CA 2381191

The system comprises a first processor, a second processor and non-volatile memory. The non-volatile memory stores messages being transferred between the first and second processors. The non-volatile memory is resettably and logically decoupled from first and second processors to preserve the state of the first and second processors and the messages in the event of a loss of communication or a processor reset. The non-volatile memory increases the rate of message transfer by transferring blocks of messages between the non- volatile memory and the second processor. The non-volatile memory includes status and control registers to store the state of messages being transferred, message queues, and first and second processors. The system may also include a local power source to provide power to the non-volatile memory.

L'invention concerne un système comprenant un premier processeur, un second processeur et une mémoire non volatile. La mémoire non volatile assure le stockage des messages transférés entre le premier et le second processeur. La mémoire non volatile est coupée de façon réinitialisable et logique du premier et du second processeur, de manière à conserver l'état du premier et du second processeur ainsi que les messages en cas de perte d'une communication ou de réinitialisation des processeurs. La mémoire non volatile permet d'augmenter la vitesse de transfert des messages par le transfert du blocs de messages entre la mémoire non volatile et le second processeur. La mémoire non volatile comprend des registres d'état et de commande, qui servent à stocker l'état des messages en cours de transfert, des files de messages et du premier et du second processeur. Le système selon l'invention peut également comprendre une source d'alimentation locale destinée à l'alimentation de la mémoire non volatile.
