In this embodiment of the present invention, referring to FIG. 1 , the electronic device includes a first processor 1 and a power consumption monitoring module 2 , and the power consumption monitoring module 2 is connected to the first processor 1 to monitor the power consumption of the first processor 1 analysis.

Specifically, in this embodiment, the power consumption monitoring module 2 includes: a second processor 2001, a memory 2002, a timer 2003, and the like. The memory 2002 may be high-speed RAM memory, or may be non-volatile memory, such as disk memory.

In the device shown in FIG. 1 , the processor 1001 can be used to call the computer program stored in the memory 1002 and execute the relevant steps of the method for obtaining the power consumption of the processor in the following embodiments.

An embodiment of the present invention further provides a method for obtaining power consumption of a processor, which is applied to analyze the power consumption of the first processor.

Referring to FIG. 2 , an embodiment of a method for obtaining power consumption of a processor of the present application is proposed. In this embodiment, the method for obtaining the power consumption of the processor includes:

Step S10, obtaining a target time period and a target operating frequency; the target time period is the time period during which the processor invokes the target thread to perform a task, and the target operating frequency is the operating frequency of the processor within the target time period;

The target thread specifically refers to a thread called by the processor to execute a task in the running scenario when analyzing the processor energy consumption of the electronic device in a specific scenario. The target thread can be determined based on the test instruction, or all threads in a specific running scenario can be used as the target thread. The target thread's data can have one or more than one as needed.

The specific scene here can be set according to the actual situation. It can be the scene when the operating parameters of the electronic device reach the set state during the operation of the electronic device, or the entire running process of the electronic device from power-on to the current moment or to the power-off time, or The operating state of the electronic equipment when the set detection command is received, etc.

For a target thread, its corresponding target time period may have one or more than one according to the actual situation. Specifically, in a specific scenario, when the processor calls the target thread once, there is one target time period, and when the processor calls the target thread more than once, there is more than one target time period.

During its operation, the processor may have different operating frequencies in different time periods. The target operating frequency is specifically the actual frequency at which the processor operates within the target time period. If the processor operates at a fixed frequency within the target time period, the number of target operating frequencies is one; if the processor operates at different frequencies within the target time period, the number of target operating frequencies is more than one.

The target time period and target operating frequency can be obtained by obtaining the parameters input by the tester; it can also be extracted from the operating information recorded during the operation of the electronic device after it is turned on; it can also be generated by reading the electronic device in the processor power consumption monitoring mode. Monitoring log data analysis is obtained.

Step S20, determining a power consumption parameter of the processor according to the target time period and the target operating frequency.

The power consumption parameter is specifically a characteristic parameter representing the size of the processor's consumption resources, which may be a specific value or a power consumption level.

The power consumption parameters of the processor include the power consumption parameters when the processor executes a single thread, the processor executes multiple threads (which can be some or all threads in a process, or multiple threads that perform critical tasks in different processes) power consumption parameters when the processor executes a single process (a process may include a single thread or multiple threads), power consumption parameters when the processor executes multiple processes and/or the operating system ( Such as Android system) power consumption parameters, etc.

The corresponding relationship between the target time period, the target operating frequency and the power consumption parameter can be preset, which can be a calculation formula, a mapping relationship, a machine learning model, and the like. Based on the corresponding relationship, the power consumption parameters of the processor corresponding to the current target time period and the target operating frequency can be determined.

In this embodiment, the power consumption parameter of the processor may be calculated according to the duration corresponding to the target time period and the target operating frequency. Specifically, the target time period corresponding to the target thread is from T to T', and when the operating frequency of the processor in this time period is fixed as F, then (T'-T)*F can be used as the power consumption parameter of the processor.

Further, in another embodiment, the target operating frequency includes at least two different sub-frequency, and the step of determining the power consumption parameter of the processor according to the target time period and the target operating frequency includes: : determine the sub-time period corresponding to each of the sub-frequency in the target time period; determine the power consumption parameter according to each of the sub-time period and its corresponding sub-frequency. For example, the target time period corresponding to the target thread is T to T', the processor runs at the F1 frequency in the T to T" time period during the target time period, and the processor runs at the F2 frequency in the T" to T' time period. Then the power consumption parameter of the processor=(T"-T)*F1+(T'-T")*F2.

