Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a data processing method according to an embodiment of the present invention, where the embodiment is applicable to a case where a data storage is used to store data to be stored and a storage address and a data check code corresponding to the data to be stored simultaneously, and the method may be executed by a data processing apparatus, which may be implemented by software and/or hardware, and may be generally integrated in a computer device and used in cooperation with the data storage for storing data. Accordingly, as shown in fig. 1, the method comprises the following operations:
and S110, acquiring data to be stored.
The data to be stored may be data that needs to be stored in the data storage.
In the embodiment of the present invention, after obtaining the data storage instruction, the computer device may obtain the data to be stored. Optionally, the data to be stored may be data in a binary format or other formats, as long as the data can be stored in the data storage, and the embodiment of the present invention does not limit the data type of the data to be stored.
And S120, determining the storage address of the data to be stored.
The storage address may be an address in the data storage where data to be stored is stored.
Correspondingly, after the data to be stored is acquired, before the data to be stored is stored in the data memory, the storage address of the data to be stored needs to be determined first, so that the data to be stored is stored in the storage address of the data memory.
And S130, calculating a data check code according to the data to be stored and the storage address.
The data check code can be used for checking the data to be stored so as to confirm the correctness of the data to be stored.
In order to ensure that the data to be stored can be correctly stored in the data memory, the embodiment of the invention can store the data to be stored in a data redundancy mode. Specifically, a data check code corresponding to the data to be stored may be calculated according to the data to be stored and the storage address, so as to confirm the correctness of the data to be stored in the data storage through the data check code.
Optionally, a check code generation algorithm may be used to generate a data check code according to data formed by splicing the storage address and the data to be stored. The Check code generation algorithm may include, but is not limited to, a Cyclic Redundancy Check (CRC) algorithm or a Longitudinal Redundancy Check (LRC) algorithm, as long as a data Check code can be generated according to a storage address and data to be stored, and the specific algorithm type of the Check code generation algorithm is not limited in the embodiment of the present invention.
S140, storing the data to be stored, the storage address and the data check code into a data memory.
Correspondingly, after the data check code corresponding to the data to be stored is obtained, the computer equipment can store the data to be stored, the storage address and the data check code to the data storage device together. And after the data to be stored is stored in the data memory, the data to be stored is the stored data in the data memory.
Optionally, in order to facilitate reading the stored data, the computer device may control to store the data to be stored, the storage address, and the data check code in the data storage according to a certain rule. For example, the storage may be performed according to the sequence of the storage address, the data to be stored, and the data check code, which is not limited in this embodiment of the present invention.
In an optional embodiment of the invention, the data storage adopts a data storage unit to store data; the data storage unit may include an address storage subunit, a valid data storage subunit, and a check code storage subunit; the storing the data to be stored, the storage address, and the data check code into a data storage may include: storing the storage address to the address storage subunit; storing the data to be stored to the effective data storage subunit; and storing the data check code to the check code storage subunit.
The data storage unit may be a storage unit storing data to be stored. The address storage subunit may be configured to store a storage address of the data to be stored, the valid data storage subunit may be configured to store the data to be stored, and the check code storage subunit may be configured to store a data check code.
Specifically, the storage address may be stored in an address storage subunit of a certain data storage unit in the data storage, the data to be stored may be stored in an effective data storage subunit of the data storage unit, and the data check code may be stored in a check code storage subunit of the data storage unit. It is understood that one data to be stored corresponds to one storage address and one data check code. Accordingly, one data to be stored can be stored using one data storage unit. It should be noted that the memory spaces occupied by the address storage subunit, the valid data storage subunit, and the check code storage subunit may be the same or different, and specifically need to be determined according to the storage type of the data storage, which is not limited in the embodiment of the present invention.
In an alternative embodiment of the present invention, the data memory may include an EEPROM, and the address storage subunit may include two byte storage units; the data storage subunit may include four byte storage units; the check code storage subunit may include two byte storage units.
