CMU / SEI-89-TR-11 ESD-TR-89-19 Scheduling Sporadic and Aperiodic Events in a Hard Real-Time System

A real-time system consists of both aperiodic and periodic tasks. Periodic tasks have regular arrival times and hard deadlines. Aperiodic tasks have irregular arrival times and either soft or hard deadlines. In this paper, we present a new algorithm, the Sporadic Server algorithm, that greatly improves response times for soft-deadline aperiodic tasks and… CONTINUE READING
