All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms to which the present invention relates will be explained first:
A2L file: the A2L file is a file describing internal variables of an Electronic Control Unit (ECU) and includes two parts, namely a measurement variable and a calibration variable, and the A2L file corresponds to a program one by one. Through the A2L file, the calibration tool identifies information such as variable names, variable addresses, variable lengths and the like in the program.
And (3) MAP file: the embedded software is processed by the compiler to generate a description file which stores information such as variable names and corresponding addresses.
A dictionary: a variable type stored in the form of a key-value pair in a scripting language.
Fig. 1 is a flowchart of a method for processing variables in an A2L file according to an embodiment of the present application. The execution subject of the method can be a processing device of the variable in the A2L file. As shown in fig. 1, a method for processing variables in an A2L file provided in an embodiment of the present application includes:
s101, reading the A2L file into a memory according to lines, and acquiring information to be processed.
The number of rows of the information to be processed is N, and N is a positive integer and is less than the total number of rows of the A2L file.
And S102, if the variable is found in the information to be processed, acquiring the name of the variable.
Specifically, the processing device for the variables in the A2L file reads the character strings in the A2L file line by line into the memory, uses the N lines of read character strings as the information to be processed, and searches the variables in the information to be processed. In general, in the A2L file, the storage form of the variable has a prescribed format, and the variable can be searched in the information to be processed according to the prescribed format, and after the variable is searched, the name of the variable is extracted from the variable.
The size of N is not limited in this embodiment, and the value of N may be determined according to a format specified in the A2L file with respect to the variable storage form.
According to the method for processing the variables in the A2L file, the A2L file is read into the memory according to the lines, part of the content of the A2L file is obtained as the information to be processed, the variables needing to be processed can be quickly and accurately found by only searching the variables in the information to be processed, the follow-up processing aiming at the variables which do not exist in the A2L file is avoided, the processing efficiency is improved, and the total processing time is reduced.
Fig. 2 is a flowchart of a method for processing variables in the A2L file according to the second embodiment of the present application. The present embodiment provides an implementation manner of S101 on the basis of the embodiment shown in fig. 1. As shown in fig. 2, in S101, reading the A2L file into the memory by rows to obtain the information to be processed may include:
s201, reading a K-th line of character strings in the A2L file into a memory; k is a positive integer.
S202, judging whether the initial character string of the K-th row of character strings is the first character string. Wherein the first string is used to begin defining variables.
If the initial string of the K-th string is the first string, then S203 is executed. If the initial string of the kth string is not the first string, S207 is executed.
S203, reading the K +1 th line character string in the A2L file into the memory.
After that, S204 is executed.
S204, judging whether the initial character string of the K +1 th row of character strings is a second character string. Wherein the second string is used to end the defined variable.
If the initial string of the K +1 th string is the second string, S205 is executed. If the starting string of the K +1 th string is not the second string, S206 is executed.
S205, obtaining information to be processed, wherein the information to be processed comprises the K-th line character string to the K + 1-th line character string.
S206, taking K +1 as a new K, and returning to execute S203.
Specifically, in the A2L file, the storage form of a variable generally has a prescribed format. For example, the storage of variables may include multiple lines of strings. In a plurality of lines of strings, with a first string as the beginning of the variable description and a second string as the end of the variable description, the virtual address of the variable may be located in the string between the first string and the second string. Therefore, the A2L file can be read into the memory by line, and whether the current read line is the beginning of the variable description is determined according to whether the initial character string of the current read line character string is the first character string, and whether the current read line is the end of the variable description is determined according to whether the initial character string of the current read line character string is the second character string. Further, the complete A2L description string of one variable is determined, that is, the information to be processed is acquired.
In the embodiment, by using the specific format of the A2L file and taking the complete A2L description character string of one variable as the basic unit for searching the variable, the search range of the variable is narrowed, and the speed of determining the variable in the A2L file is improved.
This is illustrated by way of example.
In the A2L file, the variables may include calibration variables and measurement variables. Optionally, in one example, one stored form of the calibration variables is as follows:
in this example, the calibration variable may be stored beginning with the string "begin CHARACTERISTIC" and ending with the string "end CHARACTERISTIC", with a string between the string "begin CHARACTERISTIC" and the string "end CHARACTERISTIC" that has variable names, variable addresses, variable lengths, data types, minimum values, and maximum values describing the calibration variable. In this example, the first string may be "begin" and the second string may be "end". A character string between the first character string "begin" and the second character string "end" may be determined as the information to be processed.
Alternatively, in another example, in one stored form of the measured variable, the measured variable may begin with the string "begin MEASUREMENT" and end with the string "end MEASUREMENT", where the string "begin MEASUREMENT" and the string "end MEASUREMENT" have a string describing the variable name, variable address, variable length, calculation formula, precision, minimum value, and maximum value of the measured variable. In this example, the first string may be "begin" and the second string may be "end". A character string between the first character string "begin" and the second character string "end" may be determined as the information to be processed.
The first character string and the second character string are merely examples, and the first character string and the second character string are not limited.
