Abstract - IOT microcontrollers are complex constrained SOCs with analog peripherals, DCDC converters, CPUs, accelerators, volatile/non-volatile memories, and radios all well represented at ISSCC.
However state-of-the-art circuits do not automatically translate to a state-of-the-art system. This tutorial presents an overview of system components and their system efficiency considerations, using published systems as examples. Future trends, such as battery-free energy harvesting, will also be covered.
Bio- James Myers leads the Devices, Circuits and Systems team within Arm Research, which seeks to push compute to the furthest extremes of cost, efficiency, performance, and integration. He joined Arm in 2007 initially responsible for reference implementation flows for the whole processor family. Joining R&D full time from 2009, he has since focused on deployable techniques for reduction of CPU and SoC power, embodied across more than a dozen tapeouts. James holds 20 granted and 16 pending US patents, co-authored one book chapter, and has presented at ISSCC and VLSI Circuits Symposium. His current interests include energy harvesting, printed electronics, sub-threshold circuits, and better-than-worst-case design.
