Salama\, King Abdullah\, University of Science and Technology\, Saudi Arabia \nDate and Time: Thursday\, February 18\, 2016 at 11:00 A.M. \nLocation: Engineering Hall 2430 \nHosts: Fadi J. Kurdahi and Ahmed Eltawil \nAbstract: Energy efficiency is a key requirement for wireless sensor nodes\, biomedical implants\, and wearable devices. The energy consumption of the sensor node needs to be minimized to avoid battery replacement\, or even better\, to enable the device to survive on energy harvested from the ambient. Capacitive sensors do not consume static power; thus\, they are attractive from an energy efficiency perspective. In addition\, they can be employed in a wide range of sensing applications\, such as pressure\, humidity\, biological\, and chemical sensing. However\, the capacitive sensor readout circuit—i.e.\, the capacitance-to-digital converter (CDC) —can be the dominant source of energy consumption in the system. Thus\, the development of energy-efficient CDC architectures is crucial to minimizing the energy consumption of capacitive sensor nodes. In the first part of this talk\, we propose several energy -efficient CDC architectures for low-energy sensor nodes. In the second part\, we study the matching properties of small integrated capacitors\, which are an integral component of energy-efficient CDCs. Despite conventional wisdom\, we experimentally illustrate that the mismatch of small capacitors can be directly measured\, and we report experimental mismatch measurements for sub-femtofarad integrated capacitors. We also correct the common misconception that lateral capacitors match better than vertical capacitors\, and we identify the conditions that make one implementation preferable. \nBio: Dr. Salama received his bachelor’s degree with honors from the Electronics and Communications Department at Cairo University in Egypt in 1997\, and his master’s and doctorate degrees from the Electrical Engineering Department at Stanford University in the United States\, in 2000 and 2005 respectively.

In this talk we discuss fundamental concepts towards a first attempt in applying EDA design methodologies that are widely used for electronics systems design to the case of the design of EESs. CAD for EESs encompasses modeling\, simulation\, design and optimization and is a challenging task that mandates a multidisciplinary and heterogeneous approach. We identify similarities and differences between electrical energy systems and electronics systems in order to inherit as much as possible the profound legacy resources of EDA. The talk analyzes in deeper details the issue of representation\, modeling\, and simulation of EESs\, tasks that naturally precede synthesis and optimization in a typical design flow.\n\n\n\n\n\nBio: Massimo Poncino is Full Professor of Computing Systems at Politecnico di Torino.

PC-based simulations are slow and inaccurate. Using physical mockups\, like connecting a ventilator device to a balloon acting as a lung\, can’t support sufficiently diverse scenarios\, like fluid in the lungs. This talk describes joint UCR/UCI work on developing “digital mockups” — models of physiological systems that execute in real-time\, supporting thorough testing of device software. We show that FPGAs (field-programmable gate arrays) — widely-available programmable chips having a unique execution approach that we’ll describe — are an excellent match for executing physiological models\, yielding order-of-magnitude speedups over PCs\, GPUs\, and other computing approaches. The talk describes the synthesis approach to automatically converting models\, consisting of thousands of differential equations\, into networks of processing elements on FPGAs. Real-time execution of physiological models can also be useful in building complete human simulators\, used today medical and nursing schools. More broadly\, real-time execution of physical systems (chemical\, biological\, mechanical\, physiological\, etc.) can be useful in the design of a wide variety of what today are called cyber-physical systems– systems where computers interact closely with the physical world – including automobiles\, aircraft\, medical equipment\, military equipment\, manufacturing systems\, and much more. \nBio: Frank Vahid is a Professor of Computer Science and Engineering at the University of California\, Riverside (B.S. 1988 Univ. of Illinois in 1988\, M.S./Ph.D. 1990/1994 Univ.of California\, Irvine.

Variability in supply voltage\, chip temperature\, manufacturing process\, and transistor aging have imposed a large amount of pessimistic margins in clock frequency\, voltage\, and device size\, which has severely undermined gains from various boundary-pushing efforts. We will present (1) a low-overhead\, in-sit\, within-a-cycle timing-error detection and correction technique that can operate at near/sub-threshold voltage\, (2) ultra-compact thermal sensor circuits enabling 10-100X denser on-chip thermal sensing\, (3) self-testing circuits and frameworks for in-field & in-sit aging monitoring in pipeline and SRAM register files. Several test chip measurement results will be presented. \nBio: Mingoo Seok is an assistant professor in the Department of Electrical Engineering at Columbia University.

These benefits have contributed to the wide-scale acceptance of the cloud computing paradigm and growing adoption by the industry. With this growth\, limitations of this paradigm are beginning to surface. One such limitation is that contemporary clouds are not interoperable. This limitation arises due to proprietary technologies\, heterogeneous interfaces and the tight tethering of service offerings to the host cloud. Current research solutions for enabling cloud interoperability are predominantly provider-centric\, requiring cloud providers to adopt and implement the changes that facilitate interoperation. This approach faces several hurdles and can take a long time to hit the market. In the meantime\, a client-centric approach to interoperation is necessary for providing its benefits to consumers in the current cloud ecosystem. To this end\, a novel framework for cloud interoperation called collaborative cloud computing is proposed. The proposed framework provides dynamic\, on-the-fly collaborations and resource sharing among cloud-based services\, without pre-established collaboration agreements or standardized interfaces\, through use of client-controlled mediating agents called proxies. \nBio: Mukesh Singhal is a Chancellor’s Professor in the Computer Science and Engineering program at the University of California\, Merced.

