Technology

The nP3740 integrated network processor is a derivative

of the nP3700 family, the first network processor family to

incorporate the latest nP

and network processor products, nP

network processing nPcore with the most widely deployed and mature traffic management

technology. This unique combination enables developers to deliver extremely fine-grained control of

subscriber traffic, without impacting the ability to perform complex protocol inter-working at media

speeds. The nP3740 is designed from the ground up to provide software compatibility with the earlier

generations of AMCC Network Processors. The single-stage programming model dramatically

simplifies software development and troubleshooting and enables quickest time-to-market.

Industry Leading Integration and

Performance

The nP3740 is a 5-Gbps network processing and

traffic management solution – the highest

performance integrated solution in the industry.

In addition to high-performance packet

processing and fine-grained traffic

management, the nP3740 includes specialized

coprocessors that perform classification,

policing, and coherent database management

for unparalleled line-rate performance. The

nP3740 supports high-performance memory

interfaces such as RLDRAM II and QDR-II SRAM.

The devices are offered in different speed

grades to provide a range of performance and

cost options tuned to the application.

Rapid Application Development

AMCC's nPsoft™ development environment

speeds the development, debugging, and

delivery of feature-rich, wire-speed, Layer 2-7

applications by combining the simplified

nPcore™ programming model of all AMCC NPUs

with open, layered nPsoft Services, advanced

development tools, rich reference application

libraries, and both simulation and real

hardware-based development systems.

Because the nP3740 allows easy API access to

on-chip coprocessors for complex tasks,

customer differentiating features can be created

faster and with fewer lines of code.
