CEVA-TeakLite-III Becomes Industry's First DSP Core To Offer Optimized Skype SILK Super Wideband Speech Codec





MOUNTAIN VIEW, Calif., April 3, 2012 /PRNewswire/ -- CEVA, Inc. (NASDAQ: CEVA); (LSE: CVA), the leading licensor of silicon intellectual property (SIP) platform solutions and DSP cores, today announced the availability of the industry's first implementation of the popular Skype™ SILK™ super wideband speech codec on a DSP core. Optimized for the 32-bit CEVA-TeakLite-III family of audio DSPs and forward compatible with future versions of the widely-used CEVA-TeakLite DSP architecture, CEVA's implementation of the SILK codec delivers a high quality, cost-efficient voice communications solution for both mobile and digital home applications, with significant power savings compared to alternative solutions.

The SILK super wideband 24 KHz codec, developed and used by Skype, enables high quality voice communications through PC, mobile device and Smart TV applications. The computational complexity of wideband codecs, including the SILK codec, requires native 32-bit data processing rather than traditional 16 or 24-bit DSPs in order to achieve the optimal performance. The CEVA-TeakLite-III DSP is the only mass market proven native 32-bit DSP IP core that has been specifically architected to address these stringent wideband codec performance requirements.

For the many CEVA customers and partners already deploying the widely-deployed CEVA-TeakLite-III DSP for voice/audio processing in their mobile and digital home SoCs, this implementation of SILK enables them to easily embed this super wideband speech codec for Skype support into their existing designs.

"We are pleased to add support for this highly popular voice codec to the more than 90 other voice and audio codecs in the CEVA-TeakLite ecosystem. Skype has gained worldwide penetration as a reliable and widely available voice communications application that can be used in a variety of end products. The combination of our native 32-bit processing with the low power capabilities of the CEVA-TeakLite-III DSP will benefit product developers who wish to efficiently incorporate Skype support into their devices," said Moshe Sheier, director of product marketing at CEVA.

The CEVA-TeakLite-III is a native 32-bit, high performance audio DSP core, used in mobile application processors, audio CODEC chips, baseband processor chips and home entertainment main SoCs, to handle, among other tasks, advanced audio and voice scenarios, such as multi-microphone noise suppression for clearer voice communication and multi-stream audio playback with various post-processing functions. The DSP-based solution includes a configurable cached memory subsystem, a comprehensive set of optimized audio and voice codecs, and complete software development kit, including software development tools, prototype boards, test chips, system drivers and RTOS.
