L.: Really Hard Time developing Hard Real Time

Abstract: The development process of distributed real-time embedded systems (DRES) suffers significant limitations when addressing the antagonistic concerns of systems interoperability, flexibility, and reliability. In this paper, we first present a component-based development process and related architecture designed to enable DRES interoperability while improving developer productivity. We then describe the techniques this process uses in order to improve reliability of these systems. The component-based framework is illustrated by a practical use case. Lastly, we present research orientations addressing verification, validation, and certifiability on the one hand, and their ability to tackle with the always-growing flexibility requirements on the other hand. As real time embedded systems complexity is growing every year, industry software architects are facing major challenges in terms of development productivity. This issue is addressed by component-based development methodologies, as proposed by the software engineering academic community [1].
