Learning objectives:
  Familiarity with formal languages and their models. Grasp of compiler construction.
  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) Context-free languages and syntax analysis: context-free grammars, pushdown automata, deterministic top-down syntax analysis (recursive descent), the essence of deterministic bottom-up 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.
  • Context-free languages and their models: context-free grammars, pushdown automata.
  • Pushdown automata and general parsing.
  • Deterministic top-down syntax analysis: recursive descent.
  • Deterministic bottom-up syntax analysis: simple precedence analysis.
  • Chomsky hierarchy and the corresponding models. Remarks and summary.
