The nP3710 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 nP3710 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 nP3710 is an Ethernet-focused version of
the nP3700 5-Gbps network processor. In
addition to high-performance packet
processing and fine-grained traffic
management, the nP3710 includes four
embedded Ethernet MACs, specialized
coprocessors that perform classification,
policing, and coherent database management
for unparalleled line-rate performance. The
nP3710 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 nP3710 allows easy API access to
on-chip coprocessors for complex tasks,
customer differentiating features can be created
faster and with fewer lines of code.
