RMI Unleashes the Highest Performing Multi-core Processor and Product Family in the Industry, Driving System and Performance Scalability

Superscalar XLP Processor Performs at Greater than 2.0GHz and provides a 3x Performance per watt improvement over previous generation processor

Cupertino, California – May 19, 2009 — At Interop 2009, RMI Corporation, a leading provider of high-performance processors for communication and media rich applications, announced the industry’s highest performing Multi-core Processor family driving unmatched system and performance scalability. The superscalar XLP™ Processor utilizes a MIPS64® compatible superscalar, simultaneously multi-threaded processor core with out-of-order processing capabilities. The newly designed core operates at greater than 2.0 GHz and provides embedded system designers their first opportunity to employ an SoC with an integrated best-in-class processor core architecture, optimized for both data plane and control plane processing. RMI’s latest offering delivers the most advanced and highly integrated multi-core processor solution in the industry. The XLP Processor family is developed on a 40nm process technology.

“The XLP Processor is a significant milestone for RMI on the way to becoming the leading communication processor company in the industry. The overwhelming support of our partners in this endeavor is recognition of our leadership architecture,” said Behrooz Abdi, president and chief executive officer, RMI. “The combination of our high performance architecture and advanced 40nm technology will put us significantly ahead of the competition and allow our customers to further differentiate themselves in their market segments.”

EC4400™ Processor Core
The EC4400 Processor Core contained in the XLP Processor is architected to provide the highest performance for both data plane and control plane performance. Each EC4400 Core maintains the multi-threading capability that is field proven to provide the highest possible performance for throughput oriented data plane processing. In order to demonstrate similar leadership in single context control plane processing, RMI designed the EC4400 Core as a superscalar engine with out-of-order execution capabilities. This combination of quad-issue and simultaneous 4-way multi-threading within each core enables new classes of systems with non-compromised combined data plane and control plane performance with a single chip solution.

Each of the four hardware threads (VirtuCores™) embedded in the EC4400 Core appears to software as a completely separate processing element, enabling extremely flexible software architectures that simultaneously simplify the software development while increasing the overall system performance. RMI’s innovative hardware multi-threading capabilities are proven to deliver unparalleled performance in data plane applications that are inherently sensitive to memory latencies. The EC4400 Core is MIPS64® Release-II ISA-compliant and contains an IEEE754 and MIPS-compliant floating point unit per core. Through the combination of architectural improvement and frequency enhancement, the EC4400 offers a 3x performance per watt improvement over RMI’s industry leading current generation product offering and was designed based on inputs from leading systems providers.

“We are pleased with the results we have obtained through our work with RMI and look forward to further collaboration,” said Brian Nadeau, director EqualLogic storage engineering. “RMI’s multi-core processors, including the new XLP Processor, bring exceptional performance and scalability to our EqualLogic storage systems.”

The XLP832 Processor
The RMI XLP832 Processor is a highly-scalable Super System-on-Chip (SuperSoC™) device incorporating key functions of a high-end communication system, including wired and wireless security, networking, storage, data center acceleration, load balancing, as well as a host of other acceleration engines enabling application in a large variety of market segments. The XLP Processor family is a third-generation architectural enhancement to RMI's industry leading Multi-core XLR Processor® family. The XLP832 is fabricated using 40-nm technology and offers processor core frequencies from 500 MHz to greater than 2.0 GHz, providing a 3x performance/watt improvement over its XLR® predecessor. The XLP832 is software backward-compatible with the XLR and XLS® Processor families. The XLP832 Processor contains a wide array of networking interfaces (Interlaken, XAUI, SGMII) and system interfaces (including of PCI Express 2.0, an LA-1 Interlaken for TCAM, and two USB 2.0 host/client ports.

The XLP Processor is targeted at expanding the overall opportunity for RMI’s Multi-core Multi-threaded product offerings and enables a broad set of application specific features for customer use in security appliances, L4-L7 switching, storage networking, 3G/4G wireless, and small business networks, as well as several new market opportunities for RMI. Early development work with the world’s leading storage, networking, telecom, wireless and enterprise customers has been in place for over 2 years. RMI will sample multiple members of the XLP Processor family in the fourth quarter of this year.

Unmatched Scalability
The XLP832 scales to support quad-chip configurations with greater than 100Gbps throughput capabilities. The XLP Processor family will also include single core offerings that provide new performance per watt leadership solutions in lower-end applications such as broadband access gateways, wireless LAN access points, secure wireless routers, entry level NAS and NVR devices and Office Automation. RMI will also offer various XLP family members employing 2 to 6 EC4400 Cores to provide optimal solutions for mid-range applications such as wireless base stations, Enterprise security appliances, cloud computing, data center offload, etc. At the higher end, RMI’s 8 core XLP832 offering provides a single chip 40Gbps class solution with quad chip configurations scaling to support application solutions requiring more than 100 Gbps of throughput. This product offering will establish RMI as the only company on the planet capable of providing optimized system solutions that scale over three orders of magnitude; from less than 100Mbps to greater than 100Gbps.
