VeriSilicon Launches GSM-AMR-WB (G.722.2) Wideband Codec on ZSP(R) for 3G Wireless and VoIP Applications

G.722.2 Provides Higher Voice Communication Quality Than PSTN for Enterprise VoIP and Emerging IMS Systems

    SANTA CLARA, Calif., Aug. 7 /Xinhua-PRNewswire/ --
VeriSilicon, a leading world class ASIC design foundry and
semiconductor IP provider focusing on design and
manufacturing services for customers worldwide, today
announced the addition of GSM-AMR-WB (G.722.2) wideband
codec to its Z.Voice portfolio of VoIP solutions. 
GSM-AMR-WB standardized by 3GPP for mobile phone
applications is also available under ITU as G.722.2 for
wideband IP phone applications.  G.722.2 is the compression
standard for voice sampled at 16KHz, covering the audio
frequencies from 50Hz to 7KHz and improving the
intelligibility of speech compared to narrow band codecs
such as G.711 and G.729.

    G.722.2 will enhance quality for all voice
communications over IP and wireless networks by improving
the intelligibility of speech on fricative sounds such as
"s" and "f" compared to narrow band
speech.  The implementation of G.722.2 on the ZSP cores
families takes one-third of the performance needed by any
RISC processors at significantly lower power consumption. 
The addition of wideband AEC for speakerphone applications
makes ZSP the only viable embedded processor family for
battery operated wideband voice applications.

    "By combining its rich portfolio of ZSP IP cores,
VoIP software, ASIC design and turnkey services,
VeriSilicon is enabling silicon and system solutions for
emerging applications such as wideband IP phones, dual mode
VoWiFi and Instant Messaging based phones," said
Federico Arcelli, Corporate VP of WW Marketing at
VeriSilicon.  "System and fabless chip companies can
work with us to shorten their time to market in the
development of innovative, cost effective products for VoIP
applications.
