This book presents the state-of-the art of one of the main concerns with microprocessors today, a phenomenon known as "dark silicon". Readers will learn how power constraints (both leakage and dynamic power) limit the extent to which large portions of a chip can be powered up at a given time, i.e. how much actual performance and functionality the microprocessor can provide. The authors describe their research toward the future of microprocessor development in the dark silicon era, covering a variety of important aspects of dark silicon-aware architectures including design, management, reliability, and test. Readers will benefit from specific recommendations for mitigating the dark silicon phenomenon, including energy-efficient, dedicated solutions and technologies to maximize the utilization and reliability of microprocessors.
Prof. Dr.h.c Prof.h.c. Hannu Tenhunen is chair professor of Electronic Systems at Royal Institute of Technology (KTH), Stockholm, Sweden. Prof. Tenhunen has held professor position as full professor, invited professor or visiting honorary professor in Finland (TUT, UTU), Sweden (KTH), USA (Cornel U), France (INPG), China (Fudan and Beijing Jiatong Universities), and Hong Kong (Chinese University of Hong Kong), and has an honorary doctorate from Tallinn Technical University.
He has been director of multiple national large scale research programs or being an initiator and director of national or European graduate schools. He has actively contributed on VLSI and SoC design in Finland and Sweden via creating new educational programs and research directions, most lately at European level as being the EU-level Education Director of the new European flagship initiative European Institute of Technology and Innovations (EIT), and its Knowledge and Innovation Community EIT ICT Labs. Prof. Tenhunen has been active in promoting the innovation system and innovation support mechanism in research and education both at national and European level.
Prof. Tenhunen has been a board member in science parks, start-up companies, and has served as advisor or expert for high technology companies and venture capitalists, as well as evaluator for EU and national programs and research institutes. He has supervised over 70 M.Sc. thesis, 39 doctoral thesis, and 8 post-doc. From his doctoral students and post-docs, as of today, 21 are currently professors and associate professors.
