Aspinity has developed a revolutionary new technology that enables the implementation
of ultra-low power, data-efficient, always-on sensing solutions at the edge. In today’s
always-on sensing solutions, the intelligence is distributed between the edge and the cloud,
collecting data from the environment and digitizing it for local analysis of potential wake
words before sending it on to the cloud for final verification. This methodology wastes
significant power digitizing, analyzing, and wirelessly transmitting irrelevant data.
For lower-bandwidth applications such as fitness trackers and motion detectors, this low
level of edge intelligence can meet the power budget of battery-operated devices by duty cycling
or turning on and off the data gathering system without impacting the application. However, for
higher-bandwidth applications such as voice and vibration, where all sound input is critical and
must be processed, duty cycling reduces the accuracy of the application.
Aspinity’s unique, ultra-low power Reconfigurable Analog/Mixed-Signal Integrated Circuit
(RAMP IC) technology brings a higher level of intelligence to the edge by changing the paradigm
from a "digitize" first architecture, where all data is digitized/analyzed, to an "analyze"
first architecture, where sensor data is only digitized for higher level analysis when an event
signature (voice, vibration, etc.) has been detected. For high bandwidth, random and sporadic
applications such as always-on voice wake-up, the RAMP IC brings a higher level of intelligence
to the edge of battery-operated voice-first devices, reducing the power required by 10x by
eliminating the digitization and processing of the 80% of sound that is not voice.
