Multi-Mode Monitoring for Mixed-Criticality Real-time Systems
2013 (English)In: Proc. 11th International Conference on Hardware/Software Codesign and System Synthesis, New York: ACM Press, 2013Conference paper (Refereed)
We present a scheme for monitoring activation patterns of multiple tasks in mixed-criticality real-time systems. Unlike previous approaches, which enforce a single pre-defined activation pattern bound per task, we propose a multi-mode approach, where monitors can dynamically switch between different configurations, depending on the observed activation pattern at other tasks. The required configurations are based on real-time interfaces which we determine through sensitivity analysis. In an evaluation we show, that switching between monitor configurations allows to dynamically reassign timing slack between tasks and thereby achieve better resource utilization and still provide the same timing guarantees.
