Re-Architecting Edge Devices for the Internet of Things

This project aims to enable a new class of intelligent, ultra-low-power computer systems for the Internet of Things. Future IoT applications will demand intelligence at the edge to avoid expensive and insecure communication with the cloud. These applications run on very low power budgets either due to extend battery life or because systems harvest energy from their environment. Unfortunately, conventional, performance-oriented systems are too inefficient to run sophisticated computation (e.g., machine learning) on the device itself.

We are revisiting system design across the stack, from runtime systems to compilers to ISA to microarchitecture, to dramatically improve energy-efficiency and enable sophisticated on-device computation. Our Sonic software system enables energy-efficient machine learning while tolerating frequency power failures (ASPLOS’19), and our programmable MANIC architecture eliminates most of the wasted energy in a conventional microcontroller through a new execution model called vector-dataflow execution (MICRO’19). This project is building real prototypes, as shown above in our energy-harvesting demo for Sonic, and shown in the image below for our upcoming tape-out of the MANIC architecture in Intel 22nm FFL.

This project is a collaboration with Brandon Lucia.
