Research Manuscript: Speculations on Routes to Boost Power and Energy Efficiency
Event TypeResearch Manuscript
Cross-Layer Power Analysis and Low-Power Design
TimeTuesday, December 7th1:30pm - 3:00pm PST
DescriptionThis session describes four methods of designing and managing digital systems to improve their power, energy, and thermal properties. It opens with a lightweight machine learning technique to improve the boostability of multicore systems, considering power, performance, and temperature. The next presentation describes control of runtime dynamic concurrency throttling and frequency boosting parameters to improve OpenMP energy-delay products. The third presentation describes a design space exploration technique using hybrid static/dynamic speculation; it considers most-significant input bits, depth-of-carry histories, and local thread identifiers to improve accuracy. The session closes with an impedance-driven design space exploration tool for board-level power networks.
