Abstract

Procédé de commande d’une unité de contrôle moteur qui comporte au moins deux cœurs de microprocesseur, comportant des étapes d’exécution d’une sous-tâche mère (FA1, FB1) et au moins une sous-tâche fille (FA2, FB2). Le procédé comporte les étapes suivantes : - déterminer le nombre d’exécutables (R) qui restent à exécuter dans la dernière sous-tâche fille (FA2) de la première période (9A), lorsque la sous-tâche mère (FB1) de la deuxième période (9B) démarre ; - déterminer le nombre d’exécutables (R) déjà exécutés dans la sous-tâche mère (FB1) de la deuxième période (9B), lorsque la dernière sous-tâche fille (FA2) de la première période (9A) se termine.
