Tensilica Inc. is getting ready to release the HiFi Mini DSP core, the smallest, lowest power DSP IP core supporting
always listening voice trigger and speech command modes.
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.
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
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
