Patent

CA 2294245

The invention concerns a device for exchanging asynchronous data between two microprocessors (10, 20) through an interface consisting of a random access memory (30). The invention is characterised in that said random access memory has a single access controlled by one of said microprocessors, called master microprocessor (10). Each instruction executed by said master microprocessor comprises execution cycles followed by at least two read-write data exchange cycles with the second microprocessor, called slave microprocessor (20) and the master microprocessor (10) is capable of prolonging the slave microprocessor (20) access time to the random access memory until the end of the last data exchange cycle (AM-R).

Dispositif d'échange de données asynchrones entre deux microprocesseurs (10, 20) par l'intermédiaire d'une interface constituée par une mémoire (30) à accès aléatoire. Selon l'invention, ladite mémoire (30) à accès aléatoire est du type à simple accès, lequel est contrôlé par l'un desdits microprocesseurs, dit microprocesseur-maître (10). Chaque instruction exécutée par ledit microprocesseur-maître comporte des cycles d'exécution suivis d'au moins deux cycles d'échange de données en lecture/écriture avec le deuxième microprocesseur, dit microprocesseur-esclave (20), et le microprocesseur-maître (10) est apte à allonger le temps d'accès du microprocesseur-esclave (20) à la mémoire (30) à accès aléatoire jusqu'à la fin du dernier cycle (AM-R) d'échange de données.
