The operating system related to the embodiment of the invention is a software system which performs unified management on hardware resources and provides a service interface for a user.
Fig. 1B is a schematic diagram of a program running space of a smart phone according to an embodiment of the present application, where a mobile terminal such as a smart phone is generally provided with a program running space, and the program running space includes a user space and an operating system space, where the user space runs one or more application programs, the one or more application programs are third-party application programs installed on the mobile terminal, and the operating system space runs an operating system of the mobile terminal. The mobile terminal can specifically run an Android system, a mobile operating system iOS developed by apple Inc., and the like, and the mobile terminal is not limited herein. As shown in fig. 1C, for example that the mobile terminal runs the Android system, the corresponding user space includes Application layers (Applications) in the Android system, and the operating system space may include an Application Framework layer (Application Framework) in the Android system, a system Runtime library layer (including system Runtime Libraries and Android Runtime runtimes), and a Linux Kernel layer (Linux Kernel). The application layer comprises various application programs which are directly interacted with the user or service programs which are written by Java language and run in the background. For example, programs that implement common basic functions on smartphones, such as Short Messaging Service (SMS) SMS, phone dialing, picture viewer, calendar, games, maps, World Wide Web (Web) browser, and other applications developed by developers. The application framework layer provides a series of class libraries required by Android application development, can be used for reusing components, and can also realize personalized extension through inheritance.

It can be seen that the third party application program wants to call the function provided by the operating system, and can only call the standard interface function provided by the third party application program. Meanwhile, the operating system does not know which functions the third-party application specifically executes, and the target application cannot command the operating system to execute special operations, which are independent from each other, so that the operating system cannot distinguish the internal operating scene of the target application, can only use one set of standard parameters for adaptation, and cannot perform targeted performance optimization for the internal operating scene of the target application.
In view of the above situation, an embodiment of the present application provides a resource configuration method for a target application of a mobile terminal, in which an operating system of the mobile terminal first detects that an API of the target application applies for camera hardware, obtains a reference duration corresponding to at least one operation in a camera preview process, determines an adjustment amount of system resources in the camera preview process according to an actual processing duration of the at least one operation and the corresponding reference duration, and finally adjusts configuration of the system resources according to the adjustment amount. Therefore, the operating system can adjust the configuration of the system resources more finely through time length comparison in a refined operation level included in the camera preview process, the refinement degree of the system resource configuration performed by the mobile terminal is improved, and the adjustment amount can be used for applying for more system resources and releasing the system resources, so that balance control between performance and power consumption is realized.
Embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flowchart illustrating a resource allocation method according to an embodiment of the present application, where an operating system and one or more application programs run on the mobile terminal, as shown in the figure, the resource allocation method includes:
s201, the operating system detects that a target Application Programming Interface (API) applies for camera hardware, and obtains reference time length corresponding to at least one operation in the camera previewing process.
The target application program refers to a third-party application program installed in a user space of the mobile terminal, the third-party application program may be, for example, a camera application program, an instant messaging application, a game application, or the like, and the third-party application program may be installed by a user or may be pre-installed by a developer before the mobile terminal leaves a factory, which is not limited herein. The camera hardware comprises a front camera or a rear camera and other peripherals. The camera preview process refers to a process that the mobile terminal collects image information in a shooting range through camera hardware and displays the image information on a camera preview interface, the process is involved in various scenes such as shooting, chatting and video, and specific scenes related to the camera hardware are not limited.
Wherein the at least one operation comprises at least one of: interface content acquisition operation, interface rendering operation and interface display operation.
S202, the operating system determines the adjustment amount of the system resources in the camera previewing process according to the actual processing time length of the at least one operation and the corresponding reference time length.
The reference processing duration refers to the longest processing duration that guarantees the lowest frame rate of the camera preview interface, that is, the longest processing duration that guarantees the camera preview interface not to be stuck at the lowest, and the processing duration may be an empirical value, and is also preset by a manufacturer or a user, and is not limited uniquely here.
Wherein the system resources include at least one of: CPU resources, GPU resources, memory bandwidth resources and disk resources.
