Abstract

Gestion d’une mémoire dans un dispositif électronique L’invention vise la gestion d’une première mémoire (MR1) d’un premier dispositif (DV1) coopérant avec un deuxième dispositif (DV2) comportant une deuxième mémoire (MR2). Lors d’un procédé, le premier dispositif (DV1) réalise un chargement initial comprenant : l’acquisition d’une application (APP1) comportant du code interprétable orienté objet définissant des méthodes (MT) exécutables ; et la génération dans la première mémoire (MR1) d’objet-méthode (OBM) ; puis envoie chaque objet-méthode (OBM) au deuxième dispositif électronique (DV2) pour enregistrement dans la deuxième mémoire (MR2). Au cours d’une interprétation du code interprétable de l’application (APP1), le premier dispositif (DV1) identifie les objet-méthodes (OBM1) invoqués puis récupère depuis la deuxième mémoire (MR2) chaque objet-méthode (OBM) invoqué qui n’est pas déjà stockée dans la première mémoire (MR1), pour en permettre un accès par le premier dispositif électronique (DV1). Figure pour l’abrégé : Fig. 1.Management of a memory in an electronic device The invention relates to the management of a first memory (MR1) of a first device (DV1) cooperating with a second device (DV2) comprising a second memory (MR2). During a process, the first device (DV1) performs an initial load comprising: the acquisition of an application (APP1) comprising interpretable object-oriented code defining executable methods (MT); and the generation in the first memory (MR1) of an object-method (OBM); then sends each object-method (OBM) to the second electronic device (DV2) for recording in the second memory (MR2). During an interpretation of the interpretable code of the application (APP1), the first device (DV1) identifies the method-objects (OBM1) invoked then recovers from the second memory (MR2) each method-object (OBM) invoked which is not already stored in the first memory (MR1), to allow access to it by the first electronic device (DV1). Figure for the abstract: Fig. 1.
