Time-Triggered Scheduling for Multiprocessor Mixed-Criticality Systems

Real-time safety-critical systems are getting more complex by integrating multiple applications with different criticality levels on a single platform. The increasing complexity in the design of mixed-criticality real-time systems has motivated researchers to move from uniprocessor to multiprocessor platforms. In this paper, we focus on the time-triggered scheduling of both independent and dependent mixed-criticality jobs on an identical multiprocessor platform. We show that our algorithm is more efficient than the Mixed criticality Priority Improvement (MCPI) algorithm, the only existing such algorithm for a multiprocessor platform.
