With the increase in the number of reads and writes of the non-volatile memory and the influence of external environmental factors, the probability of abnormal system data on the non-volatile memory will gradually increase. Once the system data on the non-volatile memory is abnormal When this happens, the terminal device will be unusable and the service life of the terminal device will be reduced. In addition to causing inconvenience in use, it will also increase maintenance costs.

In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a data processing method for a terminal device. The terminal device stores identical first system data and second system data, wherein the first system data includes multiple a first data block, and the second system data includes a plurality of second data blocks, and the first data blocks correspond to the second data blocks respectively. The data processing method includes: sequentially loading the first data blocks of the first system data; each time the first data block of the first system data is loaded, detecting whether the first data block of the first system data is damaged; When the first data block of the first system data is damaged, record the damage information in the storage unit; detect whether the second data block corresponding to the damaged first data block in the second system data is damaged; and when the second data block is not damaged When damaged, load the second data block.

In order to solve the above technical problems, another technical solution adopted by the present invention is a data processing system of a terminal device, which includes a memory and a processor. The memory stores exactly the same first system data and second system data, wherein the first system data includes a plurality of first data blocks, and the second system data includes a plurality of second data blocks, and the first data blocks are respectively Corresponding to these second data blocks. The processor is electrically connected to the memory, and the processor is used to trigger the start-up phase of the terminal device, and the start-up phase includes: sequentially loading the first data blocks of the first system data; When a data block is detected, it is detected whether the first data block of the first system data is damaged; when the first data block of the first system data is damaged, the damage information is recorded in the storage unit; the second system data and the damaged first data block are detected Whether the second data block corresponding to the data block is damaged; and when the second data block is not damaged, load the second data block.

In order to solve the above-mentioned technical problems, another technical solution adopted by the present invention is a data processing method for a terminal device, where the terminal device stores exactly the same first system data and second system data. The data processing method includes: triggering an abnormality detection mechanism in the startup phase; judging whether the first system data selected as the loading target is successfully loaded; when it is confirmed that the first system data is successfully loaded, entering the running phase; triggering the data repair mechanism in the running phase ; Judging whether the damaged data block repaired in the data repair mechanism belongs to the running first system data; when the repaired damaged data block belongs to the running first system data, a switching mechanism is triggered; and when the repaired damaged data block The data block does not belong to the running first system data, exit the data recovery mechanism.

One of the beneficial effects of the present invention is that, through the data processing system of the terminal device and the data processing method of the terminal device provided by the present invention, the position of the damaged point can be detected accurately and quickly, reducing unnecessary erasure and saving time for repairing . Since the state of the first system data and the second system data will be detected during the start-up phase and the running phase, the position of the damaged point can be detected in real time, and the time for abnormal operation can be reduced. The data recovery mechanism provides power-off protection, supports power-off continuous recovery, and prolongs the service life of the terminal device. When the first system information in use of the terminal device is abnormal, after confirming that the second system information is complete, the first system information in use can be switched to the second system information. Similarly, when the second system information in use of the terminal device is abnormal, after confirming that the first system information is complete, the second system information in use can be switched to the first system information. In this way, the lifetime of the system data in the memory is extended. Furthermore, when the life of the memory reaches the limit and cannot be repaired, and the corresponding data blocks of the first system data and the second system data are damaged at the same time, the loading mechanism in the startup phase of the present invention can still ensure the safety of the terminal device.

FIG. 1 is a functional block diagram of a data processing system of a terminal device according to an embodiment of the present invention. As shown in Figure 1, the terminal device 1 includes a processor 11 and a memory 13, and the memory 13 is electrically connected to the processor 11, and the memory 13 is a non-volatile memory, such as Nor Flash or Nand Flash, so Even in a power-off state, the data stored in the memory 13 will not be lost. The memory 13 is provided with a storage unit 131 and stores the first system data A and the second system data B, the first system data A and the second system data B are the same.

