Our paper titled "Energy Aware Memory Mapping for Hybrid FRAM-SRAM MCUs for IoT Edge devices" won the Best Paper Award at the 29th International Conference on VLSI Design and 15th International Conference on Embedded Systems. Related news could be found here.

The paper talks about two techniques em-Map and Energy-Align that make intermittently powered IoT system energy-efficient. Intermittently powered IoT systems suffer from sudden and abrupt power failures, which makes it challenging to perform reliable computations on them. Em-Map is a dynamic memory mapping technique that maps functions constituting a program across SRAM and FRAM (Ferroelectric RAM), thereby optimizing energy-consumption and improving performance without sacrificing reliability. Energy-Align is a technique that reduces the overhead required to perform the necessary book-keeping that enable the IoT systems to compute across the power failures. More information could be found in the paper.

Design Contest Winner, Qube

Our design, QUBE, won the Design Contest Award at the 28th International Conference on VLSI Design and 14th International Conference on Embedded Systems. Related news can be found here.

The QUBE is a modular embedded hardware platform that enables computing across power cycles in transiently powered IoT systems by saving the program state in-situ using an emerging non-volatile memory (FRAM). The modular stack-based architecture facilitates easy customizability and expansion while accelerating the design, debug, and prototyping phases.

Design Contest Winner, Senergy

Our design, Senergy, won the Design Contest Award at the IEEE/ACM International Symposium on Low Power Electronics and Design 2014. 

Senergy is an embedded system that uses the concept of harvesting and gathering energy from passive sensors when the system is idle, and using it to power sub-systems. In our demonstration, we were able to harvest energy from a light sensor (whenever light was not being sensed by the MCU) and use it to power a real-time clock (RTC) continuously.