An embodiment of the present invention provides a method for obtaining power consumption of a processor, which determines a power consumption parameter of a processor in combination with a target time period during which the processor calls a target thread to execute a task and the operating frequency of the processor in the target time period. The target time period and target operating frequency are the relevant operating parameters when the processor calls the target thread to execute the task, so the obtained power consumption parameter can accurately reflect the energy consumption during the process of the processor calling the thread to execute the task, and is not subject to other power consumption. The influence of the power consumption of the device can effectively improve the accuracy of the power consumption acquisition result of the processor, ensure that the power consumption acquisition result of the processor can provide an accurate basis for the optimization of the battery life performance of the device, and effectively improve the battery life of the electronic device.

Further, based on the above embodiment, another embodiment of the method for obtaining power consumption of a processor of the present application is proposed. In this embodiment, there are multiple target threads, and there are also multiple target time periods and target operating frequencies obtained correspondingly; wherein, there may be one or more target time periods corresponding to each target thread (according to The number of times the processor calls each target thread is specifically determined), and each target time period corresponds to one or more target operating frequencies (specifically determined according to the actual operation of the processor in the time period). Based on this, referring to FIG. 3 , the step S20 includes:

Step S21, determining the sub-power consumption parameter when the processor calls each of the target threads according to the target time period and target operating frequency corresponding to each of the target threads;

A target thread corresponds to a sub-power consumption parameter. The sub-power consumption parameter corresponding to each target thread can be obtained by calculating, mapping or substituting into the algorithm model the target time period and target operating frequency corresponding to each target thread according to the preset corresponding relationship.

Referring to FIG. 4 , FIG. 4 shows relevant operating parameters when the processor executes a task for a period of time when the electronic device is powered on. Specifically, Figure 4a represents the time information when different processors call different threads to execute tasks, wherein A, B, and C represent different threads, and the bulge relative to the baseline represents the corresponding thread call; Figure 4b represents the processing The operating state information (operating state or non-operating state) of the processor, the protrusion relative to the baseline indicates that the processor is in the operating state; Figure 4c represents the operating frequency of the processor at different times, and the height of the protrusion represents the frequency size. Wherein, in this embodiment, T0 specifically refers to the start time of the processor after the electronic device is powered on. In other embodiments, T0 may also be the time when the electronic device reaches a set condition in a running state (eg, the power level is lower than a set threshold or a set instruction is received, etc.).

Based on this, the sub-power consumption parameter M1 of thread A=F0*(T1-T0)+F1*(T5-T4); the sub-power consumption parameter M2 of thread B=F0*(T3-T2)+F1*(T6- T5); the sub-power consumption parameter of thread C M3=F1*(T7-T6); in addition, the processor does not call the thread to perform tasks during the T1-T2 time period, based on this, it can also be determined that the processor is equipped with The power consumption parameter of the operating system M4=F0*(T2-T1).

Step S22, determining all sub-threads corresponding to the target process in the multiple described target threads;

The target process is specifically the process executed by the processor that needs to obtain power consumption. The target process can be determined according to the received test instructions (which can be issued by the tester), or can be determined by the processor when the electronic equipment runs to a set state (for example, the power is lower than the set threshold or the power consumption rate is greater than the set rate, etc.). Execute in and out as the target process.

Among them, during the operation of the electronic device, when the processor executes a certain task process, the processor can call multiple threads to execute multiple sub-tasks corresponding to the task in parallel, and the system will record the process ID of the executed process and the thread ID of the corresponding thread. The corresponding relationship between processes and threads is formed. Based on this, by acquiring the correspondence between processes and threads, all child threads corresponding to the target process can be determined.

