MSP2015
Multi-Service Processor
Released
MSP for VoIP Gateways and Phones, Wired and Wireless
GENERAL
The MSP2015 belongs to a full family of
Multi-Service Processors designed to
meet the performance, QoS and security
needs of communications equipment
used within the customer premise. The
MSP2015 is an ideal solution for VoIP
Gateways and wireless IP Phones. As
shown below, it includes a MIPS CPU,
three 10/100 Ethernet MACs, TDM
interface, and a PCI interface.
The MSP2015 provides a new level of
price performance for VoIP Gateways
and wireless IP phones. Because the
MSP2015 eliminates the need for a
separate processor, voice processing
DSP, and multiple Ethernet MACs,
systems can now be built with fewer
chips at a very affordable price point.
The MSP2015 has a unique systems
architecture that provides wire-speed
performance. This architecture includes
a powerful MIPS CPU, a 4.25 Gbps bus,
16KB Scratchpad, and intelligent context
aware DMA engines. Together, this
results in an extremely cost effective
VoIP solution. Integration of 802.11a, b,
and g wireless LANs is easily facilitated
through the PCI interface.
To reduce time-to-market, PMC-Sierra
offers comprehensive support for the
MSP2015, including evaluation boards,
software, application engineering
support, training, and documentation
that together accelerate the product
development process. In addition, the
MSP2015 supports Linux, VxWorks, or
custom operating systems.
