Course details

Formal Languages and Compilers (in English)

IFJe Acad. year 2022/2023 Winter semester 5 credits

Current academic year

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.

Syllabus - others, projects and individual work of students

The task is to implement a program which, given a composition of functions,transforms it to an equivalentmathematical expression. 

Progress assessment

  • Mid-term exam - 20 points.
  • Project - 25 points.
  • Final exam - 55 points. To be allowed to take the final exam, the student has to obtain 20 points during the semester; out of these 20 points, at least five points have to be obtained from the project.

 

 

Controlled instruction

 

Exam prerequisites

Student must have at least 20 points that she/he can achieve during the semester and at least 5 points must be from project implementation assessment.
