The Latest News on Networks-on-Chip: from Advanced Use Cases to Emerging Technologies
Davide Bertozzi, University of Ferrara, Italy


The concept of "communication-based design" dates back to the early 2000s, when the early networks-on-chip (NoCs) were gaining momentum. Twenty years later, that concept still holds, but at a radically different abstraction level: it refers to novel system-level design paradigms leveraging the enabling features of communication architectures *and* emerging technologies. In this context, network-on-chip research is again on the rise, and even more exciting, since researchers have to break barriers between disciplines and take a fundamental cross-layer approach to design and optimization.

This course pursues the goal of introducing attendees to some of the most advanced application frontiers of NoCs across several domains. With respect to conventional NoC courses, this one will take the distinctive perspective of designing the NoC as a key enabler for novel system-level design paradigms. The novel content of the course is structured into four parts.

The first part addresses NoCs for data-intensive, context-aware devices and services that use rich Internet-of-Things (IoT) data to perceive, model and adapt to their environment and users.

The second part addresses the current relentless effort to design computing systems that work more and more like the brain, and where large-scale connectivity is recognized to be one key element of brain's capabilities.

The third part addresses communication in systems leveraging 2.5D interposer-based integration, which exhibit a heterogeneous network-on-chip/network-on-interposer (NoI) interconnection fabric.

Finally, the fourth part envisions the extension of the on-chip networking paradigm to ultra-large-scale systems and/or to high-performance computing ones by replacing the technological substrate. The focus will be on silicon nanophotonic networks and on their interface with electronics.

Overall, the course covers hot upcoming research and development trends, and is a stepping stone into the next decade of network-on-chip research.


Davide Bertozzi is currently an Associate Professor at University of Ferrara (Italy), where he leads the MPSoC Research Group. He got his Bachelor Degree in Electrical Engineering from University of Bologna in 1999, and his PhD in Electrical and Computer Engineering from the same University in 2003. The mission of his research is to stay at the forefront of system innovation by leveraging the enabling properties of communication architectures and emerging technologies. He has published around 180 scientific contributions in the field of interconnect-centric design, and co-edited one book on networks-on-chip in 2010. He has worked in several research projects funded by the European Union (Galaxy, NaNoC, vIrtical) and coordinated a pioneering national project on the applications of silicon photonics to computer communications (Photonica). He has been visiting researcher at international academic institutions (Stanford University) and semiconductor companies (STMicroelectronics, NXP, Samsung, NEC). In 2018 he received the Wolfgang Mehr Award from the IHP Leibniz Institute for Innovative Microelectronics (Germany) for his research in the field of electro-optical interconnection fabrics and of their interfaces.
