Complex applications requiring heterogenous processing resources are often described by task graphs\nwith data dependencies. Here\, the nodes represent actors or tasks which are typically activated periodically based on the\navailability of data. One prominent domain of applications fitting this model is stream processing. Here\, it is often important to guarantee\neither bandwidth or execution time requirements. But more recently\, also security\, energy and reliability aspects impose\nconstraints on the mapping of the tasks as well as their communication to cores\, respectively routes in the underlying NoC. \nConcerning mapping methodologies\, we first present a class of algorithms that perform “Self-Embedding”. The idea is here that\na source node issues a request to find appropriate resources to embed its sucessor tasks\, and so on.\nThe next class of techniques introduced is called “Hybrid Application Mapping (HAM)”. Here\, a careful analysis and\ncharacterization of symmetric mappings by constellations of cores and routes is explored in a static (compile-time)\nphase called “Design Space Exploration (DSE)”. At run-time\, the operating system then only needs to search within such\npre-analysed constellations for finding a concrete mapping that will satisfy the given non-functional constraints by construction.\nWe present ideas of how timing constraints may be statically analysed in case of compositional MPSoC architectures such that\ndeadlines or throughput requirements will be automatically met for streaming applications.\nFinally\, we conclude with a discussion on resource constellations that may satisfy certain security requirements on an MPSoC. \nBiography: \nJürgen Teich is with Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU)\, Germany\, where he is directing\nthe Chair for Hardware/Software Co-Design since 2003.

However\, grocery shopping can be a frustrating experience for those with visual impairment. While getting to a grocery shop itself is not as much of a challenge for them\, locating and picking the items in the grocery shelf becomes a task as challenging as picking a needle from the haystack. Imagine picking up five items for your dinner recipe from a typical grocery store in the US that carries around 35\,000 unique items and can have more than 30 aisles spanning 45\,000 square meters. This talk will showcase synergistic advances in algorithms\, architectures and interface design for assisting those with visual impairment to do shopping. We will specifically focus on new non-boolean hardware approaches to significantly impact the energy-efficiency of the overall system. \nBiography: \nVijay Narayanan is a Distinguished Professor of Computer Science and Engineering and Electrical Engineering at The Pennsylvania State University.

Examples of such systems include avionic systems\, industrial control and civil infrastructure monitoring. In a CPS\, sensors and actuators are used to monitor and control the physical components while the computational fabrics determine the control values for the actuators based on the sensed data. All CPSs require timely delivery of sensed data from sensors to the computing fabrics and control signals from the computing fabrics to actuators. Managing the limited resources (e.g.\, computation power and communication bandwidth) to meet the timing requirements in a CPS is a challenging task. Even more challenging is that CPSs should degrade gracefully in the presence of various external disturbances such as failure in critical civil infrastructures and malicious attacks. \nIn this talk\, I first give a general introduction of WNCSs and the challenges that they present to network resource management. In particular\, I will discuss the complications due to external disturbances and the need for dynamic data-link layer scheduling. I then highlight our recent work that aims at tackling this challenge. Our work balances the scheduling effort between a gateway (or access points) and the rest of the nodes in a network. It paves the way towards decentralized network resource management in\norder to achieve scalability. Experimental implementation on a wireless test bed further validates the applicability of our proposed research. I will end the talk outlining our on-going effort in this exciting and growing area of research. \nXiaobo Sharon Hu is a professor in the department of Computer Science and Engineering at the University of Notre Dame\, Notre Dame\, Indiana\, USA.

Instead\, mobile flash storage often equipped with scarce built-in RAM\, slow embedded processors and low-cost flash memories\, all of which make it a challenge to apply traditional techniques for I/O performance improvements. This talk presents a couple of work that we have done recently to optimize I/O for Mobile Flash Storage. First\, this talk will introduce a novel I/O scheduling approach to improve demand-based page-level mapping cache performance. This technique generates mapping cache friendly I/O workloads by strengthening I/O locality at host I/O scheduler. Both temporal locality and spatial localities are taken into consideration for I/O scheduling. Second\, this talk will present a lightweight data compression technique at the flash controller to reduce write pressure on mobile flash storage. It first characterizes data compressibility based on real smartphones\, and the analysis shows that write traffics bound to mobile storage volumes are highly compressible. This technique is the first to investigate firmware-based data compression for mobile flash storage without adding extra data compression hardware. Experimental results demonstrate the proposed techniques outperform state-of-the-art schemes in terms of I/O latency and flash memory lifespan. \nBiography: \nDr. Chun Jason Xue is an Associate Professor at City University of Hong Kong Computer Science Department.

In-situ runtime monitoring and verification can enable a system to introspectively ensure the system is operating correctly in the presence of dynamic environment\, to rapidly detect failures\, and to provide detailed execution traces to find the root cause thereof. Two key challenges faced in using in-situ runtime verification for embedded systems include 1) efficiently defining and automatically constructing a requirements model for embedded system software and 2) minimizing the runtime overhead of observing and verifying the runtime execution adheres to the requirements model. In this talk\, we present a methodology to construct a hierarchical runtime monitoring graph from system requirements specified us- ing multiple UML sequence diagrams\, which are already commonly used in software development. We further present the design of on-chip hardware that nonintrusively monitors the system at runtime to ensure the execution matches the requirements model. We evaluate the proposed methodology using a case study of a fail-safe autonomous vehicle subsystem and analyze the relationship between event coverage\, detection rate\, and hardware requirements. \nBiography: \nMinjun Seo is a Ph.D. Candidate in the Department of Electrical and Computer Engineering at the University of Arizona.  His current research focuses on efficient specification and implementation of in-situ requirements monitoring of embedded systems.

