Tensilica announced today that it will soon launch a HiFi 2 audio DSP-based DRM decoder that allows designers to easily integrate the HiFi 2 engine into the SOC design. The decoder is based on Dolby source and has been validated by Dolby Laboratories. Digital radio system designers need only one processor core (Tensilica HiFi 2 Audio DSP) to support audio decoding standards in digital radio receivers around the world. The Tensilica HiFi 2 Audio DSP supports four terrestrial and satellite digital radio standards including DAB, DAB+, HD Radio and XM Radio.

DRM can provide FM sound at frequencies below 30 MHz (this band is commonly used in AM broadcasts today) and can be used for long-distance signal propagation. The advantage of DRM is that it uses digital audio compression technology instead of amplitude modulation technology to transmit multiple signals in a limited frequency band and maintain high sound quality. DRM has been certified by the IEC (International Electrotechnical Commission) and the ITU (International Telecommunication Union) has approved its use in most countries of the world. It is also being applied to the ITU for use in North and South America and the Pacific.
Larry Przywara, director of mobile multimedia marketing at Tensilica, said: "In the current economic climate, chip makers will increase the cost of producing different radio products for different regions of the market, while SOC chips with Tensilica HiFi 2 audio DSPs are embedded. Compatible with all digital radio standards worldwide. We have successfully partnered with Dolby on HE AAC and its derivatives (including DAB+ and T-DMB), so we still choose to work with Dolby on the DRM standard. The customer has been authorized by the HiFi 2 DRM decoder.
Toni Fiedler, senior manager of Dolby Laboratories, said: "Indian and Russian radio agencies have actively adopted digital radio and DRM standards because they cover a wider range of frequencies below 30 MHz. Based on the positive of these countries Driven by the rapid development of the digital radio market, the timely launch of the Tensilica HiFi 2 audio DSP has driven the development of integrated multi-standard digital radio SOC chips, reducing the cost of DRM receivers. The HiFi 2 audio engine provides a customer A complete audio solution certified and certified by Dolby Laboratories."
The HiFi 2 audio DSP is based on the Tensilica programmable Xtensa ® processor, giving chip designers a hardware platform that can be used in a variety of audio standards. Tensilica and its partners and customers have successfully ported codec algorithms for more than 50 audio formats on HiFi 2 audio DSPs, allowing designers to choose the algorithms they need. With the evolution of the market and the emergence of new standards, new algorithms can be quickly ported to HiFi 2 audio DSPs. Tensilica's HiFi 2 audio DSP has been widely used by five of the world's top ten semiconductor manufacturers.
