N2 - This paper extends analysis of the Adaptive Mixed Criticality (AMC) scheme for fixed-priority preemptive scheduling of mixed-criticality systems to include tasks with arbitrary deadlines. Both of the previously published schedulability tests, AMC-rtb and AMC-max are extended to cater for tasks with deadlines that may be greater than their periods. Evaluations show that the simpler method, AMC-rtb-Arb, remains a viable approach that performs almost as well as the more complex alternative, AMC-max-Arb, when tasks with arbitrary deadlines are considered.
