Real-Time Programming Languages [WS only]

Embedded systems in a safety-critical context, e.g., controllers in automobiles, software in airplanes and industrial plants, have to work reliably and under timing constraints. Such systems require a level of integrity and availability for which traditional mainstream programming techniques fail to provide appropriate means, or even guarantees. As a result, programming languages with strict semantics and inherent support for timing were developed. They introduce programming models specifically targeted towards developing safety-critical and real-time systems. The aim of this module is to introduce the basic principles for programming such real-time systems, and to gain practical skills with relevant programming languages and verification tools.

First we study why real-time software substantially differs from Desktop applications, and how the development workflow has to be different from Desktop applications. Then we introduce the predominant real-time programming paradigms and highlight their differences. For each of the paradigms we learn the basics of one programming language, in which we solve various programming tasks in the lab. Finally, we explain the theory of functional and temporal verification of real-time software. In this process, we gain a deep understanding how the architectural features of the target platform influence both the temporal and functional correctness of the software, and how both can be analyzed and formally proved.
