Dirac HD Sound? technology leverages 32-bit processing capabilities of CEVA market-leading audio DSP
Technology to be demonstrated at Mobile World Congress 2012

CEVA, Inc. (NASDAQ: CEVA); (LSE: CVA), the leading licensor of silicon intellectual property (SIP) platform solutions and DSP cores, and Dirac Research AB, a specialist in high-end audio technology, have announced that the companies have partnered to deliver advanced speaker correction capabilities for the 32-bit CEVA-TeakLite-III DSP, targeting mobile, home and automotive applications. These Dirac technologies extend CEVA?s leadership in low-power, high-performance audio platforms, and this solution is already in use by a top-tier audio chip vendor.

The Dirac HD Sound? solution is a mixed-phase speaker correction technology that optimizes a sound system?s transient reproduction for optimal performance and clarity. This software offering has now been fully optimized for the native 32-bit processing capabilities of the CEVA-TeakLite-III architecture, ensuring a cost-efficient low power and low system overhead solution, even within constrained systems. The two companies will demonstrate the combined solution at the upcoming Mobile World Congress in Barcelona, February 27 ? March 1, 2012, in CEVA?s booth (Hall 1, Stand 1F 33).

?CEVA is recognized for its advanced 32-bit audio DSPs, with numerous production design wins and broad market adoption. Their audio-tuned architecture and advanced instruction set provide a cost-effective and high-quality platform on which to implement the Dirac HD Sound technology. Using CEVA?s comprehensive software development tools and their excellent support, we were able to produce and demonstrate a fully optimized version of Dirac HD Sound in a matter of days,? said Mathias Johansson, CEO at Dirac.

?We are pleased to add Dirac?s premium quality audio post-processing capability to the ecosystem of our CEVA-TeakLite-III DSP, supporting more than 90 voice and audio codecs, and pre- and post-processing functions,? said Eran Briman, Vice President of marketing at CEVA,? Dirac?s approach enables a high quality post-processing solution for developers of audio ICs in an easy to deploy, cost-efficient manner.?

The Dirac HD Sound technology has been proven across a range of high-end audio applications in the consumer, cinema, professional and automotive markets. The technology enhances many audio and voice aspects, including voice correction, stereo image correction, bass correction, listening fatigue minimization, and tonal and transient correction.

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 scenarios, such as multi-stream audio playback with various post-processing functions for an enhanced audio experience. The DSP-based solution includes a configurable cached memory subsystem, a comprehensive set of optimized HD audio codecs, and a complete software development kit, including software development tools, prototype boards, test chips, system drivers and RTOS.
