OBJECTIVE: To study the general features of Compilers.
1. LEXICAL ANALYSIS 
Introduction on the phase of the compiler — Lexical Analysis, Regular Expression, Nondeterministic Automata, Deterministic Automata equivalent to NFA’s . Minimizing the states of DFA, Implementation of Lexical Analyzer
2. SYNTAX ANALYSIS 
Syntax Analysis — Topdown Parsing Concepts ,Recursive Descent Parsing, Predictive Parsers, Nonrecursive Predictive Parsing — Bottom Up Parsing, Handle pruning, Shift reduce parsing — Operator Precedence Parsing — Error recovery in Parsing, LR Parsers, Parser Generators — YACC
3. INTERMEDIATE CODE GENERATION 
Syntax directed Definitions, Construction of Syntax trees — Top down Translation, Bottom up Evaluation of Inherited Attributes, Recursive Evaluators, Assigning Space at Compiler Construction time — Type checking — Overloading of functions and operators, polymorphic function.
4. STORAGE ORGANIZATION 
Storage Organization, Storage Allocation strategies, Parameter Passing, Symbol tables, Dynamic Storage Allocation, Intermediate Languages - Representation of Declarations, Assignment statement, Boolean Expression, Back Patching, Procedure calls.
5. CODE GENERATION AND OPTIMIZATION 
Design of the code generators ,Runtime storage management, Basic blocks and Flow graphs, Register Allocation and Assignment , DAG representation of Basic blocks, Peephole optimization, Code optimization — The principle Sources of Optimization, Optimization of basic blocks, Global data flow Analysis, Loop optimizations.
