MCS-IOV: Real-Time I/O Virtualization for Mixed-Criticality Systems
2019
2019 IEEE Real-Time Systems Symposium (RTSS)
Preserved Fulltext
MCS-IOV extends a real-time I/O virtualisation system, by supporting the concept of mixed criticalities and customised interfaces for schedulers, which offers good timing-preditability. ...
In mixed-criticality systems, timely handling of I/O is a key for the system being successfully implemented and functioning appropriately. ...
Hence, the evaluated metrics mainly focus on resource efficiency, predictability and run-time system mode switch.
