nP7250
OC-48c Network Processor (1xOC-48 / 2xGE)
General Description
The nP7250 represents the third generation in packet and cell processing
technology from the original pioneering vendor of software-programmable
network processors. The nP7250 offers Layer 2, 3, 4, and above packet and
cell processing at wire speed for multiservice cell/packet switching and
routing systems in both clear channel (OC-48c) and multi-channel (OC-48,
4xOC-12, 2xGE, 16xOC-3) modes. The device provides two identical frame
interfaces
fabric or traffic manager
level 3), Flex Bus 3, Dual RGGI, and ViX
The nP7250 combines gluelessly with AMCC
framer, MAC, and search coprocessor products to provide complete data-
plane solutions or can be used easily with an OEM
any or all of these areas.
AMCC’s nPsoft ™ Development Environment speeds creation of vendor
differentiating features by combining the fundamentally simplified, nPcore
based programming model of all AMCC NPUs with advanced development
tools, rich application reference libraries, real hardware
systems, and the services of the industry
processor-based system design staff.

Benefits
Third-Generation Silicon
Along with the nPX5700 10 Gbps traffic manager and nPX5800 20
switch fabric, the nP7250 represents our third generation of packet and cell
processing, queuing, scheduling, and switching technology, starting with
MMC Networks, the original pioneer of software-programmable network
processors, which merged with AMCC in 2000. With switching and network
processing solutions in designs by over 100 different customers, including
every “ Tier -1 ” networking equipment vendor, AMCC
matured through years of invaluable real
most field -proven network processor technology. And focused purely on the
networking and communications industry, our vast experience has
produced the industry
based design services team to support our high-performance products.
Flexible, Efficient nPcore
Each AMCC network processor is built around our patented nPcore
technology, which offers a unique combination of performance and
flexibility. Using hardware multi
powerful on-chip coprocessors to implement key atomic, single-instruction
operations, the nP7250 achieves extreme efficiency
low-power cores. And yet the nPcore model still preserves complete
programming flexibility, allowing the developer to arbitrarily program his
algorithms without restrictions from fixed stages or elements. AMCC NPUs
thus offer the flexibility of more general
efficiency of more fixed-function NPUs.
Fundamentally Simplified Multi-Processor Programming Model
With multiple multi-threaded nPcores, the nP7250 can process many
packets or cells simultaneously, but with AMCC
completion ” programming model, each packet or cell executes in a single
thread on a single core. In this way, the software developer simply creates
a single program without being forced to break up and load-balance
algorithms across multiple
based on more general-purpose processor core architectures. Future
migrations are simpler, too, since once an algorithm is developed it never
has to be re-subdivided across a different number of cores in a next-
generation device.
Glueless Framer Interface Support
The nP7250 has dual symmetric frame interfaces configurable in the
following formats: UTOPIA L3, POS-PHY L3, Flex Bus 3, RGGI or ViX-V3. The
OC-48 port can also be used as streams of channelized 4xOC-12, 16xOC-3
for UTOPIA L3, POS-PHY L3 and Flex Bus 3. The nP7250 is fully standards-
compliant with the OIF
Packet and Cell Processing
The nP7250 ’s flexibility to process both cells and packets sets it apart from
almost all other NPU offerings today. Each port can be configured to
process cells, packets, or both simultaneously.
Embedded Network Coprocessors
Multiple on -chip coprocessors further enhance the nP7250

parallel to the nPcores. Insert/delete data, compute and attach CRC32, and
attach packet header components can all be performed by a single
instruction.

both improved and more deterministic performance.
