Running on the OS level does drain power. Even using the baseband or apps processors can be inefficient. This is why Sensory has ported to processors such as Cirrus Logic, Conexant, DSPG, Realtek, Texas Instruments, Wolfson, and all of the leading IP platforms (ARM, CEVA, Tensilica, Verisilicon, etc.), and many more. Our chip and IP partners are reporting power consumption as low as 1.7mA. That includes the microphone and preamp circuit, and it can go even lower by using a sound detection front end to turn off processing in quiet conditions. Tensilica has even introduced the HiFi Mini IP core targeting Sensory’s TrulyHandsfree approach for companies that want to use always on technology without extra bells and whistles.
