Information technology — Intelligent Peripheral Interface — Part 3: Device generic command set for magnetic and optical disk drives
La présente partie de l'ISO/CEI 9318 décrit l'interface de niveau logique 3 (niveau générique) pour les unités de disques magnétiques et optiques. Voir l'article 6 de l'ISO/CEI 9318-1 pour une explication des niveaux. Les caractéristiques physiques, électriques et celles de la configuration ainsi que les protocoles de transmission de cette interface sont conformes à l'ISO/CEI 9318-1. L'interface est capable de gérer les vitesses de transfert de données de 0 à 10 Moctets/s, en fonction de la classe du contrôleur et du récepteur. L'objet de la présente partie de l'ISO/CEI 9318 est de faciliter le développement et l'utilisation d'une interface intelligente qui permet la connexion à un contrôleur de périphériques de plusieurs types tels que disques, bandes, communications. La présente partie de l'ISO/CEI 9318 ne remplace pas des normes existantes mais apporte un complément aux autres normes d'interface pour périphériques intelligents (IPI) (voir article 2). La présente partie de l'ISO/CEI 9318 fournit une définition d'une partie générique appareil, d'une famille de normes appelées «interface pour périphériques intelligents (IPI)», interface parallèle tous usages, à hautes performances. L'intention de IPI est d'isoler l'hôte (CPR), autant du point de vue matériel que logiciel, des changements dans les périphériques, en fournissant un jeu de commandes 1607 de «fonctions génériques» permettant la connexion de multiples types de périphériques (disques, bandes, imprimantes, communications). Pour assouplir la transition entre la méthode actuelle et l'approche générique, IPI supporte des jeux de commandes spécifiques à un appareil, comme celui-ci, pour aider à établir une passerelle entre les deux approches. Pour réaliser cet ensemble d'objectifs, la définition de IPI inclut des jeux de commandes spécifiques appareil et génériques appareil, utilisant tous les deux le même «bus» commun. Le jeu de commandes spécifiques appareil fournit : des
