Detailed Description
The invention provides a hardware resource management method, a storage medium and an intelligent terminal, and the invention is further described in detail below in order to make the purposes, technical schemes and effects of the invention clearer and more definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, the present invention provides a method for managing hardware resources, including the steps of:
s100, registering hardware resources in the terminal, and configuring a priority access strategy of each hardware resource;
s200, receiving an access request of an application program to a hardware resource;
s300, searching the priority access strategy corresponding to the hardware resource;
s400, distributing the use right of the hardware resources according to the priority access strategy.
Specifically, in an embedded terminal system, hardware resources are limited, for example, only limited tuner, decoder, memory, camera and the like, and a conventional system often adopts an upper layer control-based method to coordinate the use of the hardware resources, that is, after an application exits, an application can use competing resources.
In order to solve the technical problems, the method for managing the hardware resources adopts the combination of task scheduling and terminal hardware resource access control, and before an application program runs, a system distributes priority to the application program, so that important application has the highest priority in a task queue, and a high-priority application program can preempt the hardware resource occupation time of a low-priority application program. When the high priority application cannot normally run because the required hardware resources are occupied by the low priority application, the high priority application uses the hardware resources preferentially.
In a preferred embodiment, the step S100 specifically includes:
s110, acquiring the hardware resource access authority of each application program; each application may have multiple hardware resource access rights, and prior to configuring the priority policy, it is necessary to obtain all of the hardware resource access rights information that each application has in order to know that each hardware resource is accessible to those applications.
S120, generating an application program list corresponding to each hardware resource according to the hardware resource access rights; after the application programs corresponding to each hardware resource are obtained, the application programs are counted through a list form, so that the application program condition corresponding to each hardware resource is clearly known.
S130, configuring a priority access strategy of each hardware resource based on the application program list. Then, the application programs in the application program list need to be ordered, and the ordering process of the application programs is the process of setting the priority of the application programs for accessing the hardware resources.
In a specific embodiment, the step S130 specifically includes:
s131, acquiring historical operation information of each application program in the application program list; the priority access strategy for configuring the hardware resources is set according to the historical operation information of the application program, the historical operation information of the application program truly reflects the operation rule of the application program, and the priority access strategy is more practical.
S132, acquiring the dependency degree of each application program on hardware resources according to the historical operation information; the historical running information of the application program can indirectly infer the dependency degree of the application program on the hardware resource, for example, the application program calls a certain hardware resource the most in a period of time, and the application program can be seen to have the highest dependency degree on the hardware resource.
S133, configuring a priority access strategy of each hardware resource based on the dependency degree. And setting a priority access strategy according to the dependence degree of the application program on the hardware resource, so that the application program accesses the hardware resource more reasonably and meets the actual application scene requirement.
In a specific embodiment, the historical operating information includes the number of times an application program is run and the number of times each hardware resource is invoked by the application program. Of course, the historical operating information may also include the total operating time of the application program and the time of invoking each hardware resource, including but not limited to the above.
In a specific embodiment, the priority access policy includes:
for the same hardware resource, when the number of times that the application program calls the hardware resource is greater than or equal to a first threshold value, setting the application program as a first priority; for example, the number of times the application program calls the hardware resource is 50 or more in a certain period of time, and it can be considered that the application program frequently calls the hardware resource, and the hardware resource is a necessary hardware resource for realizing the application program function, and the priority of the application program must be set highest for the hardware resource.
Setting the application program as a second priority when the number of times the application program calls the hardware resource is smaller than a first threshold and the running number of the application program is larger than or equal to a second threshold; for example, when the number of times the application program calls the hardware resource is less than 50 times, it may be considered that the application program does not belong to the hardware resource necessary for normal operation of the application program, but in order to further distinguish the importance degree of the hardware resource, the priority of the application program may be further classified according to the number of times the application program is operated (for example, 200 times), and the total number of times the application program is operated exceeds 200 times and is classified as the second priority.
