HiFi audio dsp first ip core approved for Dolby MS10 multistream decoder

Tensilica has announced that it is the first intellectual property (ip) company with an audio core for SoC designs approved for using the Dolby MS10 multistream decoder.

The decoder is a multi-format audio decoding technology, that supports Dolby Digital Plus and Dolby Pulse in a single package for next generation hdtvs, set top boxes and digital media players.

The Dolby MS10 multistream decoder is critical to next generation designs because it enables viewers to receive content not only from traditional broadcast and operator sources, but also from the Internet, usb devices, game consoles, and pcs. This array of source content uses a corresponding array of audio codecs, which Dolby has consolidated into MS10.

The Dolby MS10 decodes Dolby Digital Plus, Dolby Digital, Dolby Pulse, HE AAC, and all AAC bitstreams. For compatibility with the worldwide base of existing home theatre systems, it enables the decoded audio streams to be transcoded into a Dolby Digital audio output bitstream for multichannel surround, stereo, and mono sound.

Tensilica's HiFi 2 and HiFi EP audio dsps are fully programmable processor cores optimised for audio applications, with a library of over 60 of the most popular audio software packages. Other Dolby certified packages include: Dolby Digital Decode, Dolby Digital Creator Encode, Dolby Digital Compatible Output Encode, Dolby Digital Plus 5.1 and 7.1-channel Decode, Dolby True HD Decode and Dolby Pro Logic IIx.
