Industry's fastest low-power network search engine

Cypress Semiconductor has announced the industry's first 128K network search engine (NSE) with 1.5V core and 1.8V I/O capacity.

Cypress Semiconductor has announced the industry's first 128K network search engine (NSE) with 1.5V core and 1.8V I/O capacity.

Target applications include broadband switches and routers supporting multiple datarates at OC-48 and beyond.

The CYNSE70128 enables high datarates with performance as fast as 100 million searches per second.

The CYNSE70128 can operate with 3.3, 2.5 and 1.8V devices, allowing designers to incorporate it into existing designs as well as systems using next-generation, low-voltage ASICs or network processors.

The device's ternary nature allows for the optimal processing of complex routing protocols.

It also has variable entry widths to allow for multi-layer processing; its double-datarate (DDR) feature enables it to operate without performance degradation at multiple entry widths.

"The CYNSE70128 provides an ideal feature set - including very high performance and low power for network systems - and adds to our existing portfolio of 32K and 64K NSEs", said Geoff Charubin, director of marketing for Cypress's Data Communications Division.

"It also extends Cypress's reach across the entire network linecard.

Cypress now has a full portfolio of port, packet processing and backplane solutions for network designers.

No other company can provide this range of products and services".

All Cypress's NSEs can interface through the CYNCP80192 NCP with all current network processors.

The CYNCP80192 offers an SSRAM interface, offloads table and pipeline management from the processor, and offers a silicon-optimised ASSP solution to customers.

The NCP can interface to multiple CYNSE70128s, as well as the other NSE devices from Cypress, including the CYNSE70032 and the CYNSE70064.

These devices have all the features of the CYNSE70128, and they can operate as fast as 83 million searches per second.

Cypress's NSEs can facilitate both centralised and decentralised architectures.

The family includes 32K-, 64K- and 128K-entry devices, with 256K-entry devices currently in development.

They are configurable from 34 to 288bit data widths to support Layer 2 to Layer 7 applications.

These NSEs can search the network database at up to 100 million searches per second for wire speeds of OC-48/STM-16, OC-192/STM-64 and OC-768/STM-256.

Cypress's network coprocessors manage the interaction between industry standard network processors and Cypress NSEs.

These coprocessors accelerate packet processing by offloading tasks from network processors and facilitating database management.

The coprocessor's programmable 32-channel descriptor ring supports multiple contexts, which can be programmed independently.

In quantities of 10,000, the CYNSE70128 is priced as low as $129.

All are packaged in a 388-ball BGA.

Cypress offers a reference design kit (RDK) that provides the necessary simulation and diagnostic tools for engineers to design and debug their systems quickly.

The CYNSE-DEVKIT01 offers various routing schemes to simulate different routing environments.

The RDK is available through Cypress sales representatives.
