Abstract

Dans les calculatrices électroniques, les appareils périphériques sont souvent raccordés en série à l'unité de commande centrale à travers une ligne principale de transmission de données. Afin que même dans le cas d'une longue chaîne d'appareils périphériques, le signal d'horloge n'arrive pas plus tôt que le signal de données ayant subi le plus grand retard, mais n'arrive toutefois pas inutilement beaucoup plus tard en vue de pouvoir respecter une vitesse de transport aussi élevée que possible. Application : calculatrices électroniques.
