| dbo:abstract | Der IBM RS64 ist eine 64-Bit-Prozessorfamilie, die in den späten 1990er Jahren in IBMs RS/6000- und AS/400-Servern eingesetzt wurde. (de) The IBM RS64 is a family of microprocessors used in IBM's RS/6000 and AS/400 servers in the late 1990s. These microprocessors implement the "Amazon", or "PowerPC-AS", instruction set architecture (ISA). Amazon is a superset of the PowerPC instruction set, with the addition of special features not in the PowerPC specification, mainly derived from POWER2 and the original AS/400 processor, and has been 64-bit from the start. The processors in this family are optimized for commercial workloads (integer performance, large caches, branches) and do not feature the strong floating point performance of the processors in the POWER family, its sibling. The RS64 family was phased out soon after the introduction of the POWER4, which was developed to unite the RS64 and POWER families. (en) Le RS64 ou PowerPC-AS est une gamme de processeurs 64 bits produits par IBM dans les années 1990 et utilisés dans les RS/6000 et AS/400. Ces microprocesseurs implémentent l'architecture appelée "Amazon" ou "PowerPC-AS". Amazon est un sous-ensemble du jeu d'instruction du PowerPC. Les processeurs de cette famille sont optimisés pour une charge applicative de type "gestion" (calculs sur les entiers, cache importante) mais n'apportent pas des performances en virgule flottante. La famille RS64 a été remplacée à l'arrivée du POWER4, qui avait été développée pour unifier les familles RS64 et PowerPC. (fr) L'IBM RS64 è una famiglia di microprocessori prodotta da IBM per la sua linea di server AS/400 e RS/6000. I processori erano ottimizzati per lo svolgimento dei compiti commerciali (prestazioni sugli interi, larghe cache, gestione salti) e non avevano caratteristiche come un'unità in virgola mobile potente come la famiglia POWER da cui derivano. Questi processori derivavano dai processori PowerPC ma includevano delle caratteristiche aggiuntive e fin dal primo modello furono progettati a 64 bit.
