A System on a Chip – The Sequel

The swelling network tide of customers, devices, and business around the globe is putting increasing pressure on vendors to deliver servers with more performance, more network bandwidth, more pervasive security, and more threads. For server vendors, the challenge is meeting all of these requirements within increasingly constrained space and power envelopes. The UltraSPARC T2 processor (code-named Niagara 2) was designed to build on the success of its predecessor, the UltraSPARC T1, and to address these challenges head-on. By scaling performance through threading, and integrating networking, security, and I/O onto the processor itself, the UltraSPARC T2 delivers more throughput, performance, and functionality per watt than any processor in its class.

Innovating@Sun host Hal Stern met with Distinguished Engineer and CTO of Sun Microelectronics, Rick Hetherington to discuss this latest silicon innovation from Sun. Topics covered include:

  • Design choices that make UltraSPARC T2 a true server on a chip
  • New features from the Niagara 1 baseline including a different floating point architecture, memory controller and crypto-interface
  • How we've more than doubled bandwidth and vastly increased capacity
  • How UltraSPARC T2 is “future-proofed”, covering 99.9% of all the encryption and security needs for the market
  • The programming interface
  • Virtualization and OS support
  • Plans for open sourcing
