Abstract

L'invention concerne un procédé, un dispositif, un équipement et un système de partage de données, le procédé comprenant les étapes suivantes : un équipement divise une mémoire partagée en une première zone et en une deuxième zone au moyen d'un premier processeur (S301), la première zone étant utilisée pour stocker des données de service acquises par le premier processeur, et la deuxième zone étant utilisée pour stocker un message contenant l'adresse des données de service ; l'équipement sollicite dynamiquement une troisième zone dans la première zone au moyen du premier processeur de manière à stocker des premières données de service, et stocke un premier message comprenant l'adresse des premières données de service dans la deuxième zone (S302), les premières données de service étant des données dans les données de service, et le premier message étant un message dans la deuxième zone ; et l'équipement lit le premier message dans la deuxième zone au moyen du second processeur de façon à lire l'adresse des premières données de service dans le premier message, et lit les premières données de service au moyen de l'adresse ainsi lue des premières données de service (S303). Avec le procédé décrit, les copies de données de service peuvent être réduites, et l'efficacité de traitement des données du système et le débit du système sont améliorés.
