VeriSilicon Launches G.722.2
TMCnet Contributing Editor
These days, companies are constantly looking to enhance the quality of VoIP communications. VeriSilicon is certainly no exception.
An ASIC design foundry and semiconductor IP provider focusing on design and manufacturing services for customers worldwide, VeriSilicon has added 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.
This has been a busy summer for VeriSilicon. Last month, the company announced the acquisition of the assets of the ZSP Digital Signal Processor unit of LSI Logic Corporation. Under terms of an asset purchase agreement, VeriSilicon acquired certain assets related to ZSP licensable cores, development tools, standard products and software and associated issued and pending patents. The majority of the ZSP unit workforce, including engineers, software developers, sales and marketing, customer service and support representatives joined VeriSilicon.
