| Product Brief NP3705 2.5-Gbps Network Processor with Integrated Traffic Manager Benefits * High integration for Significant form factor, cost, and power savings * Hardware-based Traffic Manager for guaranteed performance * Software compatibility with previous generation nP devices: nP37x0, nP34xx, nP7250 * Simple programming model for rapid development and quick time-to-market Overview The NP3705 family of integrated network processors is a derivative of the nP3700 family that expands AMCC's nP5TM technology to lower speed, cost-sensitive access applications. 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 finegrained control of subscriber traffic, without impacting the ability to perform complex protocol inter-working at media speeds. The NP3705 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 for quickest time-to-market. of feature-rich, wire-speed, Layer 2-7 applications by combining the simplified nPcoreTM 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 NP3705 allows easy API access to onchip coprocessors for complex tasks, customer differentiating features can be created faster and with fewer lines of code. Features Supports 2.5-Gbps Traffic * nP5 Technology * Mix and match Gigabit Ethernet, POS, and ATM traffic * Standalone or as a line card in a larger system Proven nPcore Architecture * 1 nPcore at 700 MHz optimized for network processing * Single-stage single-image programming model * High-speed RLDRAM-II or FCRAM-II memory interface for payload and context storage * Per-flow metering and statistics for millions of flows Industry Leading Integration and Performance The NP3705 is a 2.5-Gbps network processing and traffic management solution. In addition to highperformance packet processing and fine-grained traffic management, the NP3705 includes specialized coprocessors that perform classification, policing, and coherent database management for unparalleled line-rate performance. The devices are offered in different speed grades to provide a range of performance and cost options tuned to the application.

AMCC provides extensive offerings for the programmable nP37xx Integrated Network Processors, including both rich off-the-shelf application software and a complete development environment for extending this application base if desired. * The MISSION application software includes ready-to-use Multi-Service Switching software - ATM UNI/NNI, Inverse Multiplexing over ATM (IMA), Multi-Link Frame Relay (ML-FR), Multi-Link PPP (ML-PPP), Frame Relay and FR to ATM Interworking (FR IWF), MPLS Martini encapsulation - as well as OEM customer-extensible libraries for the hardware-resident aspects of higher layer applications such as IPv4 and IPv6 routing, and Layer 2 packet switching. MISSIONTM -- Multi-Service Internetworking Solution The NP3705, combined with AMCC's Amur (S1215) channelized framer and ATM/HDLC/GFP processor extend AMCC's MISSION multi-service offering to applications up to OC-12/STM-4 rates. This solution enables the development of single multiprotocol solutions in place of multiple single-protocol solutions. The MISSION architecture provides equipment vendors with solutions that enable their customers to save on both capital and operational expenditures (CapEx/OpEx). 36 RL/FC-DRAMII 2 x FE Policy Engine LINE INTERFACES SPU XSC Hash Engine Scatch Pad SPI-3 + GE 2xGE Memory Access Unit SPI-3 12xFE 2xUL2/PL2 FE/GE MACs Statistics Engine Traffic Manager Queuing Scheduling QDR SRAM / LA-1 nPcore @ 700 Mhz 24 Tasks Soft TM JTAG 18 Line Interfaces (CSM) HOST CPU 16 SPI4.2 Packet Transform Engine (PTE) DEBUG FCN / QAB Figure 3.
