Mueller-BBM Active Noise Control and Sound Design Now Optimized on Cadence Tensilica HiFi Audio/Voice Processors for Automotive Applications

SAN JOSE, Calif. and PLANEGG, Germany, Oct. 22, 2014 — (PRNewswire) — Cadence Design Systems, Inc. (NASDAQ: CDNS), a leader in global electronic design innovation, and Müller-BBM Active Sound Technology, a global leader in automotive Active Noise Control (ANC) and Active Sound Design (ASD) technology, today announced that an optimized port of Müller-BBM's m|klang® ANC and ASD software is now available on the Cadence® Tensilica® HiFi Audio/Voice digital signal processing (DSP) family. This is the first time m|klang ANC and ASD software has been ported to a licensable intellectual property (IP) DSP core.

m|klang ANC and ASD are successfully used by leading global OEMs to reduce in-vehicle noise, and to create unique vehicle sound and driving experiences of their production vehicles. Having the technology available on HiFi processors now allows integrating these premium audio system features into mainstream automotive head units, making them available to a broad range of cars and customers. The first vehicles to utilize m|klang on HiFi processors are expected at dealerships later this year.

"We targeted the Cadence HiFi DSP cores for our first IP core port because they are the most widely used audio IP cores in the automotive system-on-chip market," said Dr. Rolf Schirmacher, managing director of Müller-BBM Active Sound Technology. "By providing an optimized port of our software on the HiFi DSP cores, we can offer automotive OEMs and Tier 1 suppliers an easy integration of our m|klang technology throughout a broad range of different semiconductor manufacturers. This helps automotive OEMs create a consistent, unique automotive sound experience independent of actual audio component content of a specific vehicle."

"We're seeing strong demand from our HiFi licensees and their Tier 1 and OEM customers for active noise cancellation and sound enhancement technologies to improve the in-car driving experience," said Larry Przywara, product line group director of audio/voice IP at Cadence. "Müller-BBM's m|klang technology is an ideal match, providing these features as a complete solution fully optimized on our HiFi DSP cores."

The Tensilica HiFi Audio/Voice DSP core family features more than 125 software packages that have been ported to the HiFi architecture by Cadence and more than 55 partners. For more information on the HiFi DSP family, visit
