[0033] Combination Figure 1 As shown, the embodiment of the present disclosure provides an interface switching method for an RTOS system, which is applied to a terminal device. The method includes:

[0034] S01, the terminal device obtains an interface update request, which carries the storage address information of the original image and the target sequence number information of the target update image.

[0035] S02, the terminal device obtains a data packet, the data packet stores addressing information associated with the original picture, the addressing information includes sequence number information associated with the updated picture and differential data information associated with the sequence number information.

[0036] In this step, the differential data represents data corresponding to the portion where the updated image differs from the original image. It can be understood that the differential data may be one or more. The number of differential data is determined by the difference between the updated image and the original image.

[0037] S03, the terminal device matches the target differential data information associated with the target sequence number information from the data packet.

[0038] S04, the terminal device updates the original image to the target updated image according to the target differential data information and the storage address information.

[0039] Using the interface switching method for RTOS system provided by the embodiment of the present disclosure, the terminal device obtains the storage address information of the original image and the target sequence number signal of the target updated image according to the interface update request. The terminal device matches the target differential data associated with the target sequence number information from the data packet and updates the image according to the target differential data and the storage address information. The data stored in the data packet obtained by the terminal device is the differential data associated with the sequence number information, and not all the image data associated with the updated image is stored, which reduces the storage space occupied and improves the efficiency of interface update.

[0040] Optionally, the differential data information includes an offset address, differential segment data, and the data volume of the differential data associated with the differential data. As an example, the differential segment data is one. Accordingly, the differential data information includes an offset address, the data volume of the differential segment data, and the differential segment data corresponding to the differential data with continuous addresses.

[0041] Combination Figure 2 As shown, according to the target differential data information and the storage address information, the original image is updated to the target update image, including:

[0042] S11, the terminal device determines the target offset address, target differential segment data and target data volume from the target differential data information.

[0043] In this step, the offset address associated with the differential data indicates the address offset of the differential segment data relative to the starting address of the original image. The data volume of the differential data indicates the data length of the differential data. The terminal device can determine the target offset address, target differential segment data and target data volume through the target differential data information.

[0044] S12, the terminal device determines the target update start and end positions according to the storage address information, the target offset address and the target data volume.

[0045] In this step, the update start and end positions include the update start address and the update end address. Since the offset address represents the address offset of the differential segment data relative to the start address of the original image, the terminal device can accurately obtain the target update start address and the target update end address according to the storage address information, target offset address and target data volume of the original image, thereby improving the accuracy of the interface update.

[0046] S13, the terminal device updates the data corresponding to the target update start and end positions into the target differential segment data.

[0047] In this way, the terminal device can update the original image to the target update image after accurately determining the start and end positions of the target update, thereby improving the accuracy and efficiency of the interface update.

[0048] Optional, combined Figure 3 As shown, according to the storage address information, the target offset address and the target data volume, the target update start and end positions are determined, including:

[0049] S21, the terminal device determines the target update starting position according to the storage address information and the target offset address.

[0050] S22, the terminal device determines the target update end position according to the target data volume, so as to update the data corresponding to the target update start position and the target update end position into the target differential segment data.

[0051] In this way, the terminal device determines the target update starting position according to the storage address information and the target offset address, and determines the target update ending position according to the target data volume. Then, the data corresponding to the target update starting position and the target update ending position are updated as target differential segment data. This method accurately determines the position corresponding to the target differential segment data according to the target update starting position and the target update ending position, and finally updates the target differential segment data. This method does not need to replace or update all the data at the storage address information of the original data, thereby improving the efficiency of interface switching.

[0052] Combination Figure 4 As shown, the embodiment of the present disclosure also provides an interface switching method for an RTOS system, which is applied to a terminal device. The differential data information includes an offset address associated with the differential data, differential segment data, the data volume of the differential data, a start address associated with the differential data, and the data volume of the differential data. The method includes:

[0053] S31, the terminal device obtains an interface update request, which carries the storage address information of the original picture and the target sequence number information of the target update picture.

[0054] S32, the terminal device obtains a data packet, the data packet stores addressing information associated with the original picture, the addressing information includes sequence number information associated with the updated picture and differential data information associated with the sequence number information.

[0055] S33, the terminal device matches the target differential data information associated with the target sequence number information from the data packet.

[0056] S34, the terminal device determines the target starting address and target data volume of the target update picture from the target differential data information.

[0057] S35, the terminal device obtains a target reading position associated with the target differential data according to the target starting address and the target data volume, so as to determine a target offset address and target differential segment data from the target reading position.

