Abstract

Selon des modes de réalisation, la présente invention concerne un procédé et un dispositif d'éveil de processeur d'application appliqués à un terminal mobile. Le procédé consiste : à détecter d'abord si le terminal mobile est dans un premier état prédéfini ; lorsqu'il est déterminé que le terminal mobile est dans le premier état prédéfini, à obtenir une instruction à rapporter qui doit être rapportée à un processeur d'application et la priorité de l'instruction à rapporter ; et si la priorité de l'instruction à rapporter est supérieure à une priorité prédéfinie, à rapporter l'instruction à rapporter au processeur d'application pour éveiller le processeur d'application, de telle sorte que le processeur d'application exécute une opération correspondante. Au moyen de la solution des modes de réalisation de la présente invention, lorsqu'une instruction à rapporter ayant une priorité supérieure à une priorité prédéfinie est obtenue, l'instruction à rapporter est rapportée au processeur d'application ; ainsi, le nombre de fois que les instructions sont rapportées au processeur d'application est réduit, de telle sorte que le nombre de fois où le processeur d'application obtient des instructions est réduit, ce qui empêche que le processeur d'application soit fréquemment éveillé, et résout le problème existant dans l'état de la technique.
