3rd Generation Traffic Stream Processor – TSP3

Programmable Traffic Management and

Protocol Interworking Processor for Access

Applications

High performance network processing optimized

for access & enterprise applications

The M27481 is built on the third generation traffic stream

processor architecture (TSP3) and is targeted for access

and enterprise applications requiring programmable traffic

management and Layer 2 interworking functions. Layer 2

interworking functions include, but are not limited to,

Ethernet-to-ATM bridging, IP-to-ATM, cell and packet

switching, and AAL2.

Device highlights include integrated “universal-link” and

Ethernet interfaces, internal SRAM for low latency context

storage, hierarchical traffic management & multicast

support and a Layer 2, 3 & 4 aware multi-protocol flow

classification engine. The M27481 system dissipates no

more than 6.25 W of power (including external SDRAM). The

M27481 TSP3 architecture provides the foundation for

unprecedented performance-to-price network processing

while satisfying the system cost and power sensitivity

associated with next-generation access and enterprise

equipment.

The M27481 programmability can be leveraged to support

a broad set of applications that allows a common hardware

design to be used interchangeably for edge aggregation

applications (e.g. fast/gigabit Ethernet, xDSL, PON, voice,

IMA). M27481 can also be used to simplify intrasystem

connectivity, providing an aggregation method for a large

number of low speed PHY’s while supporting proprietary

data formats and headers over a variety of electrical

interfaces. Devices within the TSP3 family are all software

compatible promoting design reuse across applications,

port speeds (from NxT1/E1 to 2.5 Gbps) and vendor platforms.

packet and cell traffic management and protocol inter-

working for over 2 Gbps/2.5 Mpps total throughput on up

to 1,280 traffic streams. For larger numbers of streams, up

to 64K, the device supports over 625 Mpbs/750Kpps total

throughput. In order to shorten product development,

Mindspeed Technologies™ offers a system-tested software

suite, including PortMakerIII and BroadbandMaker applica-

tions. Development tools, source code licenses and

consulting services are also available.