S203, the operating system adjusts the configuration of the system resource according to the adjustment amount.
It can be seen that, in the embodiment of the present application, an operating system of a mobile terminal first detects that a target application programming interface API applies for camera hardware, obtains a reference duration corresponding to at least one operation in a camera preview process, then determines an adjustment amount of system resources in the camera preview process according to an actual processing duration of the at least one operation and the corresponding reference duration, and finally adjusts configuration of the system resources according to the adjustment amount. Therefore, the operating system can adjust the configuration of the system resources more finely through time length comparison in a refined operation level included in the camera preview process, the refinement degree of the system resource configuration performed by the mobile terminal is improved, and the adjustment amount can be used for applying for more system resources and releasing the system resources, so that balance control between performance and power consumption is realized.
In one possible example, the determining, by the operating system, an adjustment amount of a system resource of the camera preview process according to the actual processing duration of the at least one operation and the corresponding reference duration includes: when the operating system detects that the actual processing time length of the at least one operation is greater than the corresponding reference time length and a first difference between the actual processing time length of the at least one operation and the corresponding reference time length is greater than a first preset difference, determining an adjustment amount of the system resource in the camera previewing process;
the operating system adjusts the configuration of the system resource according to the adjustment amount, and the method comprises the following steps: and the operating system additionally applies for system resources corresponding to the adjustment quantity to run the camera preview process.
The first preset difference may be obtained by multiplying the reference processing time length by a preset coefficient, and if the reference processing time length is 30ms and the coefficient is 0.2, the first preset difference is 6 ms. The first preset difference value can ensure that the operating system stably runs the camera preview process when the first difference value is small, and can timely adjust resources for adaptation when the first difference value is large, so that the stability of resource configuration is improved.
In a specific implementation, before applying for an additional system resource, the mobile terminal may first detect a resource amount of a remaining system resource of the current system, if the resource amount of the remaining system resource is greater than the adjustment amount, the operating system may directly configure, and if the resource amount of the remaining system resource is less than the adjustment amount, the operating system needs to release more system resources, specifically, may clear a background application program to release the system resource.
As can be seen, in this example, for the situation that the actual processing time is long, the mobile terminal can determine the adjustment amount at an appropriate time in time, and additionally apply for the system resource corresponding to the adjustment amount to run the camera preview process, so that the camera preview process is not jammed, and the stability of resource configuration is improved.
In this possible example, the operating system determining an amount of up-adjustment of a system resource of the camera preview process includes: and the operating system determines the up-regulation adjustment quantity of the system resource of the camera preview process according to the first difference value.
The influence degree of the system resource on the operation performance can be obtained through testing or historical record analysis, so that the operating system can obtain the corresponding relationship between the resource amount of the system resource and the performance influence factor, the performance influence factor can include the processing time length, and the operating system can further query the mapping relationship to determine the resource amount of the system resource corresponding to the first difference, namely the corresponding upward adjustment amount of the system resource in the camera preview process.
As can be seen, in this example, the operating system can accurately determine the amount of adjustment of the system resource in the camera preview process by using the first difference, and the accuracy is high and the error is small.
In this possible example, after the operating system adjusts the configuration of the system resource according to the adjustment amount, the method further includes: the operating system acquires a frame loss record of the camera preview process; and the operating system adjusts the first preset difference value downwards according to the frame loss record.
The operating system may record a frame loss record of the camera preview process, where the frame loss record may specifically include information such as the frame number or frequency of frame loss. In a specific implementation, the operating system may determine the adjustment amount of the first preset difference according to the number of frame loss, and perform down-regulation.
It can be seen that in this example, after the operating system adjusts the system resources, the camera preview process still has frame loss, and by adjusting the first preset difference value downward, the operating system can perform optimal configuration on the process earlier, so that the frame loss probability is reduced as much as possible, and the resource configuration efficiency and accuracy are improved.
