SAN JOSE, Calif., March 31, 2015—Cadence Design Systems, Inc. (NASDAQ:
CDNS) and Accusonus today announced that the Accusonus Focus-MDR and Focus-DNR
speech enhancement software has been ported to and optimized for the Cadence® Tensilica®
HiFi Audio/Voice digital signal processors (DSPs). The Accusonus software provides the first
integrated solution for reverberation and noise supression, ideal for challenging indoor
acoustic environments.

Focus-MDR and Focus-DNR technology, visit

The Focus-MDR and Focus-DNR speech enhancement products offer a single- or
multi-microphone approach to suppression of reverberation, as well as direct and ambient
noise. Because they are flexible to handle various microphone configurations, the products are
ideal for smartphones, tablets, and laptops.

Tensilica HiFi Audio/Voice DSPs are the most widely used and licensable audio/voice
DSP intellectual property (IP) family, with support for over 140 proven audio/voice software
packages and over 70 partners.

“Our software provides speech quality improvement for far-field use cases, when
there’s a longer distance between the user and the device. System designers can take
advantage of our patent-pending reverberation and ambient noise suppression solution that
utilizes multi-microphone configurations and integrates principles of DSP, room acoustics and
psychoacoustics,” stated Elias Kokkinis, CTO, Accusonus. “Porting to the Tensilica HiFi
Audio/Voice DSP made sense because of high customer demand and its highly optimized 
architecture geared towards more efficient execution of audio and voice codecs and pre- and
post-processing modules.”

“Accusonus has a unique and compelling solution for the problem of room reflections
and reverberation that improves the voice experience quality of mobile devices,” said Larry
Przywara, group director of Audio/Voice IP Marketing at Cadence.
“By collaborating,
Accusonus and Cadence can offer our mutual customers the Focus speech enhancement
software optimized for the HiFi DSP architecture, plus the advantage of a significantly lower
frequency enabling lower power compared to other architectures.”
