Catalog Description


Prerequisite: CSCI 325 and 422. Offered in fall, spring, and summer.

Principles and practices in the design of compilers. Lexical analysis. Syntax analysis, top-down and bottom-up parsing. Syntax-directed translation and syntax trees. Declarations, types, and symbol management. Run-time environments, storage organization, parameter passing, dynamic storage allocation. Intermediate languages and intermediate code generation. Code generation and optimization. Project: students construct a simple compiler that generates unoptimized code.



Kenneth Louden, Compiler Construction: Principles and Practice, PWS publishing company, 1997.


To present a practical approach to the subject of compiler construction.

To cover the components of a compiler and how they fit together.

To automate the generation of compiler components using Lex and Yacc.