EEPROM can be repeatedly erased and written, and is well suited to storing some parameters. Typically, EEPROMs are 8byte type memories with data ranges of 0-0 xff. Conventional EEPROMs typically store only valid memory data, i.e., every 8 bytes of data storage cells are used to store data. The data storage mode is single, and the accuracy of the stored data is ensured singly. There are important situations in which parameter loading is erroneous due to an error in the stored parameters of the EEPROM, for example, when data is not successfully written into the EEPROM or the EEPROM stores erroneous data due to interference with communication timing, which may have serious consequences.
To this end, embodiments of the present invention improve the data storage format of the EEPROM in order to include the reliability of data storage in the EEPROM. Fig. 2 is a schematic diagram illustrating an effect of an EEPROM data storage format according to an embodiment of the present invention, and in a specific example, as shown in fig. 2, one data storage unit of the EEPROM may include 8 bytes. Wherein, the address storage subunit of one data storage unit may include two Byte storage units, such as Byte0 and Byte1, for storing two parts of the contents of the storage address, such as address a part and address b part; the data storage sub-unit may include four Byte storage units, such as Byte2-Byte5, for storing four parts of the data to be stored, such as a valid data a part, a valid data b part, a valid data c part, and a valid data d part; the check code storage sub-unit may include two Byte storage units, e.g., Byte6 and Byte7, for storing two parts of the data check code, e.g., a data check code a part and a data check code b part.
That is, one to-be-stored data needs to store one storage address and one data check code correspondingly. When the data check code is used for reading data from the data memory, the check data serving as a reference is compared with the data check code calculated in real time according to the read data for checking. If the comparison and verification results of the data verification codes are consistent, the data storage is correct, and correct stored data can be returned; otherwise, indicating that the data is stored incorrectly, an error message may be returned, such as a data read failure message.
In an optional embodiment of the present invention, after the storing the data to be stored, the storage address, and the data check code in the data storage, the method may further include: reading target stored data in the data memory; comparing and checking the target stored data and the data to be stored; and under the condition that the target stored data and the to-be-stored data are determined to be inconsistent, returning to execute the operation of storing the to-be-stored data, the storage address and the data check code into a data memory until the target stored data and the to-be-stored data are determined to be consistent.
The target stored data may be stored data corresponding to data to be stored and stored in the data storage.
In order to avoid data storage errors caused by abnormal conditions in the data storage process, after the data to be stored, the storage address and the data check code are stored in the data storage, the target stored data which is just written into the data storage can be read, and the target stored data and the original data to be stored are compared and checked. If the target stored data and the data to be stored are determined to be inconsistent in verification result, which indicates that the data storage fails, the operation of storing the data to be stored, the storage address and the data verification code in the data memory can be returned to be executed again until the target stored data and the data to be stored are determined to be consistent in verification result. And if the verification result of the target stored data and the data to be stored is determined to be consistent, indicating that the data storage is successful, successfully writing the data into the data memory.
According to the embodiment of the invention, after the data to be stored is obtained, the storage address of the data to be stored is determined, and the data check code is calculated according to the data to be stored and the storage address, so that the data to be stored, the storage address and the data check code are stored in the data storage together, the data storage ensures the reliability of data storage by using a data redundancy mode, the problem of low reliability of data storage caused by a single data storage mode of the conventional data storage can be solved, the accuracy of data storage in the data storage is improved, and the reliability of the data storage is improved.
Example two
Fig. 3 is a flowchart of a data processing method according to a second embodiment of the present invention, where this embodiment is applicable to a case where stored data of a data storage is read by using a data check code, and the method may be executed by a data processing apparatus, which may be implemented by software and/or hardware, and may be generally integrated in a computer device and used in cooperation with the data storage for storing data. Accordingly, as shown in fig. 3, the method includes the following operations:
s210, acquiring a data reading address of target reading data.
