Tensilica Introduces the Smallest, Lowest Power DSP IP Core For Always-Listening Voice Trigger and Voice Recognition

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. See the press release.
