On completion of the course students will be able to

  • program embedded applications
  • understand and use a kernel to support concurrency, real-time and reactivity
  • design, structure and analyse programs for embedded systems
  • explain different mechanisms for communication and synchronisation between processes
  • explain characteristics of real-time systems and constructions to deal with them in programs
  • compare, select and apply programming language constructs designed for concurrency and real-time


Taking part in the lab is mandatory and one cannot pass the course without doing the practicals. In addition, there will be a final written examination. During the lectures, some bonus questions will be asked, each of which will contribute 0.1 mark to the final mark (can come in handy when rounding up).

Groups for Practicals

Studying, Summarising and Presenting Research Papers

In the second half of the course, two groups of students (thus, 4 people) join to read, summarise and present one of the papers in the provided collection

The presentations will be held during the last two lectures. The structure of the report and the presentation will be posted here and discussed during the lectures. The summary reports are to be typeset in LaTex using this template.

The deadline for submitting the summary reports is October 25, 12:00. The summaries should be sent by email to the lecturer of the course (m.taromirad@hh.se).

Please email your presentations before 12:00 on the day of presentation (October 18 or October 20) to the lecturer of the course.

Resources for C Programming

Recommended Text

We will occasionally use / refer to parts of the following books:

These are only optional resources for the course.

Raspberry PI

For the first half of the course, we will use the Raspberry PI board. The boards will be provided at the lab and you will have access to the lab even outside lab hours. However, if you would like to have your own Raspberry PI and have a lot of fun, you can buy a Raspberry PI B+ board (e.g., from [1], which usually includes also a Micro SD card). You need to buy/have your own micro USB adapter. In order to use a computer display you need an HDMI cable or a converter to the appropriate input for your display monitor.


The course is based on the earlier editions of the course given by Mohammad Mousavi and Veronica Gaspes. Also, the material provided by Johan Nordlander has been essential in the set up of this course.
