Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Aiming at the problem of slow starting-up speed of the video processing device, it is found that at present, when the video processing device is started up, pictures such as background pictures (BKG) or LOGO pictures (LOGO, icon or label) stored in a non-volatile memory such as a Flash memory of the video processing device need to be fully loaded into a volatile memory such as DDR (Double Data Rate) memory of the video processing device. However, because of the large and large number of these pictures, the process of loading the pictures into DDR memory is time consuming and can even consume a significant portion of the on-time of the video processing device. Based on the above, the embodiment of the invention provides a picture loading method to solve the problem of slow starting-up speed of video processing equipment.
[ First embodiment ]
Referring to fig. 1, a picture loading method according to a first embodiment of the present invention is shown. The picture loading method is applicable to a processor of a video processing device, the video processing device further comprises a volatile memory and a nonvolatile memory which are respectively electrically connected with the processor, and the picture loading method comprises the following steps:
S10, reading and analyzing the current scene file stored in the nonvolatile memory to obtain a target identification information set of a target display picture set;
s11, traversing the picture set stored in the nonvolatile memory, and loading the target display picture set corresponding to the target identification information set in the picture set to the volatile memory.
It should be noted that the current scene file is corresponding configuration information stored in the video processing device when the video processing device is used by the user last time, where the configuration information includes, but is not limited to, layout information of a picture, for example, a background picture (BKG), and identification information, for example, a picture name. The target display picture set is a picture corresponding to a picture name included in the current scene file, namely a picture required to be used by the current scene file. The target display picture set may include one or more pictures, and embodiments of the present invention are not specifically limited herein. In addition, the traversing is performed according to the storage sequence of the pictures in the picture set in the nonvolatile memory, for example, but the embodiment of the invention is not limited thereto.
In order to facilitate understanding of the present invention, a picture loading method according to an embodiment of the present invention will be described in detail with reference to fig. 2 to 6. The picture loading method of embodiments of the present invention may, for example, run on a video processing device 20 (shown in fig. 6) that includes a processor 22. The video processing device 20 further comprises a volatile memory 21 and a non-volatile memory 23 electrically connected to the processor 22, respectively. The non-volatile memory 23 is, for example, a Flash memory, the volatile memory 21 is, for example, a DDR memory, and the processor 22 is, for example, an MCU (Microcontroller Unit, micro control unit) or ARM (Advanced RISC Machine) processor, but the embodiment of the present invention is not limited thereto.
When the picture loading method is executed, as shown in fig. 1, the processor 22 first reads and parses the current scene file stored in the nonvolatile memory 23 to obtain a target identification information set of a target display picture set; then traversing the picture set stored in the nonvolatile memory 23, and loading the target display picture set corresponding to the target identification information set in the picture set to the volatile memory 21. The target identification information set is, for example, a picture name of a target display picture set. According to the scheme, by traversing the picture set stored in the nonvolatile memory 23 and loading the target display picture set corresponding to the target identification information set in the picture set to the volatile memory 21, only the target display picture set corresponding to the current scene file is loaded to the volatile memory 21 during starting, so that the starting speed of the video processing device 20 is increased, and the user experience is improved.
The picture set comprises a first picture; as shown in fig. 2, the step S11 specifically includes: s110, the processor 22 reads first picture identification information of the first picture (for example, a name of the first picture); s111, judging whether first target identification information matched with (for example, identical to) the first picture identification information exists in the target identification information set; and S112, in response to the presence of the first target identification information matching the first picture identification information in the target identification information set, the processor 22 loads the first picture into the volatile memory 21.
In view of the foregoing, as shown in fig. 3, the image loading method further includes: s113, the processor 22 determines whether to traverse the picture set stored in the nonvolatile memory 23 in response to the target identification information set not having the first target identification information matched with the first picture identification information; s114, the processor 22 reads second picture identification information (for example, a name of a second picture) of the picture set in response to the picture set stored in the non-volatile memory 23 not being traversed; s115, the processor 22 determines whether there is second target identification information matching the second picture identification information in the target identification information set; and S116, in response to the second target identification information matching the second picture identification information being present in the target identification information set, the processor 22 loads the second picture into the volatile memory 21.
In view of the foregoing, as shown in fig. 4, the image loading method further includes: s117, the processor 22 obtains layout information of the target display picture set according to the current scene file in response to traversing the picture set stored in the nonvolatile memory 23; s118, the processor 22 reads the target display picture set in the volatile memory 21, and displays the target display picture set according to the layout information, so that the video processing apparatus can operate normally; s119, during normal operation of the video processing apparatus, the processor 22 acquires an unloaded picture that is not loaded into the volatile memory 21 in the nonvolatile memory 23, and loads the unloaded picture into the volatile memory 21. In this scheme, the pictures, which are not needed by the current scene file, in the picture set stored in the non-volatile memory 23 are loaded into the volatile memory 21 during the normal operation of the video processing device 20, so that the user can use the pictures during the normal operation of the video processing device 20, and thus, only the pictures needed by the current scene file are loaded during the startup, and other pictures are loaded into the volatile memory 21 after the normal operation of the video processing device 20, thereby improving the startup speed, and meanwhile, the user can not be influenced to use other pictures, and thus improving the user experience.
In the above, step S11 further includes: each target display picture corresponding to the target display picture set in the non-volatile memory 23 is marked as a loaded picture, where the marking process may set a loading flag field for a picture, and after the picture is loaded into the volatile memory 21, the processor 22 sets a value corresponding to the loading flag field to 1, or may set other values as long as it can indicate that the picture has been loaded into the volatile memory 21.
As shown in fig. 5, the step S119 specifically includes: s1190, in response to reaching the load permission time, determining whether the target picture in the nonvolatile memory 23 is a loaded picture, where it is determined whether the target picture is a loaded picture, for example, by determining whether a load flag field of the target picture is 1; s1191, in response to the target picture being an unloaded picture, loading the target picture into the volatile memory 21, marking the target picture as a loaded picture; s1192, determining whether each picture in the nonvolatile memory 23 is loaded into the volatile memory; and S1193, in response to each picture in the nonvolatile memory 23 being loaded into the volatile memory 21, no picture loading process is performed, or in response to there being another picture in the nonvolatile memory 23 that is not loaded into the volatile memory 21, updating the loading permission time. It should be noted that the loading permission time may be determined by the processor 22 according to a user-defined detection period, for example, by executing the loading process of fig. 5 every 5 minutes after the video processing apparatus 20 is normally operated. Furthermore, the target picture is a picture in the picture set in the nonvolatile memory 23, and the loading process is performed, for example, according to the sequence of the pictures stored in the nonvolatile memory 23 corresponding to the storage addresses, for example, the first picture stored in the nonvolatile memory 23 is first determined, the first picture is the current target picture, and after the first picture is subjected to the relevant determination or processing, the next picture, that is, the second picture is the target picture at this time. Here, the loading permission time is set to periodically load the pictures which are not loaded in the volatile memory 21 in the nonvolatile memory 23, so that the video processor 20 is not blocked, thereby improving the user experience.
In addition, before the processor 22 executes step S11, a loading environment preparation is performed, which includes, but is not limited to, initialization of the IO/DDR/FPGA, which is common knowledge in the technical field of video processing devices, and the embodiment of the present invention is not specifically described herein.
In summary, according to the picture loading method in the embodiment of the present invention, by traversing the picture set stored in the non-volatile memory and loading the target display picture set corresponding to the target identification information set in the current scene file in the picture set to the volatile memory, only the target display picture set corresponding to the current scene file is loaded to the volatile memory during startup, so that startup speed of the video processing device is increased, and user experience is improved.