Step S23, determining a total power consumption parameter when the processor executes the target process according to the sub-power consumption parameters of all sub-threads corresponding to the target process;

Specifically, the sum of all sub-power parameters may be used as the total power consumption parameter.

For example, if all threads corresponding to the target process are the above-mentioned thread A and thread B, the total power consumption parameter corresponding to the target process=M1+M2.

Step S24, determining that the total power consumption parameter is the power consumption parameter of the processor.

It should be noted that, in other embodiments, M1+M2+M3 may also be used as the power consumption parameter of the processor; or, M1+M2+M3+M4 may be used as the power consumption parameter of the processor, and so on.

In this embodiment, a process is the smallest unit that runs independently and owns resources in the process of a computer performing a task. Therefore, a process can reflect the resource allocation of the processor when performing a specific task. Here, the above steps can be used to obtain processing in units of processes. The power consumption parameters during the execution of tasks by the processor can ensure that the obtained power consumption parameters can accurately reflect the power consumption of the processor when the allocated resources are fixed, so as to achieve accurate representation of the power consumption of the processor.

Further, based on any of the above embodiments, another embodiment of the method for obtaining power consumption of a processor of the present application is proposed. In this embodiment, referring to FIG. 5 , the step S10 includes:

Step S11, acquiring the thread scheduling log, the processor status log and the processor frequency log corresponding to the processor;

The thread scheduling log is specifically log information recorded in the process of the processor invoking the thread to execute the task. The processor status log is specifically log information that records whether the processor is running after the electronic device is powered on. The processor frequency log is specifically log information that records the running frequency of the processor during the running process.

The thread scheduling log, the processor status log, and the processor frequency log may be generated specifically when the electronic device is in set mode. The setting mode is specifically a mode for monitoring the power consumption of the processor of the electronic device. Specifically, the electronic device can enter the setting mode when the operation of the electronic device reaches the set condition (for example, when the power of the electronic device is lower than the set power), or control the electronic device to enter the setting mode when receiving the setting instruction input by the tester or the user. Set mode.

Specifically, before step S11, when the electronic device is in the setting mode, the processor state log is generated according to the state information of the processor and the current time stamp; the state information is information about whether the processor is in a running state ; Generate the thread scheduling log according to the identification information of the thread scheduled by the processor (such as the following thread id, thread name, etc.), the task status information of the thread (such as the following sched_start, sched_end, etc.) and the current timestamp; The processor frequency log is generated according to the running frequency value of the processor and the current time stamp; wherein the setting mode is a mode for monitoring the power consumption of the processor of the electronic device, and the time stamp is obtained from all Start timing when the electronic device is turned on. Here, when the power consumption of the processor needs to be monitored, the corresponding data is obtained to generate the log data required for monitoring the power consumption of the processor, so that the status data related to the tasks executed by the processor can be quickly obtained when the power consumption of the processor is obtained subsequently. , which is beneficial to improve the rate of processor power consumption acquisition, and realize the fast and accurate realization of processor power consumption acquisition.

Specifically, after obtaining the corresponding information, the above three types of logs can be generated according to the preset log format. In this embodiment, the three types of log formats and their log contents are as follows:

1. Thread scheduling log:

Log format: [thread name]-[thread number][space](process number)[space][timestamp][:][thread task][:][CPU index];

Parameter Description:

[Thread name] The thread name to which the currently running task belongs;

[Thread number] The thread id to which the currently running task belongs;

[process number] the process id to which the current running task belongs; wherein, when all processes corresponding to the target process are determined in the above-mentioned embodiment, the process number and thread identifier (thread number or thread name) recorded in the thread scheduling log here can be analyzed and obtained Correspondence between threads and processes.

[Timestamp] The running time from boot to current, in milliseconds, or accurate to nanoseconds;

[Thread task] has two values, sched_start represents the start of the task, and sched_end represents the end of the task scheduling;

[CPU index] The unique identifier of the CPU, which indicates which CPU is currently scheduled to execute. The CPU index is specifically used to distinguish the log data of different processors. The thread scheduling log corresponding to the target processor can be determined by the CPU index here.

