Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
At present, when more applications run in the background of the terminal, the applications run in the background occupy a large amount of memory resources. In order to avoid the situation that the foreground running application cannot run normally or runs in a stuck state due to insufficient memory, the terminal operating system introduces a memory recovery mechanism. However, the existing recovery mechanism is based on the condition that the terminal is not available and the idle memory is not enough to run foreground application, and then triggered memory recovery is performed, so that the situation that the application running in the foreground is blocked or the speed of executing operation is slowed down due to the fact that the required memory cannot be applied in time is easily caused.
The embodiment of the disclosure provides a memory recovery method. In the memory recovery method, when the preset application is started, a memory prediction value which needs to be consumed when the preset application executes the designated operation is obtained, if the memory prediction value which needs to be consumed when the preset application executes the designated operation is determined, when the preset application executes the designated operation, the memory recovery condition is met, the terminal is triggered to recover the memory occupied by other applications different from the first application, the timeliness of memory recovery is ensured, and the situation that when the preset application executes the designated operation, the memory recovery triggered due to insufficient free memory available for the terminal causes the preset application to be blocked when executing the designated operation or the speed is slowed down when executing the designated operation is avoided.
Fig. 1 is a flowchart illustrating a memory reclamation method according to an exemplary embodiment, where as shown in fig. 1, the memory reclamation method is used in a terminal and includes the following steps.
In step S11, in response to the first application starting, a predicted value of the memory that needs to be consumed when the first application performs the specified operation is determined.
In this disclosure, the first application may be a preset application installed in the terminal. The designating operation may be preset, and the first application may be executed by an operation that consumes more memory.
For example, the first application may be a camera application, the designation operation may be a shooting operation, the first application may also be a timely communication application, and the designation operation may be a video call based on a timely communication software. For convenience of description, the preset application is collectively referred to as a first application.
In order to prevent the situation that when the preset application executes the designated operation, the speed of the preset application is slowed down or the preset application is blocked when the preset application executes the designated operation due to the fact that the memory recovery triggered only when the terminal is not enough in free memory available for use, in one embodiment, the method and the device for executing the designated operation can trigger and determine the memory prediction value required to be consumed when the first application executes the designated operation in advance when the first application is started. And if the fact that the first application meets a memory recovery condition when the first application executes the specified operation is determined according to a memory predicted value which needs to be consumed when the first application executes the specified operation, the terminal is triggered to recover the memory occupied by other applications different from the first application so as to ensure the timeliness of memory recovery and meet the memory consumption when the first application executes the specified operation.
The predicted value of the memory to be consumed when the first application executes the designated operation may be preset, and an empirical value of the memory to be consumed when the first application executes the designated operation.
In step S12, if it is determined that the first application satisfies the memory recycling condition when executing the specified operation according to the memory prediction value, the terminal is triggered to recycle the memory occupied by the other applications different from the first application.
In one embodiment, for example, it may be determined that the first application satisfies the memory reclamation condition when executing the specified operation as follows:
and acquiring a memory value required to be reserved by the terminal and a residual memory value of the terminal, and determining a memory value actually required to be occupied by the terminal according to the memory predicted value and the memory value required to be reserved by the terminal. And determining that the first application satisfies the memory recovery condition when executing the specified operation according to the memory value actually occupied by the terminal and the residual memory value of the terminal.
In order to ensure the reasonable allocation of the memory usage, the terminal needs to reserve some idle memory values for subsequent other applications or terminal systems after allocating the idle part of the memory to the first application. The remaining memory value of the terminal can be understood as the memory value of the terminal except the memory value actually occupied.
And comparing the memory value actually occupied by the terminal with the residual memory value of the terminal, and determining that the first application satisfies the memory recovery condition when executing the specified operation if the memory value actually occupied by the terminal is larger than the residual memory value of the terminal. And when the first application executes the designated operation, enough free memory is available in the terminal, so that the designated operation can be smoothly executed by the preset application.
