Cadence Drives Release of Alternative EVS Codec Implementation in 3GPP

New codec enables up to 1.6X performance improvement and better
battery life for mobile communications applications

SAN JOSE, Calif.–(BUSINESS WIRE)–Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced that it
initiated and drove the standardization within 3GPP of an alternative
fixed-point Enhanced Voice Services (EVS) codec reference implementation
using updated basic operators. 3GPP, a global initiative that provides
complete system specifications for cellular telecommunications network
technologies, has adopted and released the new codec, which enables more
efficient processing and improves battery life by leveraging modern DSP
architectures with 64-bit accumulators, single instruction, multiple
data (SIMD) and very long instruction word (VLIW) technologies. As part
of this effort, Cadence also updated the basic operators incorporated in
the underlying ITU Software Tools Library (STL2018), which serves as the
foundation upon which 3GPP reference codecs are built. Next-generation
codecs can now utilize these new basic operators for faster time to
market and better energy efficiency.

Cadence developed the instruction set architecture for its Tensilica®
HiFi 3z DSP in parallel with the development of these updated basic
operators and the alternative EVS codec, resulting in the HiFi 3z DSP
featuring an extremely efficient pairing of hardware and software. As a
result, the HiFi 3z DSP offers a 1.6X improvement in million cycles per
second (MCPS) as compared to the HiFi 3 DSP running the original EVS
codec in Super Wideband mode—enabling lower power and longer battery
life. Utilizing the new codec, the HiFi 3 DSP offers a 1.2X improvement
in MCPS in Super Wideband mode.

“For more than two years, Cadence has taken a leadership role in 3GPP to
drive the development, adoption and release of an alternative version of
the EVS codec that takes advantage of modern DSP architectures,” stated
Larry Przywara, group director of marketing, Tensilica audio/voice IP at
Cadence. “Our smartphone-OEM and mobile semiconductor customers have
already licensed this codec for their upcoming HiFi 3z DSP-based
products. Cadence thanks 3GPP Working Group SA4 for their efforts to
standardize this alternative version.”

The alternative EVS codec reference code is available
for download
from the 3GPP website.
