Features
Product Overview
The MSP7150-PGI multi-service processor is a carrier grade
gateway SoC for EPON/GPON/EoC/WiMAX/IP PBX applications and
a line interface solution for multi-service residential gateways
(RGs). The chipset addresses carrier multi-service requirements
with superior performance, advanced QoS capabilities, and robust
voice processing achieved with a standard, open programming
model.
The MSP7150-PGI chipset is part of PMC-Sierra's 7100 Series of
multi-service processors, which now also includes the MSP7150.
The MSP7150-PGI extends the range of the 7100 Series by
including higher performance and enhanced interfaces.
The 7100 Series enables Telco and ISP visions for the digital home
to be turned into reality. This newest breed of RG processor
ensures concurrent single-core functionality for voice, video, and
data services resulting in service performance guarantees. The
MSP7150-PGI's superior packet processing and QoS performance
address planned and evolving use cases. As well, the MSP7150-PGI
has the processing power to support all EPON/GPON carrier
service models including LAN traffic and headroom to support
application processing.
The MSP7150-PGI's high performance multi-threaded (MT) 7100
Series core delivers dynamic multifunction guarantees for the
flexible allocation of resources. Combined with three 10/100/1000
GE MACs, a DDR1/2 memory interface, and dual USB 2.0 interfaces,
this powerful RG engine plays a central role for the delivery
of IP services.
The MSP7150-PGI chipset supports PMC EPON and GPON drivers,
and third party drivers including WiFi, SLIC/SLAC, MoCA and HPNA
for faster time-to-market.
The MSP7150-PGI includes a Linux software development kit and
reference application software including OpenWRT and oSIP. System Processor

Benefits
Exceptional simultaneous processing behaviors are essential for
triple play and the evolution to true multi-service deployments.
PMC-Sierra's RG solution enables complex traffic management,
routing, bridging, and firewall tasks concurrently with the ability
to support processing guarantees for voice, video, and data
services. These simultaneous processing capabilities ensure critical
quality of experience (QoE) for all broadband service deployments.
- Multi-function Core
- Dynamic reassignment of processing cycles between diverse
functions of the multi-service digital home with cycle
guarantees for robust QoE
- Processing Power
- The 600 MHz MT 7100 Core achieves industry-leading processing
power
- Provides essential headroom to address requirements for
evolving services, service bandwidth, and digital home
infrastructure: stronger management/control, interworking of
HAN technologies for end-to-end QoS, and gateway application
processing
- Multi-service Networking
- Greater packet processing permits advanced QoS features for
robust service delivery, for high service bandwidth and
guarantees for service growth
- Robust Voice Processing
- VoIP Terminal Adapter functionality is guaranteed,
independent of all other processing and traffic conditions
- Centralized processing of voice enables resources (when not
required for voice functions) to be dynamically allocated to
other functions without influence from software
|
- 'Programmer-friendly' Programming Model
- Leverages standard tools and a large software ecosystem with
best of breed components support
- Linux-based software stack
- Open 7100 Series programming model
- MaxMT Networking FastPath
- Significantly improves network throughput performance
- Easily customized to meet the growing complexity of today's
gateway requirements
- Gigabit Throughput
- The MSP7100 Core provides exceptionally fast networking
performance to leverage the full potential of next generation
access networks and ultra-high-speed home networking
technologies

Software
The MSP7150-PGI is supported by a Linux software development
kit (7100 Series RG SDK). The SDK enables designers to quickly and
easily build high-performance, feature-rich gateways.
The SDK includes a voice processing module (VPM) VoIP firmware
suite.
The MSP7150-PGI and SDK are supported by standard tools from
industry leading vendors as well as by GNU development tools
(compiler, debugger, EJTAG support, etc.). PMC leverages open
source SMP Linux and OpenWRT based software to provide
flexible and easy customizations to meet the growing complexity
of today's residential gateway requirements.
