Abstract

Current adaptive mixed criticality scheduling policies assume
a high criticality mode in which all low criticality tasks are descheduled to ensure that high criticality tasks can meet timing constraints derived from certification approved methods. In this paper we present a new scheduling policy, Adaptive Mixed Criticality - Weakly Hard, which provides a guaranteed minimum quality of service for low criticality tasks in the event of a criticality mode change. We derive response time based schedulability tests for this model. Empirical evaluations are then used to assess the relative performance against previously published policies and their schedulability tests.
