Self-Aware Scheduling for Mixed-Criticality Component-Based Systems
A basic mixed-criticality requirement in real-time systems is temporal isolation, which ensures that applications receive a guaranteed (CPU) service and impose a bounded interference on other applications. Providing operating system support for temporal isolation is often inefficient, in terms of utilisation and achieved latencies, or complex and hard to implement or model correctly. Correct models are, however, a prerequisite when response times are bounded by formal analyses. We provide a novel approach to this challenge by applying self-aware computing methodologies that involve run-time monitoring to detect (and correct) model deviations of a budget-based scheduler.
