™-based nPcore™ technology
The nP3454 is a successor to AMCC’s highly-adopted
nP3404 Network Processor with Integrated Traffic
Manager device. The nP3454 is pin-compatible with the nP3404, but with twice the performance.
The nP3454 is implemented using industry leading nP
devices) with enhanced network processing and traffic management.
The increased performance, efficiency, headroom, flexibility, and integration afforded by this proven
technology enables customers to deliver more features at lower cost, power, and size than ever before.
High-density Ethernet interfaces combined with superior programmability provide the best
combination for enabling value-added Ethernet Services for Wireline/WiFi Access and Metro Ethernet
Networks.
Industry Leading Performance and
Flexibility
The nP3454 network processing unit consists of
two low-power network processing nPcores™
that are based on proven nP
These nPcores, along with specialized Network
Service Accelerators such as Policy Engine,
Special Purpose Policing Unit, Packet Transform
Engine, and Statistics Engine, offer unparalleled
performance at line rate.
The superior programmability and flexibility of
these cores enable flexible support for existing
and future networking protocols. All of the line
interfaces on this device are standards-
compliant maximizing inter-operability and
flexibility.

Value Added Services
The traffic management unit of the nP3454 is
based on the proven Per-Stream Queuing™ and
Scheduling architecture allowing guaranteed
and measurable services. The nP3454 traffic
manager’s four classes of service (CoS) enable
layered services. The enhanced multicast
scheme and programmable memory
management provide increased flexibility in
traffic management.
Software Compatibility
With its “run-to-completion” single-image
programming model and nPkernel software
infrastructure, the nP3454 is software-
compatible with the nP
provides enormous leverage for customers in
reusing software from prior generations of
design and achieving quick time-to-market.
