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.
The paper discusses the benefits of microprocessor-based distributed processing systems, which are greater than those of conventional timeshared mini or main-frame systems. It highlights the advantages of the NS16000 microprocessor family for this application, and it explains how the NS16000 operating system supports distributed processing.
