Tensilica – HiFi audio / voice DSP and software codecs selected for DTVs

Tensilica has announced that Hisense, China, is using its HiFi Audio/Voice DSP (digital signal processor) to do all of the audio decoding and post processing in its new SOCs (system on chips) for DTV (digital televisions). Tensilica’s HiFi Audio/Voice DSP is the most popular audio IP core on the market, with the lowest power and largest library of ported software codecs, says the company.

“For product differentiation, we decided to design our own DTV chips and we needed an audio DSP that was compatible with all of the possible worldwide audio standards, and would offer the highest level of sound fidelity with the most efficient power and area,” said Liu Weidong, general manager of HiView, Hisense’s IC design subsidiary. “Tensilica’s HiFi Audio is the leading IP core and has the largest library of audio codecs and audio/voice pre- and post-processing software ported and optimized for it. It is making our design efforts much easier.”

Larry Przywara, Tensilica’s senior director of multimedia marketing, said: “Hisense is gaining market share around the world with its cost-effective DTV designs. Hisense has continuously enhanced both its audio and video quality and we are pleased they have selected Tensilica to achieve the highest level of sound fidelity. We look forward to their first TVs with our audio DSPs hitting the market next year.”

Tensilica’s HiFi Audio DSPs have been selected by leading DTV manufacturers around the world and they are the leading licensable audio DSP IP cores, licensed by over 50 customers including half of the top 20 semiconductor manufacturers and many leading system OEMs. The HiFi Audio DSPs support over 100 audio and voice codecs with very efficient processing at low power and they are part of Tensilica’s growing line of DPUs (dataplane processors) that efficiently do the challenging, compute-intensive tasks in SOC designs, says the company.