FIG. 2 is a schematic diagram of storing system data and backup system data in memory in FIG. 1 . Referring to FIG. 1 and FIG. 2 together, the first system data A includes a plurality of first data blocks A1˜AN, and the second system data B includes a plurality of second data blocks B1˜BN. The first data blocks A1-AN respectively correspond to the second data blocks B1-BN and are respectively stored in different memory locations of the memory 13, which means that the contents of the first data blocks A1-AN are respectively the same as Contents of the second data blocks B1-BN. In this embodiment, the first data blocks A1~AN correspond to different loading sequences 1~N, and the second data blocks B1~BN respectively correspond to different loading sequences 1~N, and the loading sequence does not follow this As long as it meets the principle that all data blocks need to be loaded. For example, assuming N=50, multiple first data blocks A1~A20 correspond to loading sequences 1~20 respectively, multiple second data blocks B1~B20 respectively correspond to loading sequences 1~20, and multiple first data blocks A41 ~A50 corresponds to loading sequence 21~30 respectively, multiple second data blocks B41~B50 correspond to loading sequence 21~30 respectively, multiple first data blocks A21~A40 correspond to loading sequence 31~50 respectively, and multiple second data blocks Blocks B21~B40 correspond to loading sequences 31~50 respectively.

FIG. 3 is a flowchart of a data processing method of a terminal device according to an embodiment of the present invention. As shown in FIG. 3 , in step S301 , an abnormality detection mechanism in the start-up phase (also called the power-on phase) is triggered. In detail, when the terminal device is turned on, it immediately detects whether there is a damaged data block in the system data selected as the loading target, and when it is found that there is a damaged data block in the system data selected as the loading target, load it from another system data. The data block corresponding to the damaged data block, for example, the first system data is selected as the loading target, and when the first data block with the loading order of 3 in the first system data is detected to be damaged, try to load the order from the second system data The second data block for 3 is loaded. In step S303, it is judged whether the system data selected as the loading target is successfully loaded, that is, whether the terminal device is started successfully. When it is confirmed that the system information selected as the loading target is successfully loaded, it means that the terminal device is started successfully, and then step S305 is executed. In step S305, an abnormality detection mechanism in the running phase is triggered. When it is confirmed that the system data selected as the loading target has not been successfully loaded, then step S307 is executed. In step S307, the terminal device fails to start.

After step S305, step S309 is then executed. In step S309, it is detected whether the state of the running system data is abnormal. When it is confirmed that the state of the running system data (also referred to as the system data in use) is abnormal, then step S311 is executed. In step S311, the switching mechanism is triggered. When the status of the running system data is not abnormal, return to step S305. For example, after the terminal device 1 enters the running phase, if it detects that the status of the data block in the running system data is abnormal and cannot be used at the first point in time, the switching mechanism will be triggered. If no abnormality is detected in the state of the running system data at the first time point, the state of the running system data is continuously detected, and if an abnormal state of the data block of the running system data is detected at the second time point , the switching mechanism is triggered.

After the switching mechanism is triggered, then return to step S301, which means that the terminal device 1 is restarted and enters the startup phase again. For example, when the terminal device enters the startup phase for the first time, the first system data is used as the loading target, and after the switching mechanism is triggered, the terminal device enters the startup phase for the second time, and at this time the second system data is used as the loading target.

In step S303, when it is confirmed that the system data selected as the loading target is successfully loaded, then step S313 is executed, and in step S313, a data recovery mechanism is triggered. In step S315, it is determined whether one or more damaged data blocks repaired in the data repair mechanism belong to running system data. When it is confirmed that the one or more damaged data blocks to be repaired belong to the running system data, step S311 is executed. When it is confirmed that the repaired one or more damaged data blocks do not belong to the running system data, step S317 is executed. In step S317, the data recovery mechanism is exited. For example, if it is confirmed that the repaired damaged data block belongs to the running first system data A, the switching mechanism is triggered, and then the terminal device 1 is restarted and the second system data B is selected as the loading target. Conversely, if the damaged data block to be repaired belongs to the second system data B instead of the running first system data A, the data repair mechanism is exited. In addition, the execution sequence of step S305 and step S313 is not limited.

FIG. 3 is the overall flow of an embodiment of the data processing method of the present invention. The anomaly detection mechanism in the start-up phase, the anomaly detection mechanism in the running phase, the data restoration mechanism, and the switching mechanism will be described in detail later.

