Tensilica Introduces the Smallest, Lowest Power DSP IP Core for Always-Listening Voice Trigger and Voice Recognition
SANTA CLARA, CA, Jan 03, 2013 (MARKETWIRE via COMTEX) --
Tensilica(R), Inc. today introduced the HiFi Mini DSP (digital
signal processor) core, the smallest, lowest power DSP IP core
supporting always listening voice trigger and speech command modes.
Optimized specifically for the smallest area and lowest power in
smartphones, tablets, appliances, and automotive applications, the
HiFi Mini DSP IP core enables a hands-free experience. Tensilica is
working with Sensory and other software partners that will provide
the voice-activation, speech command recognition, voice
pre-processing and noise reduction products optimized on the HiFi
Mini DSP.
"Voice activation and speech command are essential ingredients in
making devices much more user friendly, and we see that the market
for devices utilizing this technology will explode in the years
ahead," stated Michael Morgan, mobile devices senior analyst with ABI
Research. "A number of companies are working on the software side,
but it's also important to have a very low power DSP to run that
software so battery life is not meaningfully impacted. Tensilica's
HiFi Mini will help drive this market."
Tensilica optimized the HiFi Mini DSP core to be as small and power
efficient as possible for voice trigger and voice recognition in two
major ways. First, the core uses compact 40-bit encoding, which
significantly improves code size. Second, Tensilica added
efficient16-bit instructions that are optimized for voice and audio
codecs. The result is a post-route core that's only 0.039 mm2 in 28
nm HPL.
"Power is the single most important factor in enabling always-on
listening capability in mobile devices. Using Sensory's Truly
Handsfree voice control technology, HiFi Mini is able to achieve less
than 88 uW of power for the core in 28 nm HPL, achieving both the
lowest power consumption and uncompromising accuracy for speech
recognition," stated Larry Przywara, Tensilica's senior director of
mobile multimedia. "The combination of ultra-low power and small area
makes HiFi Mini an attractive addition to mobile as well as other
consumer electronics. And as voice control emerges as the natural
interface, we expect it will become more ubiquitous as it migrates to
automotive, consumer appliances and potentially industrial control."
The HiFi Mini DSP IP core will be available in March 2013. Tensilica
will demonstrate Sensory's Truly Handsfree voice trigger and speech
command products on HiFi Mini at the Consumer Electronics Show in
booth MP25060, January 8-11, 2013 in Las Vegas, NV USA.
