Title (EN) PERMITTING UNABORTED PROCESSING OF TRANSACTION AFTER EXCEPTION MASK UPDATE INSTRUCTION
(FR) AUTORISATION DE TRAITEMENT NON INTERROMPU DE TRANSACTION APRÈS INSTRUCTION DE MISE À JOUR DE MASQUE D'EXCEPTION
Abstract:
(EN) A data processing apparatus has processing circuitry with transactional memory support circuitry to support execution of a transaction using transactional memory. In response to an exception mask updating instruction which updates exception mask information to enable at least one subset of exceptions which was disabled at the start of processing of a transaction, the processing circuitry (4) permits un-aborted processing of one or more subsequent instruction of the transaction that follow the exception mask update instruction.
(FR) Selon l'invention, un appareil de traitement de données comprend de la circuiterie de traitement avec de la circuiterie de prise en charge de mémoire transactionnelle permettant de prendre en charge l'exécution d'une transaction en utilisant de la mémoire transactionnelle. En réponse à une instruction de mise à jour de masque d'exception qui met à jour des informations de masque d'exception pour activer au moins un sous-ensemble d'exceptions qui a été désactivé au début du traitement d'une transaction, la circuiterie de traitement (4) permet un traitement non interrompu d'une ou de plusieurs instructions ultérieures de la transaction qui suivent l'instruction de mise à jour de masque d'exception.