Example: Binder:571_1-649(571)92103.062452:sched_start:cpu_id=2.

Wherein, log data can be generated by obtaining corresponding information according to the agreed log format here at intervals of a set time period after the electronic device is turned on. During the operation of the electronic device, in the setting mode, the electronic device port can use different processors to call threads to execute tasks. When each processor executes a task, it can generate corresponding log data according to the log format here, and save the log data. To the memory to form a thread scheduling log.

2. Processor status log:

Log format: [thread name]-[thread number][space](process number)[space][timestamp][:][CPU status][:][status information][CPU index];

Parameter Description:

[Thread name] is fixed to idle;

[Thread number] is fixed to 0;

[Process ID] is fixed to -----;

[Timestamp] The running time from boot to current, in milliseconds, and accurate to nanoseconds;

[CPU status] A fixed value of cpu_idle, which means the current data is the processor status log;

[Status information] represents whether the current CPU is in the running state, 0 means running, other means not running, the keyword is state=;

[CPU index] The unique identifier of the CPU, which indicates which CPU is currently scheduled to be executed, and the keyword is "cpu_id=". The CPU index is specifically used to distinguish the log data of different processors. The processor status log corresponding to the target processor can be determined by the CPU index here.

Example: <idle>-0(-----)92103.062452:cpu_idle:state=2cpu_id=2.

Wherein, log data can be generated by obtaining corresponding information according to the agreed log format here at intervals of a set time period after the electronic device is turned on. After the electronic device is turned on, different processors in the electronic device can run or stop running according to the task execution requirements in the setting mode, and each processor can generate corresponding logs in the log format here in the running state or in the non-running state. The log data is stored in the memory to form the processor status log.

3. Processor frequency log:

Log format: [thread name]-[thread number][space](process number)[space][timestamp][:][CPU frequency][:][frequency information][CPU index];

Parameter Description:

[Thread name] is fixed to run;

[Thread number] is fixed to 0;

[Process ID] is fixed to -----;

[Timestamp] The running time from boot to current, in milliseconds, and accurate to nanoseconds;

[CPU frequency] A fixed value of cpu_frequency, which means the current data is the processor frequency log;

[Frequency information] represents the current CPU operating frequency value, the keyword is state=;

[CPU index] The unique identifier of the CPU, which indicates which CPU is currently scheduled to be executed, and the keyword is "cpu_id=". The CPU index is specifically used to distinguish the log data of different processors. The processor frequency log corresponding to the target processor can be determined by the CPU index here.

Example: <run>-0(-----)92103.062452:cpu_frequency:state=2016000cpu_id=2.

Wherein, log data can be generated by obtaining corresponding information according to the agreed log format here at intervals of a set time period after the electronic device is turned on. After the electronic device is turned on, different processors in the electronic device can run or stop running according to the task execution requirements in the setting mode. When each processor runs at a fixed or different frequency in the running state, it can generate corresponding logs according to the log format here. The log data is stored in the memory to form the processor frequency log.

Further, before obtaining the above three kinds of logs to obtain the processor power consumption, the thread scheduling log, the processor status log and the processor frequency log may be saved in the form of a circular linked list. Since the above three kinds of logs are continuously generated in the setting mode after the device is powered on, the log data is saved in the form of a circular linked list, which is beneficial to reduce the memory space occupied by the log storage and facilitate the subsequent processor power consumption to obtain efficiency and accuracy.

Step S12, determining the running time period of the processor according to the processor state log;

The running time period refers to the time period when the processor is in the running state. The running time period of the processor can be obtained by parsing the data in the processor status log.

Specifically, when the processor status log contains a set status identifier, the running time period is determined according to a first timestamp of the processor status log; wherein the first timestamp is where the processor is located The running duration of the electronic device from power-on to when the processor state log is generated, and the set state identifier is an identifier when the processor is in a running state. In this embodiment, the processor state log may include a plurality of state data saved in the above log format, and when the "state information" field in the plurality of state data is state=0, the timestamp of the piece of state data can be extracted, The time period corresponding to the extracted time stamp set can be used as the running time period of the processor.