FIG. 4 is a flow chart of the anomaly detection mechanism in the startup phase of FIG. 3 . As shown in FIG. 4 , in step S401 , the storage unit 131 of the memory 13 is read. In detail, each time the terminal device 1 enters the startup phase, it first reads the information of the storage unit 131 . In step S403, according to the information of the storage unit 131, one of the first system data A and the second system data B is selected as a loading target. When it is confirmed that the first system data A is selected as the loading target, then step S405 is executed. In step S405, a data block corresponding to a loading sequence in the first system data A is loaded. For example, when the first system data A is the loading target, the first data block A1 of the first system data A is loaded first, and the loading sequence corresponding to the first data block A1 is 1.

Firstly, the steps after the first system data A is selected as the loading target are described.

After step S405, step S407 is then executed. In step S407, it is detected whether the loading of the first data block of the first system data A fails. When it is confirmed that the loading of the first data block of the first system data A fails, it means that the first data block to be loaded belongs to a damaged data block, and then step S409 is executed. In step S409, record damage information in the storage unit. On the contrary, when it is confirmed that the loading of the first data block of the first system data A is successful, it means that the first data block to be loaded is not damaged, and then step S411 is executed. In step S411, the loading sequence is increased by one, and then step S413 is executed. In step S413, it is determined whether the loading sequence exceeds a threshold value, wherein the threshold value is equal to the total number of the first data blocks in the first system data A. When it is confirmed that the loading sequence does not exceed the critical value, return to step S405. When it is confirmed that the loading sequence has exceeded the critical value, then step S415 is executed. In step S415, the terminal device 1 is started successfully.

For example, when the first data block A1 in the first system data A is damaged and cannot be loaded, the damage information will be recorded in the storage unit 131, wherein the damage information includes the information that the first data block A1 is a damaged data block and its location memory location.

After step S409, step S417 is then performed. In step S417, it is detected whether the second data block corresponding to the damaged data block of the first system data A in the second system data B is damaged. When it is confirmed that the second data block is not damaged, then step S419 is executed. In step S419, the second data block is loaded, and then returns to step S411. For example, when the first data block A1 of the first system data A is detected to be damaged, further check whether the second data block B1 of the second system data B is damaged, and when it is confirmed that the second data block B1 is not damaged, load The second data block B1 continues to detect whether the loading of the first data block A2 of the first system data A fails.

On the contrary, when it is confirmed that the second data block is damaged, then step S421 is executed. In step S421, the terminal device 1 fails to start.

For example, the number of the first data blocks in the first system data A and the number of the second data blocks in the second system data are both N, indicating that the threshold value is N. Firstly, it is detected whether the first data block A1 of the first system data A whose loading sequence is 1 is damaged, and if the first data block A1 is not damaged, the first data block A1 is loaded. Next, change the load order from 1 to 2. When the loading sequence is 2, check whether the first data block A2 of the first system data A is damaged, and when the first data block A2 of the first system data A is not damaged, load the first data block A2 of the first system data A . Similarly, the loading order is continuously increased until the loading order is equal to the total number of the first data blocks of the first system data A, which means that all the first data blocks of the first system data A have been checked.

In step S403, when the second system profile B is selected, then step S423 is executed. In step S423, a second data block corresponding to a loading sequence in the second system data B is loaded. For example, when the second system data B is used as the loading target, the second data block B1 in the second system data B is loaded first, and the corresponding loading order of the second data block B1 is 1.

Next, the steps after the second system data B is selected as the loading target are described.

After step S423, follow step S425. In step S425, it is detected whether the loading of the second data block of the second system data B fails. When it is confirmed that the second data block cannot be loaded, it means that the second data block is a damaged data block, and then step S427 is executed. In step S427, the damage information is recorded in the storage unit 131. For example, when the second data block B1 of the second system data B is damaged, the second data block B1 cannot be loaded, and then the damage information is recorded in the storage unit 131, wherein the damage information includes that the second data block B1 is a damaged data block and its corresponding memory location.

On the contrary, when it is confirmed that the loading of the second data block of the second system data B is successful, it means that the second data block to be loaded is not damaged, and then step S429 is executed. In step S429, the loading order is increased by one, and then step S431 is executed. In step S431, it is determined whether the loading sequence exceeds a threshold value, wherein the threshold value is equal to the total number of the second data blocks in the second system data B. When it is confirmed that the loading sequence does not exceed the critical value, return to step S423. When it is confirmed that the loading sequence has exceeded the critical value, then step S433 is executed. In step S433, the terminal device 1 is started successfully.

