Ultra Low Power Computing in the IoT Era

Speaker: Prof. Rakesh Kumar
Affiliation: University of Illinois at Urbana Champaign

Abstract: Wearables, sensors, and Internet of Things (IoT) arguably represent the next frontier of computing. They will be characterized by extremely low power and area requirements. In our recent research, we asked the question: are there opportunities for power and area reduction that are unique to these emerging computing platforms. We answered the question in the affirmative and developed several techniques that appear to be very effective. In this talk, I will focus one such technique–symbolic hardware-software co-analysis–that is applicable over a wide class of applications. Through a novel symbolic execution-based approach, we can determine for a given application the gates in the hardware that the application is guaranteed to not touch. This information can then be used to determine application-specific Vmin, determine application-specific peak power, and, build bespoke processors customized to a given application. If time permits, I will also discuss how architectural ideas such bit serial processors and k-hot pipelining may become promising for the IoT applications.
