Keywords:single-core  HD audio  home entertainment  DSP 

CEVA has developed a single-core solution that is claimed to be the most compact and power-efficient solution available for HD audio integration into home entertainment and consumer ICs. The configurable and programmable platform—called CEVA-HD-Audio—is designed to address the most demanding consumer/home entertainment audio needs, such as Blu-Ray DVDs, DTVs, set-top boxes and other home A/V devices.

Based on the IP vendor's 32-bit TeakLite-III DSP core running at speeds of up to 550 MHz, the solution offers a complete set of optimised audio codecs, including memory overlay support that takes advantage of a generic DMA controller. As a result, according to the company, CEVA-HD-Audio meets the stringent requirements of advanced audio systems, without compromising die size or power consumption, while also allowing developers of low-cost audio solutions to reduce the BOM by supporting slow DDR memories.

The platform includes a configurable memory sub-system; a large set of audio codecs optimised for the DSP in a typical audio system; and a complete software development kit. The audio codecs support from two channels up to 7.1 channels with various bit-rates, and formats including MP3, AAC-LC, HE-AAC, WMA, AC-3, RealAudio, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD MA, DTS-HD HR and others.

The CEVA-HD-Audio solution is currently available for licensing.
