Abstract

Procédé et dispositif de dimensionnement d’une mémoire d’un calculateur L’invention concerne un procédé et un dispositif de détermination de la taille d’un espace mémoire d’un premier calculateur (11) d’un système embarqué (100). Pour cela, une première requête est reçue, par exemple d’un dispositif d’un système externe (10) au véhicule. La première requête comprend avantageusement une première information représentative d’une fréquence d’acquisition de données d’un capteur (132) associé au système embarqué, un identifiant du capteur (132) et une deuxième information représentative d’un temps de transmission de données entre le premier calculateur (11) et un dispositif récepteur des données. Le dispositif récepteur des données correspond par exemple à un dispositif du système externe (10). La taille de la mémoire est déterminée en fonction de la première information et de la deuxième information. Figure pour l’abrégé : Figure 1Method and device for dimensioning a memory of a computer The invention relates to a method and a device for determining the size of a memory space of a first computer (11) of an on-board system (100). For this, a first request is received, for example from a device of an external system (10) to the vehicle. The first request advantageously comprises a first item of information representative of a data acquisition frequency of a sensor (132) associated with the onboard system, an identifier of the sensor (132) and a second item of information representative of a data transmission time. between the first computer (11) and a data receiving device. The data receiving device corresponds for example to a device of the external system (10). The size of the memory is determined according to the first information and the second information.
