Cypress's Leading Network Search Engines to Support LA-1 Network Processor Interface

9/24/2002 - Cypress Semiconductor announced support for the Look-Aside (LA-1) interface recently ratified by the Network Processing Forum (NPF). The LA-1 interface is designed to provide direct connectivity from the Network Processing Unit (NPU) to Network Search Engines (NSE) and coprocessors. Cypress's Ayama 20000 family of NSE products has been designed to incorporate the newly adopted standard. By supporting the LA-1 interface, Cypress will provide a seamless interface to the industry's top commercial NPUs, including those from Intel, AMCC and IBM.

The Ayama 20000 NSE family will provide multiple densities from 128K IP entries (4.5 Mb) to 512K IP entries (18 Mbit). All members of this family will have the capability to seamlessly connect to multiple NPUs using the LA-1 interface. Additionally, the Ayama 20000 family will offer innovative features such as Mini-KeyTM power management which can reduce power consumption by up to 70%; Soft PriorityTM for effortless table management, thereby drastically reducing table-update latencies; and Multi-SearchTM, which can effectively double search performance.

The QDRTM SRAM co-development team, of which Cypress is a founding member, formulated elements of the Quad Data RateTM (QDRTM) interface that were incorporated into the LA-1 interface and adopted by the leading NPU vendors. QDR SRAM is a high-performance communications memory standard for network switches, routers, and other communications applications. Since leading memory vendors such as Cypress participated in the LA-1 specification development, users can be confident that the LA-1 specification meets real-world needs.

"As a leading team member of the QDR SRAM co-development team, Cypress is well qualified to port LA-1 to its NSE and NCP products," said Rob Raghavan, senior marketing manager of Cypress's Data Communications Division. "By offering the LA-1 interface in a broad range of our products enabling very fast, wire-speed packet processing we can provide seamless connectivity to all of the leading commercial network processors in the market, thus saving our mutual customers the step of purchasing and designing additional glue logic."

Cypress's Network Search Engines and Coprocessors
Cypress offers the industry's widest selection of network search solutions, including network search engines and network coprocessors. Cypress's packet processing solutions are ideal for use in routers, switches, and other high-performance networking infrastructure systems.

Cypress's broad array of products includes the current 32K-, 64K-, 128K-, 256K- IP entry NSE70000 family. The current devices are configurable from 34- to 288-bit data widths to support Layer 2 to Layer 7 applications. These NSEs can search the network database at up to 100 MSPS, enabling processing at wirespeeds greater than 2.5 Gbps.

Cypress's NCP80192 network coprocessor manages the interaction between existing industry standard network processors and Cypress NSEs. The NCP80192 coprocessor accelerates packet processing by offloading tasks from network processors and facilitating database management. The coprocessor's programmable 32-channel descriptor ring supports multiple contexts, each of which can be programmed independently.
