Product Information

The state-of-the-art UltraSPARC II processor is the second generation in the UltraSPARC s-series microprocessor family. A complete implementation of the SPARC V9 architecture, the UltraSPARC II processor is binary compatible with all previous versions of SPARC processors, resulting in an increased return on your investment. Designed for scalability from mainstream workstations at the low end up to supercomputing servers at the high end, the UltraSPARC II processor delivers high performance and reliability. Meeting and exceeding the demands of today's compute-intensive, network-centric, multimedia-rich applications, the UltraSPARC II processor implements innovative technologies that help lower the end user's total cost of ownership. The UltraSPARC II processor micro architecture is designed to provide up to 4-way glue less multiprocessing support and supports up to 64-way systems. The processor supports multiple L2 cache speeds and sizes to enable high-performance multiprocessing systems. A highly scalable, high-performance system interconnect ensures a bottleneck-free computing environment resulting in high memory bandwidth. VIS (Visual Instruction Set) multimedia extensions boost the performance of graphics-intensive multimedia applications, and thus reduce overall system costs by eliminating the need for a special-purpose media processor. And the UltraSPARC II delivers superior raw compute performance by using the most innovative RISC microprocessor architecture and state-of-the-art process technology. The UltraSPARC II processor not only helps the system designer by implementing industry-standard testing and instrumentation interfaces, it also uses Error Checking and Correction (ECC) and parity to increase system reliability. With high performance, high scalability, and high reliability, the UltraSPARC II is the processor of choice for today's workstations and servers.
