With one of the most significant computer architecture papers of 2015, ECE faculty Yuan Xie and graduate student Shuangchen Li are recognized by the Institute of Electrical and Electronics Engineers (IEEE) Micro’s Top Picks
Their paper titled “Architecture Exploration for Ambient Energy Harvesting Nonvolatile Processors,” which was originally published in 21nd IEEE Symposium on High Performance Computer Architecture (HPCA 2015) and won the best paper award, was chosen by IEEE’s Micro magazine for its 2016 issue on “Micro’s Top Picks from the Computer Architecture Conferences”, and published as “Nonvolatile Processor Architectures: Efficient, Reliable Progress with Unstable Power ” in IEEE MICRO Vol.36, Issue 3.
The paper explores the design space for a nonvolatile processor across different architectures, input power sources, and policies for maximizing forward progress in a framework calibrated using measured results from a fabricated nonvolatile processor. The UCSB team, together with collaborators from Penn State and Tsinghua University, proposes a heterogeneous microarchitecture solution that efficiently capitalizes on ephemeral power surpluses.
IEEE Micro magazine publishes its yearly “Micro’s Top Picks from the Computer Architecture Conferences”, which collects the previous year’s most significant research papers in computer architecture based on novelty and potential for long-term impact. Any computer architecture paper (not a combination of papers) published in the top conferences of prior year is eligible. The Top Picks committee recognizes those significant and insightful papers that have the potential to influence the work of computer architects for years to come. Li and Xie’s paper is one of the 11 final winners out of hundreds of candidates selected by the committee.