After step S427, step S435 is then performed. In step S435, it is detected whether the first data block corresponding to the damaged data block of the second system data B in the first system data A is damaged. When it is confirmed that the first data block is not damaged, then step S437 is executed. In step S437, the first data block is loaded, and then returns to step S429. For example, when the second data block B1 of the second system data B is damaged, it is detected whether the first data block A1 of the first system data A is damaged, and when it is confirmed that the first data block A1 of the first system data A is not damaged, Then load the first data block A1 of the first system data A, and then continue to detect whether the loading of the second data block B2 of the second system data B fails.

On the contrary, when it is confirmed that the first data block in the first system data A corresponding to the damaged data block in the second system data B is damaged, then step S439 is executed. In step S439, the terminal device 1 fails to start.

To sum up, steps S401-S439 are the anomaly detection mechanism in the start-up phase. When the terminal device 1 selects the first system data A as the loading target at the start-up stage, it then performs abnormal detection on the state of each first data block of the first system data A until the state of each first data block is detected. , the terminal device 1 starts up successfully. Similarly, when the terminal device 1 selects the second system data B as the loading target during the start-up phase, then an abnormality detection is performed on the state of each second data block of the second system data B until the state of each second data block is After the detection is completed, the terminal device 1 is started successfully.

The anomaly detection mechanism in FIG. 4 can be implemented by the data processing system 1 in FIG. 1 . In detail, steps S401 - S439 are executed by the processor 11 of the data processing system 1 . However, the anomaly detection mechanism in FIG. 4 can also be executed by other data processing systems, and is not limited to be executed by the data processing system 1 in FIG. 1 .

After the start-up of the terminal device 1 is completed (step S415 or step S433 in FIG. 4 ), then the terminal device 1 enters the running phase and triggers the abnormality detection mechanism of the running phase.

FIG. 5 is a flow chart of the anomaly detection mechanism in the running phase in FIG. 3 , and the first system data A is the running system data as an example below. After step S415 in FIG. 4 , step S501 is executed next. In step S501, an abnormality detection mechanism in the running phase is triggered. In step S503, it is detected whether the state of the running first system data A is abnormal. When it is confirmed that the state of the running first system data A is abnormal, step S505 is executed. In step S505, the damage information of the storage unit 131 is updated. When it is confirmed that the state of the running first system data A is not abnormal, return to step S501. In detail, during the running phase, it is continuously detected whether the state of the first system data A is abnormal, assuming that at the first time point, the state of the first data block A2 of the first system data A is detected as abnormal. Due to the abnormal state of the first data block A2 , it cannot be used, so the damage information about the first data block A2 being a damaged data block is recorded in the storage unit 131 . For example, assuming that no abnormal state of the first system data A is detected at the first time point, it is continuously detected whether the state of the first system data A is abnormal. If it is detected at the second time point that the state of the first data block A5 of the first system data A is abnormal, damage information about the first data block A5 being a damaged data block is recorded in the storage unit 131 .

Similarly, when the running first system profile A is changed to the second system profile B, the main difference is that the first system profile A in step S503 is replaced with the second system profile B.

The anomaly detection mechanism in FIG. 5 can be implemented by the data processing system 1 in FIG. 1 . In detail, steps S501 - S505 are executed by the processor 11 of the data processing system 1 . However, the anomaly detection mechanism in FIG. 5 can also be executed by other data processing systems, and is not limited to be executed by the data processing system 1 in FIG. 1 .

After the terminal device 1 is started (step S415 or step S433 in FIG. 4 ), then the terminal device 1 enters the running phase and triggers the data restoration mechanism in the running phase.

FIG. 6 is a flow chart of the data restoration mechanism in the running phase in FIG. 3 . The following is an example based on the first system information A as the running system information. After step S415 in FIG. 4 , step S601 in FIG. 6 is executed. In step S601, the storage unit 131 is read. In step S603, it is judged whether the number of damaged data blocks is zero. In detail, the damage information of the storage unit 131 includes not only the location of the damaged data block but also the number of the damaged data block. When it is confirmed that the number of damaged data blocks is not zero, step S605 is executed. In step S605, repairing a damaged data block includes copying a data block corresponding to the damaged data block and replacing the damaged data block with the copied data block. Then in step S609, the number of damaged data blocks is reduced by one and the updated number of damaged data blocks is recorded in the storage unit 131, and then returns to step S601.

