Scheduling Mixed-Criticality Implicit-Deadline Sporadic Task Systems Upon a Varying-Speed Processor

Abstract

A mixed criticality (MC) workload consists of components of varying degrees of importance (or 'criticalites'). The problem of executing a MC workload, modeled as a collection of independent implicit-deadline sporadic tasks executing upon a preemptive uniprocessor, is considered. Suitable scheduling strategies are devised for scheduling such systems despite uncertainty and unpredictability in both the amount of execution needed by the tasks, and the effective speed of the processor. These scheduling strategies allow for simultaneously making efficient use of platform resources and ensuring the correctness of the more critical workload components at greater levels of assurance.
