Method for real-time execution of a task by a digital signal processor

摘要: L'invention concerne un procede d'execution d'une tâche en temps reel par processeur de traitement numerique du signal (TNS) utilisant une memoire cache, duree globale (T) etant allouee a l'execution ladite et d'interruptions provenant des peripheriques associes au processeur, caracterise ce que la est partagee pluralite d'intervalles temporels comprenant moins periode masquee (T M ) pendant laquelle executee les interruptions placees attente groupees, non N suspendue le groupe execute. The invention relates to method of executing real-time task by digital processor (DSP) using cache memory, total duration is allocated the execution said and interrupts from devices associated with processor, characterized in that divided into plurality time intervals comprising at least one masked period M) which performed queued grouped, unmasked N) suspended carried group. Les periodes masquees sont definies mecanisme materiel temporisation. Masked periods defined material delay mechanism.