And setting the application program as a third priority when the number of times the application program calls the hardware resource is smaller than the first threshold value and the running number of the application program is smaller than the second threshold value. Obviously, the importance of the first priority application is higher than that of the second priority application, which in turn is higher than that of the second priority application.
In a specific embodiment, the step S400 specifically includes:
s410, acquiring the use state of hardware resources; the use state of the hardware resource specifically includes that the hardware resource is in an occupied state and a non-occupied state.
S420, when the hardware resource is in an occupied state, comparing the priority of the application program currently occupying the hardware resource with the priority of the application program requesting to access the hardware resource; of course, when the hardware resource is in the unoccupied state, no comparison is needed, and if a plurality of application programs simultaneously request the hardware resource, the hardware resource is sequentially accessed from high to low according to the priority of the plurality of application programs.
S430, when the priority of the application program currently occupying the hardware resource is lower than the priority of the application program requesting to access the hardware resource, temporarily releasing the use right of the hardware resource by the application program currently occupying the hardware resource; when the priority of the application program occupying the hardware resource is higher than the priority of the application program requesting to access the hardware resource, returning to the application program requesting to access the hardware resource to apply for the hardware resource, and obtaining the right of use of the hardware resource after the application program waits for the application program occupying the hardware resource to use the hardware resource.
S440, the application program requesting to access the hardware resource obtains the right of use of the hardware resource. The application program requesting to access the hardware resource obtains the hardware resource usage right as the temporary usage right, and the usage right needs to be returned to the last application program occupying the hardware resource after the hardware resource is used up, so that the last application program can normally complete the functional tasks of the application program.
In a more specific embodiment, the hardware resource management method is applied to a resource manager, and after the system is started, the resource manager inquires the hardware resources and the quantity information thereof of the terminal and registers; after the first application program is started, applying for the required hardware resources from the resource manager; the resource manager inquires that the corresponding hardware resource is idle (not occupied), allocates the required hardware resource to the first application program, and changes the state of the hardware resource from idle to occupied. After the second application program is started, applying the same hardware resource to the resource manager;
if the resource manager inquires that the hardware resource is not idle, the first application program and the second application program are both high-priority (first priority); the second application program fails to apply for the hardware resource.
If the resource manager inquires that the hardware resources are not free, the priority of the second application program is not higher than that of the first application program, the second application program cannot acquire the hardware resources, the first application program finishes tasks, the resource management module returns the resources, and the second application program waits for the resource manager to redistribute the hardware resources. And the resource manager receives the returned hardware resource, inquires that the second application program is waiting for the resource, and informs the second application program to use the hardware resource, and the second application program starts the task.
If the resource manager inquires that the hardware resource is not free, the priority of the second application program is higher than that of the first application program. The resource manager forces to solicit hardware resources occupied by the first application. The first application program stops the current task, temporarily returns the resource, waits for the resource manager to issue the hardware resource again, and starts to use the hardware resource to execute the task after the second application program occupies the hardware resource.
In a specific embodiment, the step S440 includes:
s450, returning the right of use of the hardware resource after the application program requesting to access the hardware resource uses the hardware resource. In this embodiment, the hardware resource is a temporary occupation mechanism, so that only the purpose is to ensure that the important application program can use the hardware resource preferentially, and after the application program uses the hardware resource, the application program that occupies the hardware resource continues to use the hardware resource, so that the task of each application program cannot be lost, and the access of the hardware resource is flexible.
In a specific embodiment, the hardware resources include a tuner, a decoder, a memory, and a camera. Of course, the method of the present invention is not only used for hardware resources, but may also be applied to management of software resources in another case.
The present invention provides a storage medium having stored thereon a plurality of instructions adapted to be loaded and executed by a processor to implement the steps of the method of managing hardware resources of any of the above.
In addition, referring to fig. 2, the present invention further provides an intelligent terminal, including: a processor 10, a storage medium 20 communicatively coupled to the processor, the storage medium adapted to store a plurality of instructions; the processor is adapted to invoke instructions in the storage medium to perform steps implementing the method of managing hardware resources as described in any of the above.
