The embodiment of the disclosure provides a resource allocation method 10, which can be applied to terminal equipment such as mobile phones, tablet computers and the like, wherein the terminal equipment comprises a display screen and a processor, the processor is used for processing various tasks of a system, the frequency of the processor determines the processing speed to a certain extent, the time for completing various tasks is shortened, and the high-frequency processing brings high energy consumption while efficiently completing the work. For this reason, the resource allocation method 10 provided in the embodiment of the present disclosure, as shown in fig. 1, includes steps S11 to S12:
Step S11: and determining the value of the sensitive factor based on the current equipment state of the terminal equipment and according to the current user interaction degree, wherein the equipment state comprises a screen-off state and a screen-on state.
According to the requirements of the user on the terminal equipment, the initial judgment can be carried out, in the screen-extinguishing state of the display screen, the condition that the user does not use the terminal equipment can be judged, the user interaction degree in the state is relatively low, and the use requirements of the system on the processing resources in the state are usually from remote network awakening and resource management of a bottom layer system; on the other hand, in the bright screen state of the display screen, the interaction degree of the user is relatively high, whether more resources are needed or not is judged according to the actual task, so that the timely running of the current task and the future task is ensured, and the timeliness and the low delay of the user interaction are ensured. The sensitive factor can be obtained comprehensively according to the state and a plurality of factors, and the value of the sensitive factor is determined according to the state and the task condition of the current terminal equipment.
Step S12, determining and adjusting the frequency of the processor according to the value of the sensitivity factor.
The method comprises the steps that the value of a sensitive factor is obtained according to the state and task condition of current terminal equipment, so that the frequency of a processor which is needed by a system is determined, the processor is further adjusted to the needed frequency, and under the conditions that more resources are needed, such as high user interaction degree, more system tasks and the like, the frequency of the processor is increased, the operation of the system is ensured, and the blocking and delay are reduced; meanwhile, under the current conditions that the user interaction degree is low, the task can be guaranteed to be completed and resources are rich, the frequency of the processor is reduced, and the power consumption is reduced while the task is guaranteed to be completed.
In an embodiment, the sensitivity factor may include a screen-off feedback factor or a screen-on feedback factor, as shown in fig. 2, step S11 may include: step S111, if the terminal equipment is in a screen-off state, determining a value of a screen-off feedback factor according to the currently processed task type; step S112, if the terminal equipment is in the bright screen state, determining the value of the bright screen feedback factor according to the current user process requirement.
In this embodiment, the sensitivity factor may include a screen-in feedback factor and a screen-out feedback factor. When the terminal equipment is in the screen-off state, the system basically has no operation of a user layer, more is the operation requirement of a bottom layer, such as receiving an incoming call, downloading the system and the like, the required resources are generally relatively reduced compared with the screen-on state, so that in the screen-off state, the value of the screen-off feedback factor is determined according to the task category processed by the system, and the frequency of the processor is determined and adjusted. When the terminal equipment is in a bright screen state, a user can operate, the user interaction degree is higher, the user process requirements can be different according to different states of different tasks, and in the bright screen state, the value of a bright screen feedback factor is determined according to the current actual process condition, so that the frequency of a processor is determined and adjusted.
In one embodiment, the off-screen feedback factor may include: using a feedback factor; the resource allocation method 10 may further include: judging the task category of the current processing when the terminal equipment is in the screen-off state; if the currently processed task is a user state task, determining that the value of the feedback factor is a first value of a non-negative number; if the currently processed task is a kernel-mode task, determining that the value of the feedback factor is 0; step 12 may further include: depending on the magnitude of the value of the feedback factor used, the frequency of the processor is correspondingly reduced or maintained.
In this embodiment, in the Linux system, tasks may be classified into a user mode and a kernel mode, where the two tasks have different properties, and in the screen-off state, a value of a feedback factor may be determined according to a task type, that is, whether a current task (task) is a user mode task or a kernel mode task.
