information sharing between the two. At the same time, the CPU state is used as the basis for frequency modulation, so as to improve the accuracy of frequency modulation and reduce power consumption.
