Over one hundred micro-architecture features were analyzed and simulated in order to determine if they should be included in UltraSPARC-I. A fast and flexible performance sim-ulator was developed in order to model these features. In this paper, we describe UPS (UltraSPARC-I Performance Simula-tor), and show how it was used to do trade-off analysis.
UltraSPARC is the first microprocessor from Sun Micro-systems' SPARC Technology Business to implement the new 64-bit SPARC V9 architecture. UltraSPARC is equipped with unique multimedia capabilities and is capable of 4-way superscalar instruction dispatch, with an emphasis on maximal system efJiciency and throughput in the execution of complex,(More)
