Translating end-to-end timing requirements to timing analysis model in component-based distributed real-time systems
Saad Mubeen, Jukka Mäki-Turja, Mikael Sjödin · ACM SIGBED Review · 2012
Often, component-based real-time systems are modeled with trigger and data chains. The end-to-end timing requirements on trigger chains are different from those on data chains. For a trigger chain, the interest lies in the calculation of holistic response time and its comparison with end-to-end deadline. Whereas, the schedulability of a data chain requires a comparison between its end-to-end latencies and corresponding deadlines. We discuss the problem of translating end-to-end timing requirements unambiguously from component-based real-time systems into timing analysis models which are required as input by the analysis tools. We also provide preliminary guidelines for such translations in the existing industrial tool suite.
