The examinations (including draft answers) of (previous years of) 2IN20 (!):
Examinations (including draft answers) of 2IN25 (!):

· 2IN25 is a 5 ECTS credits BaMa predecessor of 2IN26.
The course addresses basic concepts of real-time systems, presents examples of real-time systems, covers real-time systems analysis and design, and gives an in-depth treatment of timing analysis and scheduling. The course is organized around the issue of real-time requirements and their impact on the architecture of a system. The considered system domain will be networked embedded systems. Applications are drawn from automotive domain (e.g. real-time control) and multi-media applications, such as video streaming.
The course is completed by passing an examination and doing either an assignment or a practical training. The assignment involves studying one or more articles and writing a report. The assignment can be done with groups of 4 or 5 students. These groups must hand in their own, original work, reported by themselves. The practical training involves performing weekly experiments with a set of simple real-time kernels using a simple application.
This year, there are 8 weeks of regular lectures. There will be two regular lectures per week and a tutorial session. The tutorial session consists of two hours. The first hour will be used to discuss exercises. Students are expected to make those assignments prior to the lecture. Answers to the exercises will be made available via OASE. The second hour will be used to discuss the practical training.
On this site the current status of the course will be maintained in terms of the contents, and expected reading. Slides and other material will mostly be available from OASE only.
Course objectives (high-level):
The objective of this course is to bring students into the position to analyze and (partially) design real-time systems, and conduct research in the area of real-time systems.
Course objectives (lower-level):
The student can:
(i) explain and apply the fundamental concepts and terminology of real-time systems;
(ii) explain and address the fundamental problems of real-time systems;
(iii) analyze real-time systems designs;
(iv) design a real-time system (at least partially); and
(v) identify and assess the relevant literature and research trends of real-time systems.