When the terminal is triggered to recycle the occupied memory, for example, the following modes can be used for realizing:
acquiring other applications running in the terminal background, and sequentially recycling the memories of the other applications running in the terminal background according to the priority of the applications running in the terminal background and the sequence of the priority from low to high.
In the exemplary embodiment of the disclosure, when the preset application is started, a memory predicted value which needs to be consumed when the preset application executes the designated operation is obtained, if it is determined that the preset application executes the designated operation according to the memory predicted value which needs to be consumed when the preset application executes the designated operation and a memory recovery condition is met, the terminal is triggered to recover the memory occupied by other applications different from the first application, the timeliness of terminal memory recovery is ensured, when the preset application executes the designated operation, the preset application is ensured to be capable of smoothly executing the designated operation, and the speed of executing the designated operation is increased.
Fig. 2 is a flowchart illustrating a memory reclamation method according to an exemplary embodiment, where as shown in fig. 2, the memory reclamation method is used in a terminal and includes the following steps.
In step S21, in response to the first application starting, a predicted value of the memory that needs to be consumed when the first application performs the specified operation is determined.
In step S22, if it is determined that the first application satisfies the memory recycling condition when executing the specified operation according to the memory prediction value, the terminal is triggered to recycle the memory occupied by the other applications different from the first application.
In step S23, the first application is controlled to perform a specified operation.
In the disclosure, when a first application is started, by determining a memory predicted value that needs to be consumed when the first application executes a specified operation, and if the memory predicted value that needs to be consumed when the first application executes the specified operation is determined, it is determined that the first application satisfies a memory recovery condition when executing the specified operation, and the terminal is triggered to recover a memory occupied by another application different from the first application, so as to ensure timeliness of memory recovery and satisfy memory consumption when the first application executes the specified operation.
Furthermore, because the free memory available for the terminal is enough to meet the memory consumption of the first application when the first application executes the designated operation, when the preset application executes the designated operation, the first application can be controlled to execute the designated operation without triggering the terminal again to recover the memory, so that the speed of executing the designated operation by the first application is increased, and the first application can be ensured to smoothly execute the designated operation.
In the exemplary embodiment of the disclosure, when the first application is started, a memory predicted value which needs to be consumed when the first application executes the designated operation is obtained, if it is determined that the first application executes the designated operation according to the memory predicted value which needs to be consumed when the first application executes the designated operation, and a memory recovery condition is met, the terminal is triggered to recover a memory occupied by other applications different from the first application, so that timeliness of memory recovery of the terminal is ensured, when the preset application executes the designated operation, the preset application can be ensured to smoothly execute the designated operation, and speed of executing the designated operation is increased.
The present disclosure will be described below with reference to an example in which the first application is a camera application and a designated operation is a shooting operation performed by an imaging device mounted in a terminal.
At present, camera devices have become a must of terminal manufacturers. In order to pursue high-quality imaging, various excellent software and hardware technologies are developed, and a high-pixel camera is configured in a terminal, and an image quality record of a shot image is continuously refreshed by assisting excellent image algorithms such as noise reduction, anti-shake and super-resolution. Meanwhile, various applications compete more and more seriously for important system resources such as a CPU and a memory, and when a camera device shoots, because a terminal has insufficient free memory available for use, memory recovery is triggered, so that when the camera application executes shooting operation through the camera device, imaging speed is slow and imaging delay is caused.
Fig. 3 is a schematic diagram illustrating processing of captured image data when a camera application performs a capturing operation by an image capturing apparatus installed in a terminal according to an exemplary embodiment.
In fig. 3, after the camera application performs a photographing operation by the image pickup device installed in the terminal, the image data is subjected to various kinds of arithmetic processes shown in fig. 3, such as Demosaic, MFNR, BOKEH, SR, and the like. When various algorithms process image data, hardware resources such as BPS, IPE, GPU, CDSP and the like are repeatedly utilized to process the image data.
