Abstract
This paper presents a connection between two real-time models: a deadline-based model and a latency-based model. The importance of the latency-based model is proved through a result showing that two deadlines, instead of a latency constraint, over-constrain the real-time applications. Moreover, we give a deadline-marking algorithm based on the relation between deadlines and latency constraints. This algorithm provides non-preemptive feasible schedules for systems with precedence constraints and deadlines, or more complex systems with deadlines and latencies. This is the first step toward non-preemptive schedulability for distributed architectures (without over-constraining the system) like, for example, the automotive applications using protocols such as Controller Area Network (CAN).

The importance of the latency-based model is proved through a result showing that two deadlines, instead of a latency constraint, over-constrain the real-time applications. Moreover, we give a deadline-marking algorithm based on the relation between deadlines and latency constraints. This algorithm provides non-preemptive feasible schedules for systems with precedence constraints and deadlines, or more complex systems with deadlines and latencies. This is the first step toward non-preemptive schedulability for distributed architectures (without over-constraining the system) like, for example, the automotive applications using protocols such as Controller Area Network (CAN).</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Grand Est</li><li>Lorraine (région)</li><li>Provence-Alpes-Côte d'Azur</li></region><settlement><li>Nancy</li><li>Nice</li></settlement><orgName><li>Institut national polytechnique de Lorraine</li><li>Université Nancy 2</li><li>Université Nice Sophia Antipolis</li><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Cucu, Liliana" sort="Cucu, Liliana" uniqKey="Cucu L" first="Liliana" last="Cucu">Liliana Cucu</name></region><name sortKey="Pernet, Nicolas" sort="Pernet, Nicolas" uniqKey="Pernet N" first="Nicolas" last="Pernet">Nicolas Pernet</name><name sortKey="Sorel, Yves" sort="Sorel, Yves" uniqKey="Sorel Y" first="Yves" last="Sorel">Yves Sorel</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
