Learning objectives: 

  Familiarity with formal languages and their models. Grasp of compiler construction. 
Description: 

  This course discusses formal languages and their models. Based on these models, it explains the construction of compilers. The lectures are organized as follows: (I) Basic notions: formal languages and their models, grammars, automata; compilers. (II) Regular languages and lexical analysis: regular languages and expressions, finite automata, lexical analyzer; symbol table. (III) Contextfree languages and syntax analysis: contextfree grammars, pushdown automata, deterministic topdown syntax analysis (recursive descent), the essence of deterministic bottomup syntax analysis. (IV) Semantic analysis and code generation: intermediate code generation, optimization, code generation. 
Knowledge and skills required for the course: 

  Discrete mathematics. 
Learning outcomes and competences: 

  Fundamental familiarity with the theory of formal languages. Ability of a compiler construction. 
Syllabus of lectures: 


 Basics of formal languages: alphabet, strings, languages.
 Introduction to compiler design: structure of a compiler.
 Regular languages and their models: regular expressions, finite automata.
 Variants of finite automata.
 Lexical analysis: lexical analyzer, symbol table.
 Contextfree languages and their models: contextfree grammars, pushdown automata.
 Pushdown automata and general parsing.
 Deterministic topdown syntax analysis: recursive descent.
 Deterministic bottomup syntax analysis: simple precedence analysis.
 Chomsky hierarchy and the corresponding models. Remarks and summary.
