Abstract
L’invention propose un module destiné à servir de mémoire tampon entre un premier système générant des données à un premier débit et un deuxième système consommant des données à un deuxième débit. Alors que le module émule le fonctionnement d’une mémoire tampon ayant recours à un élément de mémoire à accès aléatoire à deux ports (entrée/sortie), le module proposé se limite à l’utilisation d’un tel élément de mémoire à port d’entrée/sortie combiné unique. (Fig. 1)
