Abstract

L'invention concerne un procédé et un appareil de commutation de mode, un dispositif électronique et un système de puce, le procédé consistant à : recevoir une opération d'utilisateur, et en réponse à l'opération d'utilisateur, commuter une application s'exécutant au premier plan d'une première application à une seconde application ; si le temps d'exécution de la seconde application dans le premier plan n'est pas supérieur à une première durée prédéfinie, alors maintenir un premier taux de rafraîchissement de logiciel, la première durée prédéfinie étant la durée prédéfinie correspondant à la seconde application, le premier taux de rafraîchissement de logiciel étant le taux de rafraîchissement de logiciel de la première application, et le taux de rafraîchissement de logiciel étant le taux de rafraîchissement d'une image dans une mémoire cache d'affichage d'un dispositif électronique ; si le temps d'exécution de la seconde application dans le premier plan est supérieur à la première durée prédéfinie, alors commuter le taux de rafraîchissement de logiciel du dispositif électronique du premier taux de rafraîchissement de logiciel à un second taux de rafraîchissement de logiciel, le second taux de rafraîchissement de logiciel étant le taux de rafraîchissement de logiciel de la seconde application. Le problème de la consommation d'énergie élevée de dispositifs électroniques provoqué par une commutation fréquente de la fréquence de rafraîchissement est efficacement résolu.
