yAjout du multi_cache : plusieurs processeur peuvent ce partager le même cache L1.
2 remarques, (1) deux nouveaux paramètres : nb_cpu, nb_cache. Pour avoir un cache dont le comportement est identique à la version d'avant, mettre ces paramètres à 1.
(2) le port d'interruption est maintenant un tableau dépendant du nombre de processeur.
Voir le fichier "platforms/caba-ring-ccxcachev4_memcachev4-mips32el/top.cpp" pour plus de détails.
