MOESIL: a cache coherency protocol for locked mixed criticality L1 data cache
DS-RT '21: Proceedings of the 2021 IEEE/ACM 25th International Symposium on Distributed Simulation and Real Time ApplicationsArticle No.: 30, Pages 1–8https://doi.org/10.1109/DS-RT52167.2021.9576135The tremendous needs of computing power and predictive timing behaviours of modern systems bring revolutionary changes in memory subsystem architecture. One such improvement is the usage of locked caches to have predictive execution time. The existing ...

MEDIATOR: a mixed criticality deadline honored arbiter for multi-core real-time systems
Multi-core systems are the potential enablers of the overwhelming growth of mixed criticality systems. There exist challenges to the widespread usage of multi-core in mixed criticality systems due to the non-predictive resource access timings. In this ...

MC-ADAPT: Adaptive Task Dropping in Mixed-Criticality Scheduling
ACM Transactions on Embedded Computing Systems (TECS), Volume 16, Issue 5sArticle No.: 163, Pages 1–21https://doi.org/10.1145/3126498Recent embedded systems are becoming integrated systems with components of different criticality. To tackle this, mixed-criticality systems aim to provide different levels of timing assurance to components of different criticality levels while achieving ...

Separation of concerns for dependable software design
FoSER '10: Proceedings of the FSE/SDP workshop on Future of software engineering researchPages 173–176https://doi.org/10.1145/1882362.1882399For 'mixed-criticality' systems that have both critical and non-critical functions, the greatest leverage on dependability may be at the design level. By designing so that each critical requirement has a small trusted base, the cost of the analysis ...
