Tensilica has announced that it is the first audio IP (intellectual property) core supplier to be awarded DTS Broadcast and DTS DMP (Digital Media Player) certification.

The certification, achieved using fully optimised software implementation on Tensilica’s Hi-Fi 2 and Hi-Fi EP Audio DSP (digital signal processor) IP cores, provides developers of SOCs (system on chips) with a solution that reduces the time to market for new, fully compliant designs.

Tensilica was also the first IP core supplier to be certified for DTS-HD Master Audio in September of 2009.

The Hi-Fi Audio DSP is designed into consumer devices including HDTVs, smartphones, home-entertainment receivers, digital set-top boxes (STBs), digital/HD radios and Blu-ray Disc players.

Even in the most challenging Blu-ray Disc use cases, where DTS-HD Master Audio is processed by a single Tensilica core, there remains room to spare for significant audio pre/post processing.

Additionally, there’s room to spare in audio subsystems with significant memory latency.

Tensilica is the only IP core vendor to be certified by DTS based upon highly accurate, pipeline-modelled instruction set simulation models of the Hi-Fi Audio DSPs, it claims.

This certification methodology allows Tensilica licensees, who subsequently submit their completed SOC designs to DTS for chip-level certification, to shave weeks or months off the certification cycle.

The DMP package allows decoding of popular DTS content by creating a stereo mix-down and provides a DTS 5.1 digital bit-stream to external home theatre systems.

The DTS broadcast package incorporates all the functionality of the DMP package and extends this to target DTS 5.1 core content delivered over traditional cable, satellite, terrestrial and IP networks.

It also supports infrastructures such as video-on-demand, IPTV and managed networks.
