Abstract

L'invention vise un procédé d'ordonnancement de tâches semi-périodiques. Ces tâches doivent respecter une séquence de lancements périodique. Pour chaque tâche est définie une période d'ordonnancement. Au sein de chaque période est déclarée la séquence des moments de lancement de la tâche. Ainsi, la tâche peut être lancée en respectant une séquence de lancements non périodique. Cette séquence étant, elle, répétée de manière périodique.The invention relates to a method for scheduling semi-periodic tasks. These tasks must follow a periodic launches sequence. For each task is defined a scheduling period. Within each period is declared the sequence of moments of launching the task. Thus, the task can be started respecting a sequence of non-periodic launches. This sequence being repeated periodically.
