12/18/2003 - Cypress Semiconductor Corp. (NYSE:CY) announced the availability of cycle-accurate C models of its AyamaTM 20000 LA-1 attach Network Search Engines (NSEs). In addition to being recognized as the industry’s highest-performance NSE at 266-million searches per second (MSPS), the Ayama 20000 NSE also provides advanced support for the Intel® IXP2400/2800/2850 network processors units (NPUs). The Ayama 20000 NSE software models are interoperable with Intel NPUs as well as with the Intel software development kit (SDK) version 3.1.
Cypress's Ayama 20000 NSE uses the LA-1 interface to seamlessly connect to multiple network NPUs. The Ayama 20000 NSE’s cycle-accurate C-model plugs seamlessly into the foreign-object model (FOM) interface of Intel’s NPU transactor models. This allows software engineers to perform early prototyping and software development, even before the availability of hardware.
“Cypress is actively involved in defining and promoting standards-based packet-processing solutions,” said Geoff Charubin, managing director of Marketing and Applications for Cypress’s Data Communications Division. “Our comprehensive search solutions, which include the highest-performance NSEs on the market, extensive software support and easy-to-use development kits for use across multiple NPUs, also provide a significant time-to-market advantage to our customers.”
The software interoperability between the Ayama 20000 NSE and Intel IXP2xxx NPUs is demonstrated using a 5-tuple lookup in a typical Layer 3 IPv4 switch reference application. The Ayama 20000 NSE C-model ships as part of Cypress's Cynapse Software Platform that includes table managers, device drivers, reference applications and diagnostics.
Cypress Semiconductor, as a member of the Intel Communication Alliance (ICA), recently announced support for the Intel PICMG3.x AdvancedTCATM development environment. Cypress successfully demonstrated interoperability with Intel IXP2xxx NPUs at the Intel Development Forum 2003 and also at the Network Processor Conference West 2003, both held in San Jose, California.

Cypress's Network Search Engines
The Ayama 10000 family of NSEs maintains the Cypress lead in the commercial TCAM market by extending the density and speed of the NSE70000 family: density options of 4-Mbit, 9-Mbit and 18-Mbit with speeds up to 266 MSPS. In addition, the Ayama 10000 family addresses system’s power and latency concerns with differentiated features such as Mini-KeyTM power management and Soft PriorityTM table management. Mini-Key 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 table management enables dynamic prioritization of entries for longest prefix match (LPM) in Layer 3 forwarding applications, eliminating the latency associated with routing table updates.
Building on the Ayama 10000 family, the Ayama 20000 NSE is a high-performance TCAM-based network search engine that seamlessly connects to the Network Processing Forum (NPF) approved LA-1 interface-based commercial NPUs. The Ayama 20000 NSE has several key features such as two LA-1 ports for ingress/egress database sharing, automatic address generation for associated data, support for aging, and patent-pending dynamic power management. The Ayama 20000 NSE is available in 9-Mbit and 18-Mbit densities; at 266-million searches per second (MSPS) it is the highest-performance LA-1 based NSE in the market.
In addition to TCAM-based solutions, Cypress is the only vendor to also offer an Algorithmic SRAM-based forwarding search engine. The SahasraTM 50000 NSE is a family of algorithmic search engines optimized for large forwarding tables in applications such as virtual router forwarding (VRF) and virtual private network (VPNs) that need greater than one-million table entries. The Sahasra NSE family can achieve 250 MSPS, at a fraction of the power and cost of existing TCAM-based search solutions.
Cypress’s comprehensive NSE portfolio has been adopted by leading routers, L2/3 switches, CMTS, DSLAMs and storage area networks manufacturers.
