Method and system for decoding of original code flow

Abstract

The invention relates to a method and system for decoding of an original code flow. The method comprises the steps that field attribute information which uses a decoding base at present is written into a configuration document; the configuration document is read, and the field attribute information is loaded to memory; an original code flow of a user side is received; fields of the original code flow are traversed and analyzed successively according to the field attribute information; and analysis results are output in a formatted manner according to user demands. According to the invention, code flow data structure information is completely decoupled with a program; when a field value needs to be acquired, only simple modification of the configuration document is necessary, so that a freshman can rapidly join a project, and code rows will not linearly increase with the quantity of fields. Forcible data structure conversion is not needed; the original code flow is accessed by a pointer according to bytes (unit) and accessed successively according to offset amounts; during frequent decoding, the decoding can be accelerated effectively; and the code rows are stable, and will not be modified or changed obviously according to demands.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an original code stream decoding method. Background technique [0002] Processing the original code stream is a very important link in the field of communication. The process of parsing the original code stream is relatively cumbersome. For large-scale programs to decode the original code stream, not only accurate decoding is required, but also real-time performance is required. Of course, the fewer lines of code, the better. In some existing decoding methods, the original code stream is first forcibly converted into the current code stream data structure, and then the corresponding fields are extracted according to the field alignment. For example, to extract the field "unsigned short subframeAssignment" from the original code stream unsigned char*msg, the relevant decoding library data is as follows (the actual situation is more complicated than this structure), ...

Problems solved by technology

Although the above decoding method achieves correct decoding, its performance is not high in frequent decoding and high real-time requirements

And as the field value information is added, deleted, and updated, the source code needs to be updated. The acquisition of each field value will involve the change of the same order of magnitude of code, so: the code line will be huge, messy, difficult to maintain, and not conducive to novices Quickly join the project