Wherein the target read data may be stored data that needs to be read from the data storage. The data read address may be an address at which target read data is stored in the data memory.
In the embodiment of the present invention, after the computer device obtains the reading instruction of the target reading data, the data reading address of the target reading data may be obtained according to the reading instruction of the target reading data.
S220, reading the data memory according to the data reading address to obtain target storage data, a target storage address and a target data check code.
The target storage data may be storage data matched with the data reading address, the target storage address may be a storage address of the target storage data, and the target data check code may be a data check code corresponding to the target storage data.
Correspondingly, the computer equipment can read the data memory according to the data reading address to obtain target storage data, a target storage address and a target data check code which are matched with the data reading address. It will be appreciated that the data read address and the target memory address are the same.
In an optional embodiment of the present invention, the data storage may comprise an EEPROM, the data storage stores data using data storage units; the data storage unit may include an address storage subunit, a valid data storage subunit, and a check code storage subunit; wherein: the address storage subunit is used for storing the target storage address; the data storage subunit is used for storing the target storage data; the check code storage subunit is used for storing the target data check code.
Optionally, the address storage subunit may include two byte storage units; the data storage subunit may include four byte storage units; the check code storage subunit may include two byte storage units.
Alternatively, if the data storage is of the EEPROM type, the computer device may read 8 bytes of data in one data storage unit in the EEPROM according to the data read address. In the 8 bytes of data in the data storage unit, the 2 bytes of data corresponding to the address storage subunit form a target storage address, and the target storage address is the same as the data reading address; the data of 4 bytes corresponding to the data storage subunit forms target storage data, and the data of 2 bytes corresponding to the check code storage subunit forms a target data check code.
And S230, calculating a temporary data check code according to the target storage address and the target storage data.
The temporary data check code may be a data check code calculated in real time according to the target storage address and the target storage data.
Accordingly, after obtaining the target storage data, the target storage address and the target data check code, the computer device may calculate the temporary data check code according to the target storage data and the target storage address. Optionally, a temporary data check code may be generated according to data formed by splicing the target storage address and the target storage data by using a check code generation algorithm. The check code generation algorithm may include, but is not limited to, a CRC or LRC algorithm, for example, as long as the temporary data check code can be generated according to the target storage address and the target storage data, and the specific algorithm type of the check code generation algorithm is not limited in the embodiment of the present invention. However, it should be noted that the check code generation algorithm adopted by the computer device when writing the data to be stored into the data storage needs to be consistent with the check code generation algorithm adopted for calculating the temporary data check code. Meanwhile, the generation rule of the check code adopted by the computer device when writing the data to be stored into the data memory also needs to be consistent with the generation rule of the check code adopted by calculating the temporary data check code.
S240, under the condition that the temporary data check code is consistent with the target data check code, returning the target storage data as the target reading data.
Specifically, after the computer device calculates the temporary data check code, consistency comparison and verification can be performed on the temporary data check code and the target data check code. If the temporary data check code is consistent with the target data check code and indicates that the target storage data is correct, the target storage data can be used as target reading data to be returned. If the temporary data check code is determined to be inconsistent with the target data check code, indicating that the target stored data is wrong, an error message may be returned, such as a data read failure message.
According to the embodiment of the invention, after the reading instruction of the target reading data is obtained, the data reading address of the target reading data is obtained, the data memory is read according to the data reading address, the target storage data, the target storage address and the target data check code are obtained, meanwhile, the temporary data check code is calculated according to the target storage address and the target storage data, and then the temporary data check code and the target data check code are compared and checked. And if the temporary data check code is consistent with the target data check code, determining that the target storage data is correct, and returning the target storage data as target reading data. The technical scheme can solve the problem of low reliability of data storage caused by single data storage mode of the existing data storage, thereby improving the accuracy of data storage in the data storage and further improving the reliability of the data storage.
It should be noted that any permutation and combination between the technical features in the above embodiments also belong to the scope of the present invention.