[0058] In this step, before determining the start and end positions of the target update, the terminal device needs to obtain the target offset address and target differential segment data associated with the target differential segment data. To this end, the differential data information includes the start address associated with the differential data and the data volume of the differential data. The terminal device can determine the target start address and target data volume of the target update image by reading the target differential data information, thereby obtaining the target read position associated with the target differential data, and then determining the target offset address and target differential segment data from the target read position. In the above manner, the target read position corresponding to the target differential data can be accurately determined, further improving the efficiency of interface switching.

[0059] S36, the terminal device determines the target offset address, target differential segment data and target data volume from the target differential data information.

[0060] S37, the terminal device determines the target update start and end positions according to the storage address information, the target offset address and the target data volume.

[0061] S38, the terminal device updates the data corresponding to the target update start and end positions into the target differential segment data.

[0062] By adopting the interface switching method for RTOS system provided by the embodiment of the present disclosure, the terminal device can accurately obtain the target reading position corresponding to the target differential data, thereby obtaining the target offset address, target differential segment data and target data amount according to the target reading position, and then perform an update operation on the target differential segment data, thereby further improving the efficiency of interface switching.

[0063] Optionally, in the case where the differential segment data includes multiple, the differential data information also includes the number of segments associated with the differential data. The terminal device updates the original image to the target updated image according to the target differential data information and the storage address information, and also includes:

[0064] The terminal device determines the target offset address, target data volume and differential segment data of each target differential segment data from the target differential data information, so as to determine the target update start and end positions corresponding to each differential segment data and perform data update.

[0065] In this way, when there are multiple differential segment data due to the large difference between the original image and the updated image, the terminal device determines the target offset address of each target differential segment data, the target data volume of each target differential segment data, and each differential segment data, thereby determining the target update start and end positions corresponding to each differential segment data and performing data update. On the basis of improving the efficiency of interface switching, the reliability of interface switching is improved.

[0066] As an example, there are two differential segment data, namely 1# differential segment data and 2# differential segment data. The differential segment data information also includes the number of segments of the differential segment data. Specifically, the differential data information includes the number of segments of the differential segment data, the offset address associated with each differential data, each differential segment data, and the data volume of each differential data. Correspondingly, the differential data information includes the offset address corresponding to the 1# differential segment data with continuous addresses, the data volume of the 1# differential segment data, the 1# differential segment data, the offset address corresponding to the 2# differential segment data, the data volume of the 2# differential segment data, and the 2# differential segment data. It should be noted that in the case where there are multiple differential segment data, the offset address, differential segment data, and the data volume of the differential data associated with any differential segment data are stored continuously in the storage space.

[0067] Combination Figure 5 As shown, the embodiment of the present disclosure also provides an interface switching method for an RTOS system, which is applied to a terminal device. The method includes:

[0068] S41, the terminal device obtains an interface update request, which carries the storage address information of the original image and the target sequence number information of the target update image.

[0069] S42, the terminal device obtains a data packet, the data packet stores addressing information associated with the original picture and a preset storage address of the original picture, the addressing information includes sequence number information associated with the updated picture and differential data information associated with the sequence number information.

[0070] S43, the terminal device determines whether the storage address information of the original image matches the preset storage address, if so, executes S44, if not, returns to execute S41.

[0071] In this step, the storage address information of the original image matches the preset storage address, including that the storage address information of the original image is the same as the preset storage address.

[0072] S44, the terminal device matches the target differential data information associated with the target sequence number information from the data packet.

[0073] S45, the terminal device updates the original picture to the target updated picture according to the target differential data information and the storage address information.

[0074] By using the interface switching method for RTOS system provided by the embodiment of the present disclosure, the terminal device matches the storage address information of the original picture in the interface update request with the preset storage address stored in the data packet. When the match is successful, it indicates that the interface of the original picture at the storage address information needs to be updated, and then the subsequent target differential data acquisition step and picture update step are performed. This method can avoid performing erroneous update operations on the original picture and improve the reliability of interface updates.

[0075] Combination Figure 6 As shown, the embodiment of the present disclosure also provides an interface switching method for an RTOS system, which is applied to a terminal device. The method includes:

[0076] S51, the terminal device obtains an interface update request, which carries the storage address information of the original picture and the target sequence number information of the target update picture.

