It is dominant in the current flat panel display market. LCD monitors are widely used in various types of electronics. Devices, such as mobile phones, tablets, etc.
液晶显示器的驱动电路中，时序控制器是非常重要的部件。在时序控制器中，如图1所示，采用时序控制芯片(TCON)1外接EEPROM或者FLASH存储器2来存储数据已经演变为一种固定架构，并且需要在存储器2中规划出特定区域用于数据存储，如图1中数据存储区2a。时序控制芯片1能够通过数据总线3对存储器2进行读写操作，并要求能够实现写入后即能保存功能。当需要进行更新时，时序控制芯片1会读出当前数据存储区2a中的内容，先擦除，然后再写入新的内容，完成更新的过程。在对存储数据进行修改时，必须在整个写入过程中保持工作电压的稳定，如果在数据更新的过程中发生意外掉电，有可能出现之前存储的数据已被擦除但是新的数据未被写入的情况，导致存储器中的数据丢失而失效，相应的***(例如驱动电路)无法正常工作。因此，针对在数据更新的过程中发生意外掉电时，如何防止数据失效是一个需要非常重视的问题。In the drive circuit of the liquid crystal display, the timing controller is a very important component. In the timing controller, as shown in FIG. 1, the use of the timing control chip (TCON) 1 external EEPROM or FLASH memory 2 to store data has evolved into a fixed architecture, and a specific area needs to be planned in the memory 2 for data. Storage, as in the data storage area 2a in FIG. The timing control chip 1 can read and write the memory 2 through the data bus 3, and is required to be able to save the function after writing. When an update is required, the timing control chip 1 reads out the contents of the current data storage area 2a, erases it first, and then writes the new content to complete the update process. When modifying the stored data, the operating voltage must be kept stable throughout the writing process. If an unexpected power failure occurs during the data update, it may happen that the previously stored data has been erased but the new data is not. In the case of writing, the data in the memory is lost and fails, and the corresponding system (such as the driving circuit) does not work properly. Therefore, how to prevent data failure is an issue that needs to be taken seriously when accidental power failure occurs during data update.

下面详细介绍如上所提供的数据存储装置防止数据失效的方法。如图3的
流程图，该方法包括：The method of preventing data failure by the data storage device as provided above is described in detail below. As shown in Figure 3
Flow chart, the method includes:
S1、***上电时写入数据的步骤：将相同的数据依次写入可擦写存储器的第一存储区域和第二存储区域。S1: Step of writing data when the system is powered on: the same data is sequentially written into the first storage area and the second storage area of the rewritable memory.
S2、重新上电对数据进行校验的步骤：依次读取存储于第一存储区域和第二存储区域中的数据并进行校验，根据校验结果选择有效数据。其中，数据校验的结果包括以下几种情形：S2. Step of verifying data by re-powering: sequentially reading data stored in the first storage area and the second storage area and performing verification, and selecting valid data according to the verification result. Among them, the results of data verification include the following situations:
(A)、若第一存储区域的数据校验成功，第二存储区域的数据也校验成功，则选择第一存储区域的数据或第二存储区域的数据作为有效数据。(A). If the data verification of the first storage area is successful and the data of the second storage area is also verified successfully, the data of the first storage area or the data of the second storage area is selected as the valid data.
(B)、若第一存储区域的数据校验成功，第二存储区域的数据校验失败，则选择第一存储区域的数据作为有效数据。(B) If the data verification of the first storage area is successful and the data verification of the second storage area fails, the data of the first storage area is selected as the valid data.
(C)、若第一存储区域的数据校验失败，第二存储区域的数据校验成功，则选择第二存储区域的数据作为有效数据。(C) If the data verification of the first storage area fails and the data verification of the second storage area is successful, the data of the second storage area is selected as the valid data.
针对在数据更新的过程中发生意外掉电，存在以下几种可能性：There are several possibilities for accidental power loss during data update:
(1)、先后对第一存储区域和第二存储区域的数据更新完成后，***发生意外断电，此时第一存储区域和第二存储区域的数据是一致的，并且是更新之后的。该种情况对应于前述数据校验结果中的情形(A)，由于第一存储区域和第二存储区域的数据都是更新后并且有效地，因此可以任意选择第一存储区域的数据或第二存储区域的数据作为有效数据，都可以保证***能够正常工作，并确保工作的实时性。(1) After the data update of the first storage area and the second storage area is completed, the system unexpectedly loses power, and the data of the first storage area and the second storage area are consistent and updated. This case corresponds to the situation (A) in the foregoing data check result. Since the data of the first storage area and the second storage area are both updated and effective, the data of the first storage area or the second can be arbitrarily selected. The data in the storage area is used as valid data to ensure that the system works properly and ensures real-time work.
