Abstract

L'invention concerne les systèmes informatiques. Dans un processus du type pipeline, chaque étage de traitement PU1, PU2, ... est associé à une copie des registres spécialisés- (accumulateur, compteur ordinal, etc). Chaque fois qu'un étage de traitement met à jour un registre, il positionne un indicateur. Ces indicateurs permettent de faire en sorte que les différents étages n'utilisent que les versions les plus récentes du contenu de chaque registre, en prenant en considération les mises à jour éventuelles par les étages suivants. Application aux ordinateurs de grande puissance.