For example, when it is confirmed that the two first data blocks A1 and A5 in the first system data A are damaged by reading the storage unit 131, first copy the second data block B1 in the second system data B and copy the copied The second data block B1 replaces the first data block A1, and then the number of damaged data blocks recorded in the storage unit 131 is reduced by one. Next, copy the second data block B5 in the second system data B and replace the first data block A5 with the copied second data block B5, and then decrease the number of damaged data blocks recorded in the storage unit 131 by one again.

When it is confirmed that the number of damaged data blocks is zero, step S607 is executed. In step S607, the data restoration mechanism is completed. After the data recovery mechanism is completed, continue to step S315 in FIG. 3 .

The data restoration mechanism in FIG. 6 can be executed by the data processing system 1 in FIG. 1 . In detail, steps S601 - S609 are executed by the processor 11 of the data processing system 1 . However, the data restoration mechanism in FIG. 6 can also be executed by other data processing systems, and is not limited to be executed by the data processing system 1 in FIG. 1 .

FIG. 7 is a flowchart of the switching mechanism in FIG. 3 . Referring to FIG. 3 and FIG. 5 together, after step S315 (determined as “Yes”) and step S505, step S701 of FIG. 7 is then executed. In step S701, the storage unit 131 is read. Specifically, the state of the first system data A in use and the state of the second system data B not in use will be recorded in the storage unit 131, and by reading the storage unit 131, the first system data A and the The status of the second system profile B. In step S703, it is determined whether the second system profile B corresponding to the running first system profile A is complete. If it is confirmed that the second system data B is complete, step S705 is executed. In step S705, update the system usage status information in the storage unit 131, and then return to step S401 in FIG. 4 . In detail, in addition to recording the damaged data block information, the storage unit 131 also records system usage status information. For example, when the system usage status information record is the first system data A, it means that the system data currently running on the terminal device 1 is the first system data A. Conversely, when the system usage status information is recorded as the second system data B, it means that the system data currently running on the terminal device 1 is the second system data B. If it is confirmed that the second system data B is not complete, step S707 is executed. In step S707, the switching mechanism is exited. For example, if the first system data A is running system data, it is detected whether each second data block of the second system data B is damaged. When it is confirmed that each second data block of the second system data B is not damaged, it means that the second system data B is complete and can replace the running first system data A, and the second system data B is complete information record in the storage unit 131, and change the system usage state information recorded in the storage unit 131 from the first system data A to the second system data B. Then restart the terminal device 1. After the terminal device 1 is restarted, the system usage status information in the storage unit 131 is read, and the second system data B is selected as the loading target according to the system usage status information. Conversely, when any second data block in the second system data B is detected to be damaged, it means that the second system data B is not complete and cannot replace the running first system data A, so the switching mechanism is exited and the first system data is still maintained. A system data A is used as the system data in use.

The switching mechanism in FIG. 7 can be implemented by the data processing system 1 in FIG. 1 . In detail, steps S701 - S707 are executed by the processor 11 of the data processing system 1 . However, the switching mechanism in FIG. 7 can also be implemented by other data processing systems, and is not limited to be implemented by the data processing system 1 in FIG. 1 .

One of the beneficial effects of the present invention is that, through the data processing system of the terminal device and the data processing method of the terminal device provided by the present invention, the position of the damaged data block can be detected accurately and quickly, reducing unnecessary erasure and saving Repair time. Furthermore, since the states of the first system data and the second system data are detected during both the start-up phase and the running phase, damage points can be detected in real time, and the time for abnormal operation can be reduced. The data recovery mechanism provides power-off protection, supports power-off continuous recovery, and prolongs the service life of the terminal device. When the system data in use of the terminal device is abnormal and another unused system data is confirmed to be complete, the abnormal system data in use can be switched to the unused complete system data. In this way, the lifetime of the system data in the memory is extended. Furthermore, when the life of the memory reaches the limit and cannot be repaired, and the corresponding data blocks of the first system data and the second system data are damaged at the same time, the loading mechanism in the startup phase of the present invention can still ensure the terminal device Normal startup and operation, the life of terminal equipment normal operation has been improved again.
