Course Description
Compiler Design introduces the principles and techniques involved in designing translators that convert high-level programming languages into machine-level or intermediate code. A compiler performs several well-defined phases to analyze source programs, detect errors, construct internal representations, and generate efficient target code.
The course covers lexical analysis, syntax analysis, parsing techniques, semantic processing, syntax-directed translation, intermediate code generation, memory organization, and code optimization. It also introduces compiler construction tools such as lexical analyzer generators and YACC.
