Semaphore (116) operation manages exclusive access to a memory (114) that is shared by a plurality of processing elements. Semaphore reservation status for exclusive access by a processing element is (102a), (102b) monitored by a memory controller. To clear an obsolete reservation status, a command signal is transmitted for a write operation to the memory while prohibiting update of the contents of a memory. The reservation status at the controller (104) is changed from a reservation state to a non-reservation state in response to receipt of the command signal.

L'invention se rapporte à l'utilisation de sémaphores pour la gestion de l'accès exclusif à une mémoire partagée par une pluralité d'éléments de traitement. Le statut de réservation de sémaphore assurant à l'élément de traitement un accès exclusif à la mémoire, est surveillé par un contrôleur de mémoire. Le procédé décrit consiste à supprimer un statut de réservation obsolète en transmettant un signal de commande d'écriture à la mémoire, et en empêchant simultanément la mise à jour du contenu de la mémoire. En réponse à la réception du signal de commande, le statut de réservation est modifié et passe d'un état de réservation à un état de non réservation dans le contrôleur.
