HelloVoice(TM) Software Reference Design on Display at the 2003 ESC Conference
CAMBRIDGE, England and SAN JOSE, Calif., April 22 /PRNewswire-FirstCall/
-- ARM [(LSE: ARM); (Nasdaq: ARMHY)], the industry's leading provider of
16/32-bit embedded RISC processor solutions, and HelloSoft, Inc., a leading
provider of communications software IP, today announced at the Embedded
Systems Conference (ESC), San Francisco, that HelloSoft has developed a
complete VoIP phone software suite fully optimized for a single ARM926EJ-S(TM)
core. The software reference design implementing the phone suite, including
voice codec and protocols running on the Linux operating system, is being
demonstrated at ARM Booth No. 1902 at ESC.
The traditional VoIP system architecture uses two processors to implement
all software elements of an IP phone. The two processors -- a RISC
microprocessor and a DSP processor -- are discrete components requiring
separate memories, peripherals and buses, thus increasing cost for the end
product. In addition, the two processors often require separate code
development environments: one for the OS and protocols running on the RISC
core, and one for the codecs and other DSP components running on the DSP
processor. This adds to the complexity of software development and can
significantly affect the product's time-to-market.
The ARM and HelloSoft solution implements all VoIP functions including
codecs, line echo cancellers, telephony components and telephony signalling
stack on a single ARM926EJ-S core running the Linux OS. The optimized
solution is powerful enough to implement two channels of voice for VoIP
phones, wireless IP phones, residential gateways, integrated access devices
and other VoIP-enabled devices.
"The combination of a DSP-enhanced core such as the ARM926EJ-S processor,
and HelloSoft's VoIP phone suite optimized to the ARM9E(TM) family, represents
a major step forward in assisting OEMs and ODMs in significantly reducing the
cost and complexity of developing VoIP phone systems," said Denise Kerstein,
networking segment manager, ARM. "This solution will also benefit other types
of products which will integrate VoIP as a service, such as cellular phones,
integrated access devices, residential gateways, consumer devices and even
automotive infotainment systems."
"ARM and HelloSoft are working together to drive the next inflection point
in the VoIP market," said Krishna Yarlagadda, CEO and president, HelloSoft.
"The effect of this ultra-low-cost VoIP solution from our two companies cannot
be underestimated in regards to its effect on enabling the market."
The HelloVoice(TM) software reference design is a complete solution
including G.711, G.726 and G.729AB vocoders, G.168-2000 Line Echo Canceller,
Voice Activity Detection, Comfort Noise Generation, Jitter Buffer, Packet Loss
Concealment, DTMF Tone Detection and Generation, SIP/RTP/RTCP Call Signaling
and Control and multichannel system-level framework.
The ARM926EJ-S core, which HelloSoft is utilizing, is fully synthesizable
and features a DSP-enhanced, Jazelle(R) technology-enhanced 32-bit RISC CPU,
flexible size instruction and data caches, tightly coupled memory (TCM)
interfaces and a memory management unit (MMU). It also provides separate
instruction and data AMBA(TM) bus-compliant AHB interfaces particularly
suitable for multi-layer AHB-based systems. The ARM926EJ-S core implements
the ARMv5TEJ instruction set and includes an enhanced 16- x 32-bit multiplier,
capable of single-cycle MAC operations.
Availability
Voice components are available this quarter from HelloSoft. The
Integrator(TM) platform, used for the reference design, and the ARM926EJ-S
core are available now from ARM.
