Cadence Offers Industry's First Licensable Audio DSP IP Supporting Dolby Digital Plus With DS1

SAN JOSE, CA -- (Marketwired) -- Oct 10, 2013 -- Cadence Design Systems, Inc. (NASDAQ: CDNS)


  • Tensilica HiFi Audio/Voice DSP brings clearer voice and richer sound to small speaker systems, from mobile devices to flat-panel TVs
  • Dolby DS1 Mobile enhances audio quality in mobile devices and small speaker systems

Cadence Design Systems, Inc. (NASDAQ: CDNS), a leader in global electronic design innovation, today announced that its Tensilica® HiFi Audio/Voice DSP is the first intellectual property (IP) core to offer a certified decoder for Dolby® DS1 for Dolby Digital Plus™ audio streams. Available now, this decoder targets audio applications in mobile devices such as handsets and tablets as well as any infotainment system with small speakers, like ultra-slim flat-panel TVs. Dolby DS1 for Digital Plus is optimized to provide mobile users with home theater-inspired sound quality by enabling a distortion-free audio/voice boost and also by compensating for unintelligible dialogue, extreme volume variation, and deficiencies inherent in the small speakers and low-power amplifiers on most mobile devices.

"Device makers worldwide are looking for ways to differentiate and meet consumer demands for mobile entertainment," said John Couling, senior vice president, E-Media, Dolby. "The Tensilica HiFi Audio/Voice DSP is a proven platform that enables the most premium audio experiences today with Dolby technologies."

"Better audio and video user experiences drive customer buying decisions on mobile devices, so the Dolby DS1 enhancements are highly valued by OEM companies designing handsets, tablets and any small-speaker infotainment systems," said Jack Guedj, corporate vice president, IP Group at Cadence. "Dolby Digital Plus with DS1 makes significant optimizations for dialogue clarity, surround virtualization and volume leveling, which will deliver end-product differentiation."

As part of the broader Tensilica DPU (dataplane processing unit) product offering, Cadence's Tensilica HiFi Audio/Voice DSP is the most widely used licensable audio/voice DSP family, with support for over 100 proven audio/voice software packages. More than 55 companies have licensed the HiFi DSP family, and they have shipped over 200 million HiFi DSP cores in smartphones, tablets, computers, digital televisions, home entertainment systems and other devices.
