Abstract

Dispositif facilitant la purge des tables contenant les adresses réelles correspondant aux adresses virtuelles venant d'être traduites. Le compte du compteur 84 est introduit dans le champ 46a de la table 46 chaque fois qu'une nouvelle traduction est entrée. Le compteur 84 est incrémenté d'une unité après chaque instruction de purge ou d'invalidation Lorsqu'une traduction est extraite de la table 46 le nombre mis en mémoire dans 46a est comparé par 88 au compte actuel du compteur. Si les nombres ne correspondent pas, la traduction n'est pas valide. Grâce à l'invention, les bits de validité de la table 46 sont mis à jour seulement pour le compte total du compteur.
