Programming Embedded Systems at BTH 2006

This course will be held at Blekinge Tekniska Högskola.


Prof. Dr. habil. Andreas Polze, Hasso-Plattner-Institute

Dipl.Inf. Andreas Rasche, Hasso-Plattner-Institute


In context of the Erasmus/Sokrates cooperation between the Hasso Plattner Institute for Software Engineering in Postdam and the Blekinge Institute of Technology, we are announcing our mini-course on "Programming Embedded Systems". The course will be comprised of two units: a lecture series in early October and a series of hands-on labs in later October. Both units will be held at Blekinge Tekniska Högskola. The lab assignments will access the "Distributed Control Lab", a testbed infrastructure at HPI over the internet.

The lecture series (12 hours) will be given from October 3, 2006 to October 6, 2006. Additional labs and consultations will take place on October 10 and 18. Successful attendees of both, lectures and labs will earn a total of 3 ETCS credit points.

The mini-course can be taken in combination with the Embedded Systems (DVB018). Successful completion of the "Programming Embedded Systems" course will result in a bonus in the DVB018 final exam.

Prospective attendees may also want to consider combining the mini-course on "Programming Embedded Systems" with another mini-course on Windows operating system architecture to be given by Prof. Dr. Andreas Polze in spring 2007. Both mini-courses will earn a total of 7.5 ETCS credit points.

Course Description:

Programming embedded control software has to address a number of issues, which are less important in classical desktop settings. These issues include predictable (real-time) timing behaviour, resource (memory and network) usage, support for predictable communication protocols, power consumption, user-interface design (support for headless operation), system configuration, and programming languages and models. In addition non-functional properties such as security and fault-tolerance must be addressed during software development.

Within the course state-of-art programming models, languages and operating systems will be presented and practically demonstrated at the Distributed Control Lab (DCL). The DCL is a remote laboratory operated at the Hasso-Plattner-Institute at University of Potsdam, Germany. The Lab provides remote access to real-time control experiments, which will be used for accompanying practical exercises, that teaches the above-mentioned aspects of embedded systems programming based on a number of case studies

Course Schedule & Location:

The course will be held in week 40, 2006. More information about time and location can be found here.
