network processing

• Single-stage single-image

programming model

• High-speed RLDRAM-II memory

interfaces for payload and context

storage

• Per-flow metering and statistics for

millions of flows

Integrated Traffic Manager

• Per-flow queuing and scheduling

• Sophisticated, fine-grained sched-

uling algorithms

Standards-Compliant

• OIF SPI-3, OIF SPI-4 Phase 2

The nP3740 integrated network processor is a derivative

of the nP3700 family, the first network processor family to

incorporate the latest nP

5

™ technology. Developed over several generations of traffic management

and network processor products, nP

5

unites the flexibility of the industry’s highest performance

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.
