Ensigma, Ltd., Develops Enhanced Variable Rate Codec Software On DSP Group's OakDSPCore®

CHEPSTOW, United Kingdom, Oct. 21 -- Ensigma announced today the completion of its Enhanced Variable Rate Codec (EVRC) IS-127 implementation for DSP Group's OakDSPCore®. The EVRC Codec is used in the IS-95 CDMA system offering enhanced speech quality compared to the original 8k QCELP vocoder. EVRC is also to be used in the Japanese W-CDMA and U.S. CDMA-2000 systems. Clifford Parris head of the coding group at Ensigma, said ``We are the first company to be offering an EVRC solution'' The company said the excellent development tools offer a faster time to market compared to rival DSPs.

``We are pleased to have Ensigma as a developer and software provider for our OakDSPCore,'' said Gideon Wertheizer, vice president of corporate marketing for DSP Group. ``Ensigma's EVRC solution allows OEMs to bring CDMA systems to the market quickly,'' Wertheizer continued.
