A Taiwan-based software vendor said it is doing its part to speed the
deliver of voice over Internet Protocol
E-Soft has released a new reference design for the Intel
XScale IXP-425 chipset, the company said Friday. The platform
is part of its IAD (Integrated Access Device) software. The company said its
reference design could help equipment developers create high-performance
combined router, firewall/NAT
devices. Currently E-Soft said it has contracted the reference design out to
five unnamed vendors working on their own VoIP devices.
The design supports devices including
those based on SIP
telephone network (PSTN) analog phones. The IAD also maintains IP Ethernet
connections, Wi-Fi for creation of a wireless hotspot, and RJ-11 sockets for
connecting PSTN phones
The IAD design also supports both the VxWorks and embedded Linux platform
architectures and allows for advanced DSP support such as echo cancellation,
automatic gain control, voice activity detector, jitter elimination, and
packet loss concealment.
E-Soft said it developed its IAD designs with the help of
Radvision’s SIP/H.323 IP Phone and IAD developer
toolkit. E-Soft, which said it would be marketing the package to its
customers, said the platform allows for crossover of the transport and call
feature layers, as well as the gateway and phone applications for voice over
IP. Prices were not disclosed.
“E-IAD is already finding huge success as a flexible development
platform, thanks to the Radvision technology, for reducing the time it takes
OEMs or ODMs to develop VoIP-enabled devices such as VoIP AP, VoIP gateways,
and other IP-based communication devices,” Michael Su, vice president of
E-Soft, said in a statement.
Su said choosing Intel’s XScale as the processor architecture was a
no-brainer. The ARM-based RISC core clocks up to 533MHz with 64k of cache.
But it is also important to embedded product developers because Intel knit
together several components on the chip including a SDRAM controller, two
high-speed serial ports, two 10/100Mbit Ethernet ports, a UTOPIA interface
for ATM / xDSL, PCI bus, host USB, and even an encryption accelerator.
The
chip can be used in a variety of applications, such as high-end residential
gateways, small to medium enterprise (SME) routers, switches, security
devices, mini-DSLAMs (Digital Subscriber Line Access Multiplexers), xDSL
line cards, wireless access points, industrial control systems and networked
printers.
