Speech Title: Event-Driven System Architecture for Ultra Low Power AIoT Sensors
Abstract: Artificial Intelligence-of-Things (AIoT) devices differ from the IoT counterpart that not only they sense, store, transmit data but also analyze and act on data, i.e. they perform tasks similar to what a person could do. For the ubiquitous deployment of sensors in AIoT, power consumption of each sensor should be made as low as possible for extended operation hours. The traditional signal processing flow relies on Nyquist rate to digitize input signal, which generates redundant samples for sparse inputs in many AIoT applications and increases power consumption for the AI engine. Different from Nyquist sampling scheme, the event-driven system generates samples only if a predefined event occurs, i.e. the power consumption tracks the input activities. The amount of data generated in an event-driven system is intrinsically compressed, leading to significant savings in power. This keynote talk will introduce several low power features of an even-driven system, and demonstrate how to achieve orders of magnitude reduction in power consumption.
