Another paper written with my former colleagues at CISTER has been accepted. The paper is entitled “Mixed-criticality Scheduling with Memory Bandwith Regulation” and appear at DATE 2018. The paper considers the problem that existing schedulability analyses for mixed-criticality multi-core systems do not consider task interference in shared platform resources, such as memories, potentially making them optimistic and unsafe. We address this issue by formulating a schedulability analysis for mixed-criticality fixed-priority-scheduled multi-core systems using per-core memory access regulation. We also propose multiple heuristics for memory bandwidth allocation and task-to-core assignment. The analysis and heuristics are implemented in a tool and evaluated through extensive experiments.