(2)、对第一存储区域的数据更新完成后，在未开始对第二存储区域的数据进行更新时，***发生意外断电，此时第一存储区域的数据是更新后且有效地，第二存储区域的数据是更新之前但也是有效的。该种情况对应于前述数据校验结果中的情形(A)，可以任意选择第一存储区域的数据或第二存储区域的数据作为有效数据。由于第二存储区域的数据是更新之前的，因此选择第二存储区域的数据作为有效数据可以保证***能够正常工作，但不具有实时性，并不是最优化的技术方案。因此，在前述的情形(A)中，还进一步校验第一存储区域的数据和第二存储区域的数据的一致性，若第一存储区域的数据与第二存储区域的数据不一致，则选择第一存储区域的数据作为有效数据。第一存储区域的数据是更新之后的，可以保证***能够正常工作，并确保工作的实时性。更进一步地，为了确保第一存储区域和第二存储区域的数据都是最新的，若第
一存储区域的数据与第二存储区域的数据不一致时，在选择第一存储区域的数据作为有效数据之后，以第一存储区域的数据作为参考，将相同的数据重新写入到第二存储区域。(2) After the data update of the first storage area is completed, when the data of the second storage area is not updated, the system unexpectedly loses power, and the data of the first storage area is updated and valid. The data of the second storage area is before the update but is also valid. This case corresponds to the case (A) in the aforementioned data check result, and the data of the first storage area or the data of the second storage area can be arbitrarily selected as the valid data. Since the data of the second storage area is before the update, selecting the data of the second storage area as the effective data can ensure that the system can work normally, but does not have real-time performance, and is not an optimized technical solution. Therefore, in the foregoing case (A), the consistency of the data of the first storage area and the data of the second storage area is further verified, and if the data of the first storage area is inconsistent with the data of the second storage area, then the selection is made. The data of the first storage area is taken as valid data. The data of the first storage area is updated, which ensures that the system can work normally and ensures the real-time work. Further, in order to ensure that the data of the first storage area and the second storage area are the latest, if the first
When the data of one storage area is inconsistent with the data of the second storage area, after the data of the first storage area is selected as the valid data, the same data is rewritten to the second storage area with the data of the first storage area as a reference. .
(3)、对第一存储区域的数据更新完成后，在对第二存储区域的数据进行更新时，***发生意外断电，此时第一存储区域的数据是更新后且有效地，第二存储区域的数据可能已经丢失并且无法恢复。该种情况对应于前述数据校验结果中的情形(B)，第一存储区域的数据是更新后并且有效地，选择第一存储区域的数据作为有效数据，可以保证***能够正常工作，并确保工作的实时性。更进一步地，为了防止下次掉电时第一存储区域和第二存储区域的数据同时失效，在选择第一存储区域的数据作为有效数据之后，以第一存储区域的数据作为参考，将相同的数据重新写入到第二存储区域。(3) After the data update of the first storage area is completed, when the data of the second storage area is updated, the system unexpectedly loses power, and the data of the first storage area is updated and effective, and second The data in the storage area may have been lost and cannot be recovered. This case corresponds to the situation (B) in the foregoing data verification result. The data of the first storage area is updated and effective, and the data of the first storage area is selected as the valid data, so that the system can work normally and ensure The real-time nature of the work. Further, in order to prevent data of the first storage area and the second storage area from simultaneously failing at the time of the next power failure, after selecting the data of the first storage area as the valid data, the data of the first storage area is used as a reference, and the same The data is rewritten to the second storage area.
(4)、在对第一存储区域的数据进行更新时，***发生意外断电，此时第一存储区域的数据可能已经丢失并且无法恢复；而第二存储区域的数据由于未开始更新，仍然得以保留上一阶段的数据。该种情况对应于前述数据校验结果中的情形(C)，虽然第二存储区域的数据是更新之前的，不具有实时性，但至少保证***能够正常工作。更进一步地，为了防止下次掉电时第一存储区域和第二存储区域的数据同时失效，在选择第二存储区域的数据作为有效数据之后，以第二存储区域的数据作为参考，将相同的数据重新写入到第一存储区域。(4) When the data of the first storage area is updated, the system unexpectedly loses power, and the data of the first storage area may have been lost and cannot be recovered; and the data of the second storage area is still not updated. It is possible to retain the data of the previous stage. This case corresponds to the situation (C) in the foregoing data check result. Although the data of the second storage area is before the update and does not have real-time performance, at least the system can be guaranteed to work normally. Further, in order to prevent data of the first storage area and the second storage area from failing simultaneously at the next power failure, after selecting the data of the second storage area as the valid data, the data of the second storage area is used as a reference, and the same The data is rewritten to the first storage area.
在本实施例中，所述数据校验模块11采用CRC数据校验算法对数据进行校验。CRC校验即循环冗余校验码(Cyclic Redundancy Check)，是数据通信领域中最常用的一种差错校验码。In this embodiment, the data verification module 11 performs verification on the data by using a CRC data verification algorithm. The CRC check is the Cyclic Redundancy Check, which is the most commonly used error check code in the field of data communication.
如上实施例提供的数据存储装置及其防止数据失效的方法，将存储器划分出第一存储区域和第二存储区域，并且第一存储区域和第二存储区域存储相同的数据，若更新过程中发生意外掉电，该装置也可以确保所存储的数据的有效性，保证包含该数据存储装置的***能够正常、稳定地运行。The data storage device provided by the above embodiment and the method for preventing data failure thereof, divide the memory into the first storage area and the second storage area, and the first storage area and the second storage area store the same data, if the update process occurs In case of accidental power failure, the device can also ensure the validity of the stored data, and ensure that the system including the data storage device can operate normally and stably.
