S2io becomes Neterion in early 2005

S2io Licenses Tensilica’s Xtensa Cores For Innovative Line of 10 Gbps Ethernet Connectivity Products

Xtensa Simplifies the Design of Highly Complex, Customized Networking Solution

SANTA CLARA, Calif., June 16, 2003 – Tensilica, Inc. the leading supplier of configurable and extensible microprocessor cores, today announced that hot start-up S2io, Inc. has licensed the Xtensa® V core for a new family of storage-connectivity products. S2io is developing next generation 10 Gigabit Ethernet networking products for high performance server and network storage environments.

“A development of this complexity would be very difficult without the use of Tensilica’s design methodology,” Dave Zabrowski, President and CEO of S2io, stated. “By taking advantage of Tensilica’s automated approach to customizing the processor, we can get the speed we need with lower power and smaller die size. Xtensa will allow us to design innovative, high-performance 10 Gbps Ethernet networking products and establish an early lead in this emerging market.”

S2io has received significant attention for its unique approach to overcoming the performance and cost bottlenecks that exist in today’s compute server and networked storage environments. The company is combining its extensive knowledge of high-speed networking architectures with cost-effective, pervasive Ethernet technology to dramatically lower the cost and improve the performance of network storage. S2io recently began sampling its first generation product. The company’s solid management team consists of experts with broad backgrounds in the semiconductor, computer and networking industries. S2io recently closed a second funding round totaling $18 million.

“S2io is one of the most promising start-ups in the high performance server and storage networking market,” said Chris Rowen, President and CEO for Tensilica. “This agreement not only proves the cost and time-to-market advantages that can be achieved using the Xtensa configurable and extensible processor, but also shows that Xtensa can be used to reach performance levels required for 10 Gbps Ethernet.”

Tensilica has been a pioneer in delivering a microprocessor platform that offers both configurability and extensibility – the process of extending the processor by adding custom, designer-defined instructions or execution units. Tensilica’s solution is unique because it includes the patented Xtensa Processor Generator, which automatically generates the processor’s hardware implementation and software development tools simultaneously, even in cases where designer-defined instructions are added using Tensilica’s TIE language. Tensilica is currently the only company offering this level of automation in processor design. Comparable platforms require designers to manually adjust compilers, assemblers, debuggers, operating systems, instruction set simulators, co-verification models and EDA implementation scripts when hardware changes are made to the processor RTL, significantly increasing design time, program cost and product risk.

Licensed by over 55 of the industry's leading semiconductor and systems companies, Tensilica's patented Xtensa microprocessor technology enables designers to deliver a wide variety of optimized SoCs for applications ranging from low-cost, low-power consumer electronics devices to high performance, multi-processor communications systems. The Xtensa architecture provides a powerful, integrated hardware and software development environment with thousands of configuration options and an unlimited range of customer-specific extensions. Because these instructions are recognized as "native" by a complete set of software development tools, developers can simultaneously tune both application software and processor hardware to meet specific speed, power and feature goals.
