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, 2006 -- 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.

Availability

The G.722.2 Codec is available now for licensing as part of VeriSilicon's Z.Voice software solution.
