Cadence Announces Fourth Generation Tensilica HiFi DSP Architecture

New audio solution enables emerging multi-channel object-based audio standards

SAN JOSE, Calif., Jan. 06, 2015 – 

Cadence Design Systems, Inc. (NASDAQ: CDNS), today announced the Cadence® Tensilica® HiFi 4 audio/voice digital signal processor (DSP) intellectual property (IP) core for system-on-chip (SoC) designs, which offers the industry's highest performance licensable digital signal processing (DSP) core for 32-bit audio/voice processing. This fourth generation HiFi architecture enables emerging multi-channel object-based audio standards and offers 2X the performance versus the HiFi 3 DSP, making it ideal for DSP intensive applications including digital TV, set-top box (STB), Blu-ray Disc and automotive infotainment.

With emerging object-based audio standards, individual sounds become objects that can be placed anywhere in a room. Instead of being mixed at a recording studio, these sounds are mixed on the fly at each location where they are played back. The object-based audio system calculates where the sound should emanate so that it appears in roughly the same space, no matter where speakers are located. This provides a more natural and immersive sound experience, and requires much more DSP processing power. Instead of having to use multiple DSPs to accomplish this, designers can now get the DSP power they need from one core - the HiFi 4 DSP.

Cadence's Tensilica HiFi 4 DSP is a highly optimized audio/voice processor geared for efficient execution of audio and voice codecs and pre- and post-processing modules as well as other demanding DSP functions in areas such as wireless communications. Its key features include:

PARTNER QUOTES

"Audio processing requirements continue to increase, particularly as we move to object-oriented audio in the home," stated John Couling, senior vice president at Dolby Laboratories. "Cadence's HiFi 4 provides the processing power required to help enable a better, more immersive and personalized experience for users of high-end home entertainment systems who want to take advantage of the sound improvements inherent in object-oriented audio."

"DTS:X™ is the next-generation audio codec from DTS that leverages object-based audio to give listeners new, immersive and interactive experiences," stated Joanna Skrdlant, vice president, solutions licensing at DTS. "The HiFi 4 DSP with quad 32-bit MACs is an ideal processor to support the demanding needs of object-based audio decoding such as DTS:X processing to provide a compelling consumer audio experience."

"Consumers will soon be able to experience immersive sound and personalize their listening experience while listening to TVs and new media devices receiving the new MPEG-H Audio standard promoted by the MPEG-H Audio Alliance," said Robert Bleidt, Division General Manager, Fraunhofer USA Digital Media Technologies. "Immersive sound may involve 10 or 12 channels of audio, with additional audio elements such as dialogue, alternate languages, home- or away-team commentary, or even driver's or athlete's microphones requiring more channels to be transmitted for high-profile broadcasts, increasing the decoder workload. Thus, DSPs such as the Cadence Tensilica HiFi 4 DSP will play an important role in efficiently implementing the new standard in tomorrow's consumer electronics."

"Our Maxx technologies utilize Waves' 20+ years of professional audio expertise and innovation to dramatically improve sound quality on a broad range of devices from TVs and PCs to mobile and automotive infotainment," said Tomer Elbaz, EVP and general manager of Waves Consumer Division. "The Cadence Tensilica HiFi 4 DSP is ideal for efficiently running our all our technologies in the highest performance mode to provide the best user experience."

About Cadence Design Systems, Inc.

Cadence Design Systems is a leading global EDA company. Cadence customers use our software, hardware, and services to overcome a range of technical and economic hurdles.

Our technologies help customers create mobile devices with longer battery life. Designers of ICs for game consoles and other consumer electronics speed their products to market using our hardware simulators to run software on a virtual chip long before the actual chip exists. We bridge the traditional gap between chip designers and fabrication facilities, so that manufacturing challenges can be addressed early in the design stage. And our custom IC design platform enables designers to harmonize the divergent worlds of analog and digital design to create some of the most advanced mixed-signal system on chip (SoC) designs. These are just a few of the many essential Cadence solutions that drive the success of leading IC and electronic systems companies.
