3D Interconnect Architectures for Heterogeneous Technologies

This book describes the first comprehensive approach to the optimization of interconnect architectures in 3D systems on chips (SoCs), specially addressing the challenges and opportunities arising from heterogeneous integration. Readers learn about the physical implications of using heterogeneous 3D technologies for SoC integration, while also learning to maximize the 3D-technology gains, through a physical-effect-aware architecture design. The book provides a deep theoretical background covering all abstraction-levels needed to research and architect tomorrow’s 3D-integrated circuits, an extensive set of optimization methods (for power, performance, area, and yield), as well as an open-source optimization and simulation framework for fast exploration of novel designs.

Lennart Bamberg received the B.Sc., M.Sc., and Ph.D. (Dr.-Ing. ) degree with highest honours (“summa cum laude”) in electrical and computer engineering from the University of Bremen, Germany, in 2014, 2016, and 2020, respectively. In 2019, he was a Visiting Research Scholar at the Georgia Institute of Technology, Atlanta (USA). This stay was funded by a scholarship of the German Academic Exchange Service, DAAD, and the German Federal Ministry of Education and Research, BMBF. Afterwards, he was a Technical director at GrAI Matter Labs, where he was in charge of the processor architecture for edge AI. Since 2022, he is System Architect at NXP Semiconductors working on secure-element SoCs for mobile phones and wearables. In parallel, he serves as a guest lecturer at the University of Bremen in electrical engineering since 2020. Lennart Bamberg’s research interests include low-power and domain-specific computer architectures for embedded systems. He received best-paper awards atinternational conferences and serves as a reviewer and program-committee member for several international conferences and journals.

Jan Moritz Joseph got his B.Sc. in medical engineering in 2011 and his M.Sc. in computer science in 2014 from the Universität zu Lübeck, Germany.  From 2008 to 2014 he was a scholarship holder of the German Merit Foundation (Deutsche Studienstiftung e.V.). Dr. Joseph received his Ph.D. from Otto-von-Guericke Universität Magdeburg, Germany, in 2019. The title of his thesis was "Networks-on-Chip for heterogeneous 3D Systems-on-Chip". His Ph.D. was awarded the highest honours “summa cum laude”. In 2020, he received the award for the best PhD thesis from the Faculty of Electrical Engineering and Information Technology at Otto-von-Guericke Universität Magdeburg, Germany. From 2019 to 2020 Dr. Joseph was a visiting researcher at Dr. Krishna’s Synergy Lab at Georgia Institute of Technology, Atlanta, GA. His stay was partially funded by a scholarship from the German Academic Exchange Service. He joined Institute for Communication Technologies and Embedded Systems, RWTH Aachen University, in June 2020 as a postdoctoral research fellow in the Chair for Software for Systems on Silicon. His research interest are architectures for NoCs, AI accelerators and neuromorphic computing as well as simulation and 3D integration.

Alberto García-Ortiz received the Diploma degree in telecommunication systems from the Polytechnic University of Valencia, Spain, in 1998, and the Ph.D. degree (summa cum laude) from the Department of Electrical Engineering and Information Technology, Institute of Microelectronic Systems, Darmstadt University of Technology, Germany, in 2003.,He worked at NewLogic, Austria, for two years. From 2003 to 2005, he worked as a Senior Hardware Design Engineer at the IBM Deutschland Research and Development, Böblingen. Then, he joined the start-up AnaFocus, Spain, where he was responsible for the design andintegration of AnaFocus’ next generation Vision Systems-on-Chip. He is currently a Full Professor for the Chair of Integrated Digital Systems at the University of Bremen. His research interests include low-power design and estimation, communication-centric design, SoC integration, and variations-aware design. Dr. Garcia-Ortiz received the Outstanding Dissertation Award from the European Design and Automation Association, in 2004, and an Innovation Award from IBM, in 2005, for his contributions to leakage estimation; he holds two issued patents for that work. He serves as a reviewer of several conferences, journals, and European projects.
