Abstract

La présente demande concerne un procédé de génération de retard et un dispositif associé. Le procédé consiste : à recevoir des informations de temps de retard d'un fil d'état d'utilisateur en provenance d'un programme d'application, les informations de temps de retard étant utilisées pour indiquer une première durée pendant laquelle le fil d'état d'utilisateur doit être retardé, et la première durée allant d'un moment de démarrage à un moment cible; et en fonction des informations de temps de retard, à commander un processeur, qui exécute le fil d'état d'utilisateur, pour entrer dans un état de faible puissance pendant la première durée, le fil d'état d'utilisateur étant maintenu dans un état de fonctionnement pendant la première durée. Au moyen de la présente demande, un processeur peut être commandé pour générer un retard de haute précision et de faible puissance pour un programme d'application.
