5-Gbps Network Processor with Integrated Traffic Manager
Overview
The nP3700 family of integrated network
processors from AMCC are the first to
incorporate the latest nP^5TM technology.
Developed over several generations of
traffic management and network
processor products, nP⁵ 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 nP3700 family 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 nP3700 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 nP3700 includes
specialized coprocessors that perform
classification, policing, and coherent
database management for unparalleled
line-rate performance. The nP3700
supports high-performance memory
interfaces such as RLDRAM II, DDR
DRAM, and DDR 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^TM development
environment speeds the development,
debugging, and delivery of feature-rich,
wire-speed, Layer 2-7 applications by
combining the simplified nPcore^TM
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
nP3700 allows easy API access to
on-chip coprocessors for complex tasks,
customer differentiating features can be
created faster and with fewer lines of
code.
