vci_mem_cache_v4.cpp @ 140

Last change on this file since 140 was 140, checked in by kane, 14 years ago

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