80C51汇编语言词法分析器的设计与实现

Design and Implementation of a Lexer on 80C51 Assembler

以编译原理理论为基础,详细介绍了80C51汇编语言的词法分析器的设计与实现中几项关键技术:正则表达式,状态转换图,符号表,词法分析器和语法分析器的交互等,提出了80C51汇编语言词法分析器的设计方法,实现了词法分析器的设计.

Based on principles of compiler design,this paper makes a detailed description of the key techniques in the design and implementation of a 80C51 assembler,such as regular expression,transition diagram,symbol table,and the method of the communication between Lexer and Parser.It propses 80C51 assembler Lexer design methods,realizing the Lexer design.
