UltraSPARC™-II CPU Module

SME5224AUPA-400400 MHz CPU, 4.0 MB E-Cache

CPU DESCRIPTION

UltraSPARC-II CPU

The UltraSPARC™-II CPU is the second generation in the UltraSPARC™ s-series microprocessor family.

A complete implementation of the SPARC™ V9 architecture, it has binary compatibility with all previous ver- sions of the SPARC™ microprocessor family.

The UltraSPARC™-II CPU is designed as a cost effective, scalable and reliable solution for high-end worksta- tions and servers. Meeting the demands of mission critical enterprise computing, theUltraSPARC™-II CPU runs enterprise applications requiring high data throughput. It is characterized by a high integer and floating point performance: optimally accelerating application performance, especially multimedia applications.

Delivering high memory bandwidth, media processing and raw compute performance, the UltraSPARC™-II CPU incorporates innovative technologies which lower the cost of ownership.