[0077] S52, the terminal device obtains a data packet, which stores the addressing information associated with the original picture, the preset storage address of the original picture, the verification information, and the number of original pictures. The addressing information includes the sequence number information associated with the updated picture and the differential data information associated with the sequence number information. The verification information represents the sum of the preset storage address, the current number of original pictures, and the data volume of the addressing information.

[0078] S53, the terminal device obtains storage address information, addressing information, and the target and value of the current number of original pictures.

[0079] S54, the terminal device determines whether the target sum value matches the sum value, and if so, executes S55.

[0080] S55, the terminal device determines whether the storage address information of the original image matches the preset storage address, if so, executes S56, if not, returns to execute S51.

[0081] S56, the terminal device matches the target differential data information associated with the target sequence number information from the data packet.

[0082] S57, the terminal device updates the original picture to the target updated picture according to the target differential data information and the storage address information.

[0083] Using the interface switching method for an RTOS system provided by an embodiment of the present disclosure, the data packet stores verification information, which represents the sum of the preset address, the current number, and the data volume of the addressing information. The terminal device sums the storage address information, the addressing information, and the current number of original images to obtain a target sum value, compares the target sum value with the sum value, and can verify the current number of original images to find out whether the number of original images in the data packet is correct. After determining that the number of original images is correct, the terminal device verifies the storage address information of the original images, thereby avoiding performing erroneous update operations on the original images and improving the reliability of interface updates.

[0084] Optional, combined Figure 7 As shown, before updating the original image to the target updated image according to the target differential data information and the storage address information, the method further includes:

[0085] S61, the terminal device obtains the starting address of the picture running area, the data of the original picture and the current data volume.

[0086] S62, the terminal device updates the data corresponding to the area in the picture running area with the starting address as the starting position and the address offset matching the current data amount as the data of the original picture.

[0087] In this step, the data packet is stored in the picture storage area.

[0088] In this way, the update operation of the picture is only completed in the picture running area, and will not affect the storage of the data of the original picture. And, after the terminal device reads the relevant data stored in the data packet stored in the picture storage area, it updates the data in the corresponding area of ​​the picture running area associated with the terminal device, so as to load the data according to the target differential data and the storage address information, thereby quickly performing the update operation of the original picture.

[0089] It can be understood that the above-mentioned terminal device obtains the starting address of the picture running area, the data of the original picture and the current data amount, and updates the data corresponding to the area in the picture running area with the starting address as the starting position and the address offset matching the current data amount to the data of the original picture. The step can be performed before obtaining the data packet, or it can be executed simultaneously with obtaining the data packet, and the implementation of the present disclosure does not make specific limitations on this.

[0090] In actual application, as shown in Table 1 and Table 2, the number of original pictures is 1. The storage address of the original picture is 0x00008000, and the data size of the original picture is 16 bytes. Specifically, the data of the original picture is 0x00 0x01 0x020x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A 0x0B 0x0C 0x0D 0xE 0x0F. The starting address of the picture running area is 0x10000000.

[0091] Table 1 Data Packet

[0092]

[0093] Table 2 Differential data

[0094]

[0095] In Table 2, the starting address of the original picture indicates the starting address of the original picture loaded into the picture running area.

[0096] First, the mobile phone obtains an interface update request, which carries the storage information of the original picture and the target sequence number information of the target update picture. The target sequence number information is 1#. Specifically, the mobile phone obtains the starting address 0x10000000 associated with the original picture, the sequence number information 1# of the update picture, and the 1# differential data information from the data packet stored in the picture storage area (Table 1).

[0097] Secondly, the mobile phone reads the target offset address 0x00000010, the target differential segment data and the target data volume 0x00000005 corresponding to the 1# differential data information from Table 2.

[0098] Again, the mobile phone loads the original picture. Specifically, the data of 16 bytes starting with 0x10000000 (the data amount of the original picture) in the picture running area is updated to the data of the original picture 0x00 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A 0x0B 0x0C 0x0D 0xE 0x0F.

[0099] Subsequently, the mobile phone determines the target update start position as the position with the target offset address relative to the start address and the target update end position as the position with the target data amount offset from the target update start position based on the start address 0x10000000, the target offset address 0x00000010 and the target data amount 0x00000005.

[0100] Finally, the mobile phone replaces the data at the starting address 0x10000000 of the picture running area, the target update starting position and the target update ending position with the differential segment data 0x01 0x02 0x03 0x04 0x05. After the above update, the data in the picture running area is updated to 0x00 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x01 0x020x03 0x04 0x05 0xE 0x0F. Thus, the original picture is updated to the target update picture.
