Cypress NSE Shipments Pass 1.5 Million Unit Mark; Broad Portfolio Enables Widespread Adoption of NSEs for Switches, Routers and Networking Infrastructure Systems.

Business Editors

SAN JOSE, Calif.--(BUSINESS WIRE)--June 10, 2003

Cypress Semiconductor Corporation (NYSE:CY) today announced it has shipped over one and a half million network search engines (NSEs). In Internet routers, switches and other networking infrastructure systems, NSEs accelerate packet processing by offloading search functions from the ASIC or network processor. The milestone demonstrates Cypress's leadership in network search solutions, including TCAM-based NSEs and network coprocessors.

As Internet usage, data communications line rates, and traffic complexity increase, transmission bottlenecks are emerging, particularly in the packet processing section of the networking linecard. In order to solve this packet processing bottleneck and the resulting search problem, designers are moving away from simple, software-based solutions in favor of intelligent hardware-based search architectures customized to address the requirements of specific applications.

"Cypress NSEs are an important contributor to wirespeed performance, policy-based routing, and IP-address scalability in Foundry Networks' Enterprise and Metro service provider systems," said Karl Triebes, Chief Technology Officer at Foundry Networks. "The advanced feature set of Cypress's NSEs contributes to Foundry's ability to offer highly scalable platforms that its more than 5,800 customers worldwide can leverage to meet their revenue and business objectives. Cypress's evolving packet search solutions correspond with the development of Foundry's advanced JetCore(TM) and Terathon(TM) ASIC-based systems in emerging market areas such as Gigabit over Copper and 10G Ethernet."

"Shipping over 1.5 million NSEs to our customers confirms customer adoption of our approach to solving the search problem and has established Cypress as the market leader in the search space," said Geoff Charubin, Senior Director of Marketing for Cypress's Data Communications Division. "The success of our NSE70000 family over the last four years has enabled us to gain insight into the top networking vendors' current and future needs. In order to meet the demands of next-generation networks, Cypress has extended its broad portfolio of deterministic, deep-packet search solutions that continue to set the standard for packet-processing innovation."

Cypress's Network Search Engines

Cypress's broad array of products includes the current NSE70000 family, custom versions of NSEs for Cisco, and the NCP80192 coprocessor. The NSE7000 family, launched in 1999, includes densities of 1M, 2M, 4M, and 9M to meet the need of increasing table sizes.

The Ayama(TM) 10000 family of devices will maintain the Cypress lead by extending the density and speed of the NSE70000 family with differentiated features such as Mini-Key(TM) power management and Soft Priority(TM) table management. MiniKey(TM) power management reduces power by engaging only the portion of the NSE array that contains entries of interest, thereby reducing power consumption by as much as 70%. Soft Priority(TM) table management enables dynamic prioritization of entries for longest prefix match (LPM) in Layer 2/3 forwarding applications, eliminating the latency associated with routing table updates.

The Ayama 20000 devices build upon all the features of Ayama 10000 in addition to providing the LA-1 interface, a standard adopted by the NPF. The Ayama 20000 NSE devices will provide a glue-less connection to Intel's IXP2400/2800 network processors and AMCC's next-generation network processors that support the LA-1 standard.
