| Abstract(in English) | In this paper, we deal with the problem of scheduling task sets, consisting of "occasionally skippable" firm periodic tasks on open real-time systems. We extend the Skip-Over model to deal with tasks that have generous time constraints. We design and implement a scheduler that exploits skips to manage flexible time constraints. We propose a hardware priority assignment technique to reduce missing deadlines of important tasks on RMT Processors. Simulation results show that the deadline miss ratio decreases to about 22.2% in the maximum by considering priorities among threads when the system falls into overloaded conditions. |
