Keynote Talks

Keynote 1

Date: October 4th, 2018
Speaker: Vivek De (Intel)
Title: Many-Core SoC in Nanoscale CMOS: Challenges & Opportunities


Many-core SoC designs in scaled CMOS process demand wide dynamic voltage-frequency operating range, spanning multi-threaded high-throughput near-threshold voltage (NTV) to single-threaded burst performance modes, as well as fine-grain multi-voltage design and spatio-temporal power management to deliver maximum performance under stringent thermal and energy constraints. Interconnect scaling bottlenecks, process-voltage-temperature variations and aging-induced degradation pose major challenges going forward. We present key circuit and design techniques for logic, memory and on-die interconnect networks that enable efficient, variation-tolerant and resilient many-core SoC designs in nanoscale CMOS.

Speaker: Giovanni De Micheli (EPF Lausanne, Switzerland)
Title: NoCs: a short history of success and a long future


The broad application of NoCs in IC design has been enabled by NoC synthesis tools that evolved from university prototypes to full commercial synthesis flows. NoC embodiments are ubiquitously present in circuits and systems. As systems evolve to include new components and features, NoCs will play even a more important role as the smart connect that can enable heterogeneity.Thus this field will both evolve in diversity of implementations as well in the search of both higher performance and lower power solutions.

Special Sessions and Tutorial

Special Sessions

  1. “Securing Networks-on-Chip: A Cross-Technology Perspective”
    Organizer: Sudeep Pasricha, Colorado State University
    Other Speakers: Tushar Krishna, Georgia Institute of Technology; Travis Boraten, Ohio University
    Abstract: This special session will discuss the security challenges in NoC design across the electrical, photonic, and wireless implementation domains, and propose several promising solutions to overcome them. The NOCS community will find the topic of this special session to be extremely relevant and interesting as traditionally the community has not focused on security as much as other design metrics such as performance or energy. Not only will the special session educate and inform attendees about security issues in NoCs across a broad set of implementation technologies, but many of the solutions that will be presented are likely to spark new ideas for NOCS attendees to integrate security into their sub-domain of expertise. This special session will foster a valuable cross-domain exchange of ideas between experts in security, emerging technologies, and NoC design, that is very likely to benefit the industry practitioners and researchers in the NOCS community.

  2. “Realistic Wireless Channel Modelling for Parallel Applications on NoC-based MPSoC”
    Organizers/Speakers: Jean-Philippe Diguet, Lab-STICC, France; Sujay Deb, IIIT Delhi, India; Sergi Abadal, Universitat Politècnica de Catalunya, Spain
    Abstract: Wireless Network-on-Chip (WNoC) is considered as a promising solution in the context of manycore architectures. Unfortunately, WNoC still suffer from important limitations. The first one is the power consumption of the analog part of the transceivers with is one order of magnitude (tens mW) larger than the power consumption of digital components. Secondly, at network level no feasible simulation is possible today with the existing setup. Apart from transceiver component in WNoC, channel modelling is one of the major concerns. Finally, multiple important radio parameters with strong impacts on communication quality and efficiency are not considered or based on simple and non-meaningful models. The special session addresses this specific but key challenge for future NoC. Research in that area require multidisciplinary teams including NoC experts (architecture, protocols, simulators) and High Frequency radio experts (channel modeling, transceiver design along with digital components, antennas). It will be based on talks and papers from three research groups that investigate this important problem with a multidisciplinary approach.

  3. “Networks Meet Network: Shaping the On-chip Network for Complex Networks”
    Organizers: Xiaohang Wang, South China University of Technology; Amit Kumar Singh, University of Essex, UK.
    Speakers: Masoud Daneshtalab, Amit Kumar Singh
    Abstract: Various emerging applications are in the form of complex networks, e.g., neural networks, deep learning, social networks, protein networks, brain neural connections, and many other applications. A key feature of these applications are "linked", i.e., time varying topologies, complex connection structure, and highly dynamic runtime behaviors. Conventional many-core architecture are inefficient for these "linked" complex network applications, as most of them are using fixed, low-degree mesh network for sustaining on-chip communication, which cannot be adapted to the highly dynamical features of these applications. Therefore, this special session, covers the topic of the interplay of new on-chip networks which can adapt their communication infrastructure to these complex network applications.


  • "Approximate Computing for Networks on Chip"
    Organizers: Dr. Jie Han (University of Alberta) and Dr. Eun Jung (EJ) Kim (Texas A&M University).
    1. Part I: "Approximate Arithmetic Circuits"
      Speaker: Dr. Jie Han
      Abstract: The demand of higher speed and power efficiency, as well as the feature of error resilience in many applications (e.g., multimedia, recognition and data analytics), have driven the development of approximate computing circuits. Often as the most important arithmetic modules in a processor, adders, multipliers and dividers determine the performance and energy efficiency of many computing tasks. In this talk, a review and classification are presented for the current designs of approximate arithmetic circuits including adders, multipliers and dividers. A comprehensive and comparative evaluation of their error and circuit characteristics is performed for understanding the features of various designs. Image processing and cerebellar models are considered to show the effectiveness of the approximate arithmetic circuits in improving the energy efficiency and performance of computation-intensive applications.

    2. Part II: "Approximate Networks on Chip"
      Speaker: Dr. Eun Jung (EJ) Kim
      Abstract: The trend of unsustainable power consumption and large memory bandwidth demands in massively parallel multicore systems, with the advent of the big data era, has brought upon the onset of alternate computation paradigms utilizing heterogeneity, specialization, processor-in-memory and approximation. Approximate Computing is being touted as a viable solution for high performance computation by relaxing the accuracy constraints of applications. This trend has been accentuated by emerging data intensive applications in domains like image/video processing, machine learning and big data analytics that allow inaccurate outputs within an acceptable variance. Leveraging relaxed accuracy for high throughput in Networks-onChip (NoCs), which have rapidly become the accepted method for connecting a large number of on-chip components, has not yet been explored. In this talk, I will present APPROX-NoC, a hardware data approximation framework with an online data error control mechanism for high performance NoCs. APPROX-NoC facilitates approximate matching of data patterns, within a controllable value range, to compress them thereby reducing the volume of data movement across the chip.
