DOI: 10.1007/s11241-017-9287-2
Abstract: The current literature of fixed-priority scheduling algorithms relies on sufficient tests to determine if a set of mixed-criticality sporadic tasks is schedulable on a single processor. The drawback of these safe tests is their pessimism,… read more here.

DOI: 10.1007/s11241-018-9323-x
Abstract: In mixed-criticality scheduling, the widely adopted mode-switch scheme assumes that both high- and low-criticality tasks are schedulable when no tasks overrun (normal mode) and all high-criticality tasks are schedulable even when they overrun (critical mode,… read more here.

DOI: 10.1007/s11241-019-09330-2
Abstract: Many existing studies on mixed-criticality (MC) scheduling assume that low-criticality budgets for high-criticality applications are known apriori. These budgets are primarily used as guidance to determine when the scheduler should switch the system mode from… read more here.

DOI: 10.1109/mits.2018.2880270
Abstract: Historically, automotive test systems were designed for single core architectures on both the Electronic Control Unit (ECU) and the Verification and Validation (V&V). This, however, limited the utilization of shared resources, such as memory management… read more here.

DOI: 10.1109/tc.2022.3197078
Abstract: While traditional real-time systems analysis requires single pessimistic estimates to represent system parameters, the mixed-criticality (MC) design proposes to use multiple estimates of system parameters with different levels of pessimism, resulting in low critical workloads… read more here.
