Dolby goes Mobile

September 13, 2011 // By Phil Ling
DSP IP provider, Ceva, claims to be the first company in the semiconductor industry to offer a Dolby approved DSP core implementation of Dolby Mobile. Based on its CEVA-TeakLite-III DSP, the implementation of the third generation Dolby Mobile technology, including support of Dolby Digital Plus for mobile, targets designers of mobile audio processors incorporating Dolby’s latest mobile audio enhancements.

Dolby Mobile is designed to give consumers a rich, full-impact audio experience on portable devices. Designed for easy, flexible implementation, Dolby Mobile allows device makers to enable a multitude of stunning audio settings, including full 5.1-channel HD audio, mobile surround and natural bass.

Many of these features require DSP-intensive, audio post-processing techniques to be performed in real-time on the mobile device, and call for a high-performance DSP-based audio processor architecture for efficient implementation. The CEVA-TeakLite-III DSP based implementation consumes up to 5X less power than today’s CPU-based alternatives, delivering critical power savings and extending battery life for Dolby Mobile-enabled devices, such as smartphones and tablets.

"The availability of our Dolby Mobile technology on the CEVA-TeakLite-III DSP constitutes a compelling solution for customers designing advanced mobile audio processors,” said Patrick Flanagan, Director of Product Marketing, Mobile Ecosystem, Dolby Laboratories. “CEVA’s low power DSP architecture enables Dolby Mobile to efficiently deliver the advanced audio that consumers demand, without sacrificing battery-life of the target device.”

The provision of the third generation of the Dolby Mobile was achieved using actual CEVA-TeakLite-III silicon, providing CEVA customers with a silicon-proven hardware and software solution that aims to streamline the overall design cycle for advanced mobile audio processors. The DSP solution includes a configurable cached memory subsystem, a comprehensive set of optimized HD audio codecs, and complete software development kit, including software development tools, prototype boards, test chips, system drivers and RTOS.
