Mixed Criticality on Multi-cores Accounting for Resource Stress and Resource Sensitivity

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The most significant trend in real-time systems design in recent
years has been the adoption of multi-core processors and the
accompanying integration of functionality with different criticality levels onto the same hardware platform. This paper integrates mixed criticality aspects and assurances within a multi-core system model. It bounds cross-core contention and interference by considering the impact on task execution times due to the stress on shared hardware resources caused by co-runners, and each task’s sensitivity to that resource stress. Schedulability analysis is derived for four mixed criticality scheduling schemes based on partitioned fixed priority preemptive scheduling. Each scheme provides robust timing guarantees for high criticality tasks, ensuring that their timing constraints cannot be jeopardized by the behavior or misbehavior of low criticality tasks.