In one possible example, the determining, by the operating system, an adjustment amount of a system resource of the camera preview process according to the actual processing duration of the at least one operation and the corresponding reference duration includes: when the operating system detects that the actual processing time length of the at least one operation is smaller than the corresponding reference time length and a second difference value between the actual processing time length of the at least one operation and the corresponding reference time length is larger than a second preset difference value, determining a downward adjustment amount of system resources in the camera previewing process;
the operating system adjusts the configuration of the system resource according to the adjustment amount, and the method comprises the following steps: and the operating system releases the system resource corresponding to the down-regulation adjustment amount from the system resource configured in the camera preview process.
The second preset difference may be obtained by multiplying the reference processing time length by a preset coefficient, and if the reference processing time length is 20ms and the coefficient is 0.5, the second preset difference is 10 ms. The second preset difference value can ensure that the operating system stably runs the camera preview process when the second difference value is smaller, and can release idle system resources in time to reduce power consumption when the second difference value is larger.
It can be seen that, in this example, the operating system releases the system resources by the second difference value, and power consumption is reduced in time.
In this possible example, the operating system determining a downshifting adjustment amount of a system resource of the camera preview process includes: and the operating system determines the downward adjustment amount of the system resource of the camera previewing process according to the difference value.
The influence degree of the system resource on the operation performance can be obtained through testing or historical record analysis, so that the operating system can obtain the corresponding relationship between the resource amount of the system resource and the performance influence factor, wherein the performance influence factor can include the processing duration, and further the operating system can query the mapping relationship to determine the resource amount of the system resource corresponding to the second difference, namely the corresponding down-regulation adjustment amount of the system resource in the camera preview process.
As can be seen, in this example, the operating system may specifically determine the down-regulation adjustment amount of the system resource in the camera preview process accurately through the second difference, and release the idle system resource in time to reduce power consumption, so as to better balance the performance requirement and the actual power consumption.
In this possible example, after the operating system adjusts the configuration of the system resource according to the adjustment amount, the method further includes: the operating system acquires a frame rate record of the camera preview process; and the operating system adjusts the second preset threshold value downwards according to the frame rate record.
The operating system may record a frame rate record of the camera preview process, and the frame rate information may be used to determine whether to drop a frame in combination with a lowest frame rate of the camera preview process. In a specific implementation, the operating system may determine that no frame loss occurs in the camera preview process according to the frame rate record and the lowest frame rate in the camera preview process, and then adjust the second preset threshold downward.
As can be seen, in this example, after the operating system adjusts the system resources, no frame loss occurs in the camera preview process, and by adjusting the second preset difference value downward, the operating system can release idle system resources earlier, thereby reducing power consumption as much as possible.
Referring to fig. 3, fig. 3 is a schematic flowchart of a resource allocation method according to an embodiment of the present application, and the method is applied to a mobile terminal, where the mobile terminal runs an operating system and one or more application programs. As shown in the figure, the resource allocation method includes:
s301, the operating system detects that a target Application Programming Interface (API) applies for camera hardware, and obtains a reference time length corresponding to at least one operation in the camera preview process.
S302, when the operating system detects that the actual processing time length of the at least one operation is greater than the corresponding reference time length and that a first difference between the actual processing time length of the at least one operation and the corresponding reference time length is greater than a first preset difference, determining an adjustment amount of the system resource in the camera previewing process.

S305, the operating system acquires the frame loss record of the camera preview process.
S306, the operating system adjusts the first preset difference value downwards according to the frame loss record.
It can be seen that, in the embodiment of the present application, an operating system of a mobile terminal first detects that a target application programming interface API applies for camera hardware, obtains a reference duration corresponding to at least one operation in a camera preview process, then determines an adjustment amount of system resources in the camera preview process according to an actual processing duration of the at least one operation and the corresponding reference duration, and finally adjusts configuration of the system resources according to the adjustment amount.

In addition, aiming at the situation that the actual processing time is long, the mobile terminal can timely determine the up-regulation adjustment amount at a proper time, and additionally applies for system resources corresponding to the up-regulation adjustment amount to operate the camera preview process, so that the camera preview process is not blocked, and the stability of resource configuration is improved.
In addition, the operating system can accurately determine the up-regulation adjustment quantity of the system resources in the camera preview process through the first difference, and the accuracy is high and the error is small.
