Abstract
Le circuit intégré (CI) comprend une unité de traitement (13) configurée pour démarrer avec un jeu d’instructions de démarrage, puis pour déterminer la taille des instructions d’un programme applicatif (APP) et éventuellement redémarrer sur sa propre initiative, en étant reconfigurée, afin qu’elle exécute les instructions du programme applicatif. Une seule mémoire de démarrage est par conséquent nécessaire. Figure pour l’abrégé : Fig 1
