Abstract

The embodiment of the invention provides a coder decoder generating device and method. The method includes the steps that a character string of a description file of a data format class is analyzed into multiple word symbols; semantic analysis is carried out on the multiple word symbols according to a syntax rule, and a syntax tree is generated; nodes of the syntax tree are traversed, sub coder decoder units corresponding to the nodes are built, and the sub coder decoder units are strung to form a coder decoder object tree corresponding to the syntax tree, wherein each sub coder decoder unit comprises a coder decoder unit body of a combined type and a coder decoder unit body of a simple type, the coder decoder unit bodies of the combined type are located on branch nodes or root nodes of the coder decoder object tree, the coder decoder unit bodies of the simple type are located on leaf nodes of the coder decoder object tree, and coder decoder interfaces of the root nodes of the coder decoder object tree are coding and decoding inlets of a coder decoder.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a device and method for generating a codec. Background technique [0002] Abstract Syntax Notation One (ASN.1) is an international standard that describes a data format for representing, encoding, transmitting and decoding data. Anywhere information needs to be sent digitally, it can be based on ASN.1 to send information in various forms (audio, video, data, etc.). [0003] In the prior art, the ASN.1 codec is mainly implemented in the form of a plug-in. Specifically, first write the ASN.1 file, then use the corresponding code automatic generation tool to convert the ASN.1 file into a C or C++ or java source file, and finally compile the source file into a dynamic link library or jar package, the dynamic link Libraries or jar packages exist in the form of plug-ins and are called by applications. [0004] However, in the process of making a plug-in, it is ...