Many signs of deterioration exist as early as 24 hours prior having a serious impact on the health of a person. As hospitalization times have to be minimized\, in-home or remote early warning systems can fill the gap by allowing in-home care while having the potentially problematic conditions and their signs under surveillance and control. \nEarly warning score (EWS) is an approach to detect the deterioration of a patient. It is based on a fact that there are several changes in the physiological parameters prior a clinical deterioration of a patient. Currently\, EWS procedure is mostly used for in-hospital clinical cases and is performed in a manual paper-based fashion. However\, it is possible to build an automated EWS health monitoring system to intelligently monitor vital signs and prevent health deterioration for in-home and hospitalized patients using Internet-of-Things technologies. \nBiography: \nPasi Liljeberg received the MSc and PhD degrees in electronics and information technology from the University of Turku\, Turku\, Finland\, in 1999 and 2005\, respectively.

Near-threshold computing (NTC) in CMOS is a promising alternative for any application which can tolerate or benefit from very wide voltage-frequency scaling (VFS). The digital blocks of devices may operate at very different power-performance modes\, from sub-MHz to peaks of hundreds of MHz\, which requires CMOS design libraries targeted for NTC. The analog and RF content on IoT chips will be even more crucial\, from a power-savings standpoint. In IoT it is best to avoid using costlier CMOS\, and yet closer to an end\, two-dimensional transistor and IC scaling. The nano-power range which is achievable in deca-nanometer CMOS at near-VT requires very specific logic design techniques to be applied in digital CMOS. This talk addresses a method to design CMOS digital circuits for a wide dynamic range of VFS\, and targets near-threshold for best energy-efficiency. Our work on 65nm CMOS has demonstrated 63X to 77X energy/operation savings for applications that tolerate ultra-wide frequency scaling (from hundreds of KHz to 1GHz) in their system operating modes. The results in CMOS were obtained using the minimal cycle time achievable at each supply voltage\, down to very low 200 mV supplies. The strategy for transistor sizing in digital cells and static noise margin maximization will be addressed in particular. The seminar seeks to stimulate system-level and circuit-level design approaches for IoT nodes\, as the presenter is available to discuss digital\, mixed-signal\, and even RF aspects of CMOS systems-on- IoT-devices. \nBiography: \nSergio Bampi received the B.Sc in Electronics Engineering and the B.Sc. in Physics from the Federal Univ. of Rio Grande do Sul (UFRGS\, 1979)\, and the M.Sc. and Ph.D. degrees in EE from Stanford University (USA) in 1986.

It has been a very challenging but deeply fulfilling journey. Globally there are many technology solutions available for addressing the mobility as well as education needs of the visually impaired. Unfortunately they fail to address the challenges of mobility and education in India and other developing countries and even if they do they are completely unaffordable. In this talk I would tell the story of development and dissemination of devices and technologies like SmartCane\, OnBoard and Tactile Diagrams. These started in the ASSISTECH laboratory as inter-disciplinary projects and are today slowly finding their way to the users. \nBiography: \nM Balakrishnan has a B.Tech.(EEE) from BITS Pilani and PhD(EE) from IIT Delhi. He has been\ninvolved in teaching and research in EDA\, VLSI and Embedded systems for more than three decades. He has published over 120 papers in leading journals and conferences\, supervised 13 PhD students and over 180 B.Tech. and M.Tech. student projects. He has held visiting positions in Canada\, US and Germany. He has founded the ASSISTECH laboratory at IIT Delhi which is engaged in finding affordable technology based solutions for education and mobility of visually impaired. He is a recipient of two national awards for his work in the disability space. He has been HoD(CSE)\, Dean(Post Graduate Studies & Research)\, Deputy Director(Faculty) and is currently Deputy Director(Strategy & Planning) at IIT Delhi.

As such\, the security of this communication standard is of paramount importance. However\, there is concerning inherent protocol security threats in LTE due to the large amount of unauthenticated and unprotected messages exchanged between a base station and a mobile device prior to the authentication security handshake. \nOpen source implementations of the LTE standards rapidly matured within the last couple of years. This\, in combination with sophisticated yet low cost software radio hardware\, fueled a new wave of security research that identified numerous protocol security issues in LTE that could allow an adversary to deny the service of mobile endpoints and track the location of users. This talk will summarize an ongoing effort on protocol-fuzzing LTE mobile networks using open-software tools. The protocol exploits against mobile endpoints that were discovered two years ago will be discussed as an introduction to the new systematic approach to protocol-fuzz LTE networks\, introducing as well a series of new potential exploits in the uplink\, against the network infrastructure and mobile devices outside of the radio range of the adversary. \nFinally\, these LTE protocol exploits are analyzed in the context of the recently (December 2017) published first release of the 3GPP 5G specifications (3GPP Rel. 15) for the 5G Radio Access Network (5G New Radio) and Core Network (5G System). Unfortunately\, not only most protocol-aware radio jamming issues and LTE protocol exploits are still a potential threat\, but there is a large number of new pre-authentication messages and new fields to already existing messages that could open the doors to further 5G-specific exploits. \nBiography: \nRoger Piqueras Jover is a Wireless Security Research Scientist and Security Architect at the CTO Security Architecture team of Bloomberg LP\, where he leads projects on mobile/wireless security and is actively involved in hardware security\, network security\, machine learning and anomaly/fraud detection.