If the task is a user-state task, the input of resources can be correspondingly reduced because the user does not use the terminal equipment at present, the first value of the feedback factor is determined to be a non-negative value, and the frequency of the processor is correspondingly reduced according to the first value. In an embodiment, the first value may be a preset fixed value, that is, the specific content of the user mode task is not required to be resolved, and the first value is set to a uniform value, so that the processor uniformly adjusts the frequency when processing the user mode task in the screen-off state. In another embodiment, the first value may be determined according to the interactivity with the user of the user-state task, where the stronger the interactivity, the lower the value of the corresponding off-screen feedback factor. The interactivity of the user mode task can be calculated according to the detection AI of the user layer, the user mode task is generally the task performed by the user before screen-off, the higher the interactivity of the task is, the higher the resources allocated in the screen-on state are, the higher the original frequency of the processor is, therefore, after screen-off, the user stops interacting without the original frequency, the higher the frequency amplitude required to be reduced by the processor is, and the higher the interactivity of the user mode task is, the lower the corresponding value of the screen-off feedback factor is, so that the power consumption is reduced rapidly.
If the current task is a kernel mode task, since the kernel mode task is a system operation requirement, resource investment needs to be ensured, when the current task is the kernel mode task, the value of a used feedback factor is determined to be 0, and the frequency of a processor is maintained based on the value, so that the normal operation of the system is ensured, and the bottom layer function is ensured not to be interfered.
In an embodiment, the off-screen feedback factor may further include: memory clearing a first factor; the resource allocation method 10 further includes: when the terminal equipment is in a screen-off state, if the currently processed task is a memory cleaning task, determining a value of a memory cleaning first factor according to the current memory occupancy rate, wherein the higher the occupancy rate is, the higher the corresponding value of the memory cleaning first factor is; step S12 may further include: and correspondingly increasing or maintaining the frequency of the processor according to the value of the first factor of the memory cleaning.
In this embodiment, in the screen-off state, the system may perform memory cleaning. The memory affects the task operation, when the task is performed, the corresponding memory needs to be called, if the memory is occupied too much when a certain task is started, the requirement of the task needs to be cleaned temporarily, and system delay is caused. Therefore, some systems can clean the memory in the screen-off state. Therefore, the first factor of memory cleaning is set, when the screen is closed, if the current task is to clean the memory, the value of the first factor of memory cleaning can be determined according to the occupancy rate of the memory, and the higher the occupancy rate is, the heavier the cleaning task is, and the higher the processor frequency is needed to ensure timely completion.
The memory cleaning in the screen-off state can be a user-state task, such as user-specified cleaning, or a kernel-state task, such as automatic cleaning by a system, so that the value of the screen-off feedback factor can be comprehensively used with the value of the feedback factor and the value of the first factor of the memory cleaning, and the frequency of the current processor is determined according to the calculation result.
In one embodiment, the bright screen feedback factor may include: load increasing feedback factor or load decreasing feedback factor; the resource allocation method 10 further includes: when the terminal equipment is in a bright screen state, judging the number of times that the process is preempted in non-active switching; if the number of times is greater than the first threshold, determining a value of a load increase feedback factor according to the running condition of the processor; if the number of times is smaller than a second threshold, determining a value of a load reduction feedback factor according to the running condition of the processor, wherein the second threshold is smaller than or equal to the first threshold; step S12 may further include: increasing the frequency of the processor according to the value of the feedback factor of the load increase; or, reducing the frequency of the processor according to the value of the feedback factor of the load reduction.
In this embodiment, in the bright screen state, a load increase feedback factor or a load decrease feedback factor is set, and according to the current task and the current processor frequency, it may be determined that the resource investment is insufficient or excessive, so as to determine the values of the two factors, and then make corresponding adjustment.
Firstly, judging the number of times that processes are preempted and not actively switched in a scheduling clock period of a processor, wherein the processor normally executes the tasks according to the sequence in an operation queue, but some tasks such as keyboard input related to I/O (input/output) and the like need to respond in time, and when the tasks occur, the tasks are inserted into front of the operation queue, so that the processes are preempted, the integration is preempted and not actively switched, if the occurrence number of the conditions is too large in a period of time, some tasks in the operation queue can not be completed in time, and if the occurrence number of the please is small, the tasks represent the current task and are not heavy. By the method, the current system state can be primarily judged.
