LAS VEGAS--(BUSINESS WIRE)--May 7, 2001

New Integrated Interface Data Plane Solution Accelerates Development

and Time-to-Market for Networking OEMs

NetLogic Microsystems, Inc., the leader in search engine technology, and Applied Micro Circuits Corporation's switching and network processing group (AMCC) (Nasdaq:AMCC) today announced at Networld+InterOp the industry's first fully integrated search engine and network processor solution, enhancing wire-speed packet processing. NetLogic's OPIX family of search engines and classification processors can now seamlessly interface to AMCC network processors without the use of programmable logic or an ASIC interface. The new integrated solution dramatically reduces development time and cost for equipment designers, thus accelerating time-to-market for next-generation networking equipment.

NetLogic's new "glue-less" solution integrates the company's Multi-Processor Search Interface (MPSI) technology into its network search engines and packet classification and forwarding database processors. The embedded search interface allows multiple AMCC network processors to interface to NetLogic's search engines and data plane processors without the need of additional hardware, such as an FPGA or ASIC. The integrated platform complements one or multiple AMCC network processors in delivering OC-48 wire-speeds by seamlessly offloading the computation-intensive task of searching packet classification and packet forwarding databases.

NetLogic's OPIX family complements and extends AMCC's own product offerings. AMCC separately announced today its own "External Search Machine" as an initial product to satisfy its customers' immediate needs, while noting that NetLogic would offer further innovation in search engine and classification processor offerings going forward.

"AMCC turned to NetLogic, the leader in data plane classification processors, to further extend our solutions for rich QoS functionality at OC-48c line rates," stated Andy Gottlieb, vice president of marketing for AMCC's switching and network processing group. "NetLogic's products offer the largest databases and highest performance. They are the only company to offer the Zero Table Management(TM) architecture that complements AMCC's own techniques for simplifying database table management."

"NetLogic clearly recognizes AMCC's leadership position in the NPU marketplace," said TJ Mueller, vice president of marketing at NetLogic Microsystems. "It makes sense that the industry's first seamless interface between a network processor and the essential database has been developed by two industry leaders. Together, we are providing our mutual customers with all the benefits of an integrated solution -- shortened development time, reduced costs, and the highest level of flexibility for optimizing policy-based networking."

The combined solution guarantees Quality of Service (QoS) and other complex policy-based networking requirements. With the ability to support wire-speeds of OC-48, this design solution is ideal for applications including Voice over IP (VoIP), streaming data, virtual private networks (VPNs), policy enforcement, Internet security, IPv4/IPv6 routing, load balancing, firewalling and Web caching.

NetLogic's NSE3128GLM and CFP3128GLM, the first two members of the "glue-less" devices, can be interfaced with AMCC's nP7250, nP3400, nP7120 as well as future AMCC network processors. Most noteworthy is that NetLogic's products work glue-lessly with AMCC's recently announced nP7250 OC-48c network processors. Future plans will include additional NetLogic search engines and processors with AMCC's next-generation nPcore(TM)-based solutions.

Product Availability

Sampling for the NetLogic NSE3128GLM and the CFP3128GLM, both of which include additional optional features like aging, policing and learning, is scheduled for August 2001. Volume production is scheduled for Q4 2001.
