Abstract

The invention provides a variable processing method and device in an A2L file, and a storage medium. The method reads an A2L file into an internal storage by lines and obtains partial content of the A2L file as to-be-processed information, so that variables which needs to be processed can be rapidly and accurately found by only searching in the to-be-processed information, the variables that do not exist in the A2L file can be avoided from being processed later, and therefore, processing efficiency can be enhanced, and the total time consuming of processing can be reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a variable processing method, device and storage medium in an A2L file. Background technique [0002] At present, in the field of development of automotive electronic controllers, the international general V-shaped development mode is applied. Set the MATLAB control model according to the control requirements, and use the MATLAB code to automatically generate C code and A2L files. The parameter address of the variable in the A2L file is a virtual address, which needs to be replaced by the physical address of the variable in the linker map file (Linker MAP File, MAP) generated by compilation before it can be used. [0003] Usually, it is necessary to first traverse the correspondence between all variables and their corresponding physical addresses in the MAP file, and then search through the A2L file for each variable, find the variable in the A2L file and perform address...