Specifically, the sequence diagram shown in Figure 4b is generated according to the analysis result of the processor state log. Based on Figure 4b, it can be determined that the processor is in the running state during the time period from T0 to T7, that is, the running time of the processor The segment is the time period from T0 to T7.

Step S13, determining the target time period corresponding to the target thread within the running time period according to the thread scheduling log;

The thread scheduling log includes several pieces of scheduling data, the data corresponding to the running time period is screened in the several pieces of scheduling data, and the target time period is obtained by parsing the log content of the screened scheduling data.

Specifically, the scheduling data includes the identification information of the thread scheduled by the processor, the task status information of the thread, and a corresponding second time stamp, and the second time stamp is the time from the boot to the time when the device where the processor is located. The running duration when the scheduling data is generated determines the target scheduling data in the thread scheduling log; the target scheduling data is that the second timestamp is within the running time period, and the identification information is the target thread The scheduling data of the identifier; the second time stamp of the first target data is determined as the first target time, and the second time stamp of the second target data is determined as the second target time; the first target data is the target The task status information in the scheduling data is the scheduling data of the task start (such as the above-mentioned sched_start), and the second target data is the scheduling data of the task status information in the target scheduling data that the task ends (such as the above-mentioned sched_end); The first target time and the second target time determine the target time period. Specifically, if there is one first target time and one second target time, the time period between the first target time and the second target time may be the target time period; if the first target time and the second target time are longer than If there is more than one target time period, the time period between the adjacent first target time and the second target time is respectively used as the target time period, then the obtained target time period is more than one. The target time is the start of time.

Specifically, the thread scheduling log can specifically include a plurality of scheduling data stored in the above log format. Based on this, firstly, all scheduling data can be filtered based on the matching result between the timestamp in the scheduling data and the target time period, and the timestamp is in Within the target time period, it is used as the target scheduling data, and if the timestamp is not within the target time period, it will not be processed temporarily.

The power consumption rate here is a parameter that characterizes the power consumption speed of the battery of the electronic device.

After the electronic device is turned on, the power consumption of the electronic device in a unit time is detected by the interval setting of the power monitoring module, and the ratio of the power consumption to the unit time is used as the power consumption rate here. The unit time here can be specifically set according to the analysis requirements.

Specifically, in the above setting mode, the above three types of logs are generated and the step S01 is executed at the same time, and the above generated three types of logs can be stored in the memory in the form of a circular linked list.

Step S02, judging whether the power consumption rate is greater than or equal to a set rate threshold;

When the power consumption rate is greater than or equal to a set rate threshold, the step of acquiring a target time period and a target operating frequency is performed.

The specific size of the set rate threshold can be set according to the actual situation. If the power consumption rate is greater than or equal to the set rate threshold, it indicates that the power consumption of the electronic device is too fast. At this time, the power monitoring module generates a save signal. When the generation of the save signal is detected, the log data in the memory is saved to the non-volatile memory (flash). memory), based on this, the target time period and target operating frequency can be obtained by reading log data in the non-volatile memory and analysing the log data in the non-volatile memory in subsequent real-time or delayed or when receiving the set power consumption acquisition instruction.

In this embodiment, when the power consumption of the electronic device is too fast, the acquisition of the power consumption of the processor is triggered, which is beneficial to determine the cause of the excessive power consumption of the electronic device based on the power consumption acquisition result, so as to provide more effective optimization of the battery life performance of the electronic device A more accurate basis to achieve the improvement of the battery life of electronic equipment.

It should be noted that, in other embodiments, when the log data parsing method is not used to obtain the target time period and the target operating frequency, there is no need to generate a log in the process of monitoring the power consumption rate. When the power consumption rate is greater than or equal to When setting the rate threshold, obtain the target time period and target operating frequency according to other methods (such as manual input, etc.).