When the number of times that the process is preempted to be not actively switched is larger than a first threshold value, determining a value of a load increase feedback factor according to the running condition of the processor, and correspondingly increasing the frequency of the processor according to the value of the load increase feedback factor. In one example, the value of the load increase feedback factor may obtain the expected delay length of the operation queue according to the current frequency of the processor and the current operation queue, where the longer the expected delay, the higher the value of the corresponding load increase feedback factor. The method comprises the steps of pre-judging whether the tasks in the queue can be completed on time according to the tasks in the queue and the current processor frequency, and determining the value of a load increase feedback factor according to the expected time delay duration if the tasks in the running queue cannot be completed on time and have time delay conditions. In still other embodiments, the number of new processes is obtained, the greater the number of new processes, the higher the corresponding load increase feedback factor value. In addition to running queues, the system may also increase processes in some cases, if the number of new processes is large, it may cause the system to get stuck, and according to the number of new processes, the load is increased to increase the value of the feedback factor, so as to further increase the frequency of the processor.
When the number of times that the process is preempted and not actively switched is smaller than a second threshold, the possible resource investment of the current system is represented to be excessive, the value of the load reduction feedback factor is determined according to the running condition of the processor, and the frequency of the processor is correspondingly reduced according to the value of the load reduction feedback factor. In one example, according to the current frequency of the processor and the current running queue, the predicted advance time of the running queue is obtained, the longer the predicted advance time is, the lower the corresponding load reduction feedback factor is, the value of the load reduction feedback factor is a negative number, the longer the predicted advance time is, the higher the resource investment is, the larger the amplitude of the processor frequency needs to be reduced, so that the lower the corresponding load reduction feedback factor is, the more processor frequency is reduced, and the power consumption is reduced.
In an embodiment, the bright screen feedback factor may further include: displaying the demand load factor; the resource allocation method 10 further includes: when the terminal equipment is in a bright screen state, determining a value of a display demand load factor according to the resource demand of the current task on the screen display, wherein the higher the resource demand of the current task on the screen display is, the higher the value of the display demand load factor is; step S12 may further include: the frequency of the processor is increased accordingly, based on the value of the display demand load factor.
In this embodiment, in the bright screen state, the current required resource can be predicted by AI or other modes according to the real content and the type of the current task displayed. Some tasks, such as electronic games, require real-time switching of pictures and timely response, thus requiring more resources, while some tasks do not require excessive resources for display. Therefore, a display demand load factor is also set in the bright screen feedback factor, the value of the display demand load factor is determined according to the resource demand of the current task on the screen display, and the frequency of the processor is correspondingly increased according to the value of the display demand load factor.
In an embodiment, the bright screen feedback factor may further include: memory clearing a second factor; the resource allocation method 10 may further include: when the terminal equipment is in a bright screen state, if the current memory needs to be cleaned, determining a value of a memory cleaning second factor according to the occupancy rate of the current memory, wherein the higher the occupancy rate is, the higher the value of the corresponding memory cleaning second factor is; step S12 may further include: and correspondingly increasing the frequency of the processor according to the value of the second factor of the memory cleaning.
In this embodiment, in the state of screen brightness, the system determines according to the actual conditions of the task and the memory, and needs to clean the memory in time to ensure the normal call of the task, so that when the memory needs to be cleaned, the corresponding allocation resource is needed. And determining the value of the second memory cleaning factor according to the occupancy rate of the memory, wherein the higher the occupancy rate of the memory is, the more memories need to be cleaned, and the higher the value of the corresponding second memory cleaning factor is, so that the frequency of the processor is correspondingly increased to a higher frequency.
The resource allocation method 10 provided by the embodiment of the disclosure can set corresponding factors according to the system state by combining various factors, memorize the frequency of the processor determined and adjusted according to the values of the factors, avoid blocking and delay, reduce power consumption and ensure the interactive experience of users.
According to the embodiment of the disclosure, through experiments, the power consumption of the mobile phone is tested as follows:
