A New Approach of Complier Design in Context of Lexical Analyzer
Abstract
A compiler translates and/or compiles a program written in a suitable source language into an
equivalent target language through a number of stages. Starting with recognition of token
through target code generation provide a basis for communication interface between a user and
a processor in significant amount of time. A new approach GLAP model for design and time
complexity analysis of lexical analyser is proposed in this paper. In the model different steps
of tokenize (generation of tokens) through lexemes, and better input system implementation
have been introduced. Disk access and state machine driven Lex are also reflected in the model
towards its complete utility. The model also introduces generation of parser. Implementation
of symbol table and its interface using stack is another innovation of the model in acceptance
with both theoretically and in implementation widely.
