Abstract

Transformation de données vidéo à vitesse élevée et en temps réel. Des mots de n bits de données vidéo représentant une image balayée horizontalement sont chargés séquentiellement en parallèle par rangée dans une mémoire matricielle 40 à n rangées. La mémoire matricielle 40 est déchargée séquentiellement en parallèle par colonne dans un ensemble de registres à décalage 50-57 à une capacité de n x n bits. Chaque cycle de décalage engendre un mot comprenant tous les bits des positions de bit correspondantes dans chacun des registres 50-57. Application aux systèmes de traitement d'images.
