Teaching methods

Lectures: theory and exercises, meant to be highly interactive. Practical LAB sessions on Unix processes, synchronization, and on the RTAI real-time operating system.

Assessment methods

There are two possibilities for taking the exam: either with midterms+final written exam, or with a single standard written exam. 

The exam consists of open questions, quizzes, exercises, and code analysis. 

Optionally, students who have passed the written exam can also take an oral exam. An optional project or programming assignments may also contribute to the final grade.

Teaching tools

Lectures slides are available to students via the AMS Campus university intranet