The current behavior K is taken as an example below. Firstly, reading the K-th string in the A2L file into a memory, and judging whether the initial string of the K-th string is the first string. And if the initial character string of the K-th row of character strings is judged to be the first character string, determining that the K-th row of character strings is the start of variable description, continuously reading the K + 1-th row of character strings in the A2L file into the memory, and judging whether the initial character string of the K + 1-th row of character strings is the second character string. If the initial character string of the (K + 1) th row of character strings is the second character string, determining that the (K + 1) th row of character strings is the end of variable description, and further taking the (K) th row of character strings to the (K + 1) th row of character strings as complete A2L description character strings representing a variable, namely taking the (K) th row of character strings to the (K + 1) th row of character strings as information to be processed. And if the initial character string of the (K + 1) th row of character strings is not the second character string, continuously reading the (K + 2) th row of character strings, and judging whether the initial character string of the (K + 2) th row of character strings is the second character string. Similarly, if the initial character string of the (K + 2) th row of character strings is the second character string, determining that the (K + 2) th row of character strings is the end of the variable description, and taking the (K + 2) th row of character strings to the (K + 2) th row of character strings as the information to be processed, otherwise, continuously reading the next character string until the character string of which the initial character string is the second character string is read. For example, if the starting string of the K + n-th string is the second string, determining that the K + n-th string is the end of the variable description, and taking the K-th string to the K + n-th string as the information to be processed, where n is an integer greater than or equal to 1.
Optionally, in S202, if the starting string of the kth string is not the first string, S207 is executed.
And S207, writing the K-th line character string into a new A2L file.
Specifically, when the A2L file is read into the memory by line, if the initial character string of the kth line character string is determined not to be the first character string, it may be determined that the kth line character string is not the start of the variable description, and then it is not necessary to process a certain character string in the kth line character string. Therefore, the K line string can be written directly into the new A2L file. By directly writing some character strings which do not need further processing into a new A2L file, the search range of the character strings with specific identifications can be reduced, and the search speed of the character strings with specific variables is improved.
Fig. 3 is a flowchart of a method for processing variables in the A2L file according to a third embodiment of the present application. The present embodiment provides an implementation manner of S102 on the basis of the embodiment shown in fig. 1. As shown in fig. 3, in S102, if the variable is found in the information to be processed, acquiring the name of the variable may include:
s301, matching a preset regular expression with the information to be processed, and judging whether the information to be processed comprises a variable or not; the preset regular expression comprises a preset identifier, and the preset identifier is used for identifying a variable.
S302, if the information to be processed comprises the variable, acquiring the name of the variable according to the preset identifier.
Specifically, in the A2L file, the storage form of a variable usually has a prescribed format, for example, the variable name, the variable type, and the variable address have a prescribed representation form. Wherein the variable address can be identified by a character string with a specific identification, for example. Therefore, the preset regular expression may be constructed according to the representation form of the variable address in the A2L file, so that the preset regular expression includes a preset identifier for identifying the variable address. And matching the preset regular expression with the acquired information to be processed, and judging whether the information to be processed has a character string with a preset identifier. If a character string with a preset identifier is found in the information to be processed, the variable name can be extracted from the character string.
In this embodiment, specific content of the preset identifier is not limited. The preset identifier may be determined according to a defined format of the variable address in the A2L file.
In the following, the expression form of the variable address in the A2L file is exemplified by the string "@ mem @ where" @ "represents the name of the variable. The preset regular expression can be constructed according to the character string "@ mem @" so that the preset regular expression has a preset identifier representing "@ mem @ @". And searching the information to be processed by using a preset regular expression. After finding the string with the preset identifier, extracting the variable name from the string. For example, the character string "@ mem @ test _ var @ is found in the information to be processed, and then the variable name" test _ var "may be extracted from the character string.
In this embodiment, by using a specified format for storing variables in the A2L file, a regular expression is constructed as needed to search for the variables, and the variables that need to be processed can be quickly and accurately located.
Fig. 4 is a flowchart of a method for processing variables in the A2L file according to the fourth embodiment of the present application. The method for processing the variables in the A2L file provided in this embodiment may further include:
s401, according to the corresponding relation between the variable and the physical address stored in the memory, obtaining the physical address corresponding to the variable.
S402, replacing the address of the variable according to the physical address corresponding to the variable, and writing the information to be processed after address replacement into a new A2L file.
Specifically, the correspondence between the variable name and the physical address is stored in the memory in advance, and after the variable name is acquired in S102, the physical address corresponding to the variable may be acquired according to the variable name. After the physical address corresponding to the variable is obtained, the physical address is adopted to replace the virtual address corresponding to the variable in the information to be processed, and the conversion from the virtual address of the variable in the information to be processed to the physical address is realized. And then writing the information to be processed after address replacement into a new A2L file.
In this embodiment, the obtaining manner of the corresponding relationship between the variable and the physical address stored in the memory is not limited. For example, all variables and their corresponding physical addresses may be traversed in the MAP file, and the found variables and corresponding physical addresses are stored in the memory as a dictionary in a one-to-one key-value pair form. For example, all variables traversed in the MAP file and their corresponding physical addresses may be stored in the memory with the variable name as a key and their corresponding physical addresses as a value.
According to the processing method for the variables in the A2L file, provided by the embodiment of the application, the main body of address replacement is converted from the characters of the whole A2L file into the A2L description character strings of a single variable, so that the unit time of the address replacement operation is reduced, meanwhile, the replacement of all addresses can be completed only by traversing the A2L file once, and the processing speed of the address replacement of the A2L file is improved. Experiments show that for a large A2L file, the processing speed of the A2L file address replacement can be improved by 6-8 times by adopting the processing method of the variables in the A2L file provided by the embodiment of the application.
