Abstract
(EN)
The invention relates to a cache memory and method for controlling access to data. According to the invention, a control area which is advantageously formed separate from a data area (410) is provided for controlling the access to data stored in the cache and to be read by applicative processes. The control area comprises at least one release area (430) with offsets (442) and data version definition sections (452, 454, 456). Application to shared memories for client server architectures.

L'invention concerne une mémoire cache et un procédé servant à contrôler l'accès aux données. Selon l'invention, une aire de contrôle qui est avantageusement formée séparément d'une aire de données (410) sert à contrôler l'accès aux données mémorisées dans le cache et lisibles par des processus applicatifs. L'aire de contrôle comprend au moins une aire de libération (430) avec des décalages (442) et des sections de définition de version de données (452, 454, 456). Application à des mémoires partagées pour les architectures de serveur client.