Therefore, when the camera application executes the shooting operation, the consumed memory resource of the terminal is more, and when the camera application executes the shooting operation, the terminal is triggered to carry out memory recovery due to insufficient free memory available for the terminal, and after the memory recovery of the terminal is finished, the terminal carries out various processing on the shot image, so that the imaging speed is low, and the imaging delay is caused.
Fig. 4 is a flowchart illustrating a memory recycling method according to an exemplary embodiment, where as shown in fig. 4, the memory recycling method is used in a terminal, and the terminal is equipped with an image capturing device, and the memory recycling method includes the following steps.
In step S31, in response to the camera application starting, a predicted value of memory that needs to be consumed when the camera application performs a photographing operation by an image pickup device installed in the terminal is determined.
Because the camera application occupies less terminal memory resources in the starting process, when the camera application is received to be started, for example, when the camera application is located in a terminal desktop starter and a Launcher is started, a memory prediction value required to be consumed when the camera application executes shooting operation through a camera device installed in the terminal is determined according to the size of memory required to be consumed when the camera application executes shooting operation. And determining that the camera application satisfies a memory recovery condition when executing the shooting operation through the camera device installed in the terminal according to a memory predicted value required to be consumed when the camera application executes the shooting operation through the camera device installed in the terminal, and triggering the terminal to recover a memory occupied by other applications different from the camera application when the camera application is located in a terminal desktop starter and the camera Launcher is started so as to satisfy the memory consumption when the camera application subsequently needs to execute the shooting operation through the camera device installed in the terminal.
In step S32, if it is determined that the memory recovery condition is satisfied when the camera application performs a shooting operation by an image pickup device installed in the terminal according to the memory prediction value, the terminal is triggered to recover the memory occupied by another application different from the camera application.
In one embodiment, for example, it may be determined that the memory recovery condition is satisfied when the camera application performs a shooting operation by an imaging device installed in the terminal as follows:
obtaining the memory value which is determined based on the terminal operating system and needs to be reserved by the terminal, for example, recording as MreservedAnd the remaining memory value of the terminal is noted as MleftAccording to a memory prediction value, for example, denoted as McaptureAnd the memory value M required to be reserved by the terminalreservedDetermining the memory value actually occupied by the terminal, e.g. as Mtarget. According to the memory value M occupied by the terminal actual needtargetAnd the remaining memory value M of the terminalleftAnd determining that the camera application meets the memory recovery condition when executing shooting operation through a camera device installed in the terminal.
According to the memory value M occupied by the terminal actual needtargetAnd the remaining memory value M of the terminalleftFor example, it may be determined that the memory recovery condition is satisfied when the camera application performs a photographing operation by an image pickup device installed in the terminal, as follows:
comparison MtargetAnd MleftIf M is large or smalltarget>MleftAnd determining that the camera application meets the memory recovery condition when executing shooting operation through a camera device installed in the terminal.
Furthermore, when the camera application meets the memory recovery condition when the camera application executes the shooting operation through the camera device installed in the terminal, the terminal is triggered to recover the memory occupied by other applications different from the camera application, so that enough free memory is provided for the camera application before the camera application executes the shooting operation through the camera device installed in the terminal, the camera application can smoothly execute the shooting operation, the imaging speed of the shot image is increased, and imaging delay is avoided.
In the exemplary embodiment of the disclosure, when the camera application is started, a memory predicted value that needs to be consumed when the camera application executes a shooting operation is obtained, if it is determined that the preset application executes the specified operation according to the memory predicted value that needs to be consumed when the preset application executes the specified operation and a memory recovery condition is met, the time for recovering the memory is advanced to the time when the camera application is started, the timeliness of memory recovery is ensured, the processing speed of image data after shooting is further ensured, the imaging speed of the shot image is increased, and imaging delay is avoided.
Based on the same conception, the embodiment of the disclosure also provides a memory recovery device.