The process of designing hardware requires trusting intellectual property (IP) cores and computer-aided design (CAD) tools developed by third parties\, as well as the fabrication\, packaging\, assembly\, and delivery of the final system. Valuable IP is vulnerable to theft and modification during tape-out\, even if a perfect design free of security flaws is sent to the foundry. Of course\, no design is ever perfect\, and having a trusted foundry does not solve the problem of flawed designs. Furthermore\, the trusted foundry may not have the capability to deliver the most aggressive technology node\, volume\, yield\, or cost. Even the extraordinary step of building everything from scratch in-house\, including all of the tool chains\, both digital and analog\, is not guaranteed to result in a trustworthy design. \nBio: Ted Huffmire is an Assistant Professor of Computer Science at the Naval Postgraduate School in Monterey\, California. His research spans both computer security and computer architecture\, focusing on hardware-oriented security and the development of policy enforcement mechanisms for application-specific devices.

Kurdahi \nAbstract: FPGAs have grown from a simple logic replacement to fully-programmable SoC\, with multi-core CPU subsystems\, a broad spectrum of peripherals\, hundreds of thousands of gates of programmable logic and high-speed multi-gigabit transceivers. As the complexity of the underlying hardware has grown\, so has the value of the applications built in them and the data handled by them. Traditional FPGA bitstream security has been enhanced to address these greater security requirements. This talk presents an overview of hardware security issues and the security features of the Zynq All- Programmable SoC. The secure boot process includes asymmetric and symmetric authentication as well as symmetric encryption to protect software and programmable hardware during programming.During operation the hardware can disable test ports\, monitor on-chip power and temperature and detect tampering with configuration data. ARM Trust Zone is integrated through the AXI busses into both the processor and the programmable logic subsystems. \nBio: Dr. Stephen Trimberger holds a M.S. degree in ICS from UCI and a Ph.D. degree from California Institute of Technology.

Traditional triggers base on rare events\, such as rare values or sequences. While in most cases these trigger circuits are able to hide a Trojan attack\, exhaustive functional simulation and testing will reveal the Trojan due to violation of the specification. Our trigger behaves functionally and formally equivalent to the hardware description language (HDL) specification throughout the entire FPGA design flow\, until the design is written by the place-and-route tool as bitstream configuration file. From then\, Trojan payload is always on. We implement the trigger signal using a 4-input lookup table (LUT)\, each of the inputs connecting to the same signal. This lets us directly address the least significant bit (LSB) and most significant bit (MSB) of the LUT. With the remaining 14 bits\, we realize a “magic” unary operation. This way\, we are able to implement 16 different Triggers. We demonstrate the attack with a simple example and discuss the effectiveness of the recent detection techniques unused circuit identification (UCI)\, functional analysis for nearly-unused circuit identification (FANCI) and VeriTrust in order to reveal our trigger. \nBiography: Christian Krieg received the bachelor’s and master’s degree in electrical engineering from TU Wien and is now pursuing his PhD studies on hardware security at TU Wien.

Constantinides\, Imperial College London\, UK \nDate and Time: Wednesday\, November 16\, 2016 at 11:00 A.M. \nLocation: Engineering Hall 2430 \nHost: Professor Nikil Dutt \nAbstract: High Level Synthesis – synthesis of circuits from behavioral descriptions – is a long-standing problem\, but one that appears to now have come to age. Both the demand for\, and the supply of\, quality HLS tools is now in place. However\, there are still some hard problems to be overcome in order to make HLS fully general. My research focuses on two of these: customization of memory systems to algorithms\, and customization of number representation to algorithms. After briefly introducing the work at Imperial – and encouraging PhD and postdoc applications (!) – I will spend a little time on each of these problems. In particular\, I will look at the problem of customization of memory for heap manipulating programs\, the potential of parametric analysis for synthesis of lightweight run-time scheduling changes\, and automates code refactoring for rigorously controlled accuracy / latency / area optimization. I hope to inspire the audience to consider how you may be able to contribute to these problems. \nBiography: Prof George A. Constantinides holds the Royal Academy of Engineering / Imagination Technologies Chair in Digital Computation at Imperial College London\, where he leads the Circuits and Systems research group.

One of the metrics\, so far largely unexplored\, which has to be used to identify a good lightweight design is the energy consumed per unit operation of the algorithm. For block ciphers\, this operation is the encryption of one plaintext. \nThis talk will address several approaches for reducing the energy consumption of existing block ciphers\, touching the design space of the AES algorithm\, to which few algorithmic optimizations are applied. \nThe gained experience lead to the design of Midori\, the first block cipher designed to optimize the energy consumed per bit in encryption or decryption operation. Each component of the circuit\, as well as its entire architecture of the cipher\, have been optimized for energy\, and design choices leading to low energy consumption in an electrical circuit were taken. Achieved results demonstrate that the energy consumption of Midori64 and Midori128 is much lower that current stateof the art.\n \nBiography: Dr. Francesco Regazzoni is a senior researcher at the the ALaRI Institute of Universita’ della Svizzera italiana (Lugano\, Switzerland).

In addition to traditional web service sector\, this also includes sectors such as telecommunication (e.g.\,  software defined network  applications)\, and healthcare (e.g.\, GE Cloud Health and Cloud PACS ). Cloud servers to process big data are now aggregating multiple disparate workloads with heterogeneously structured and unstructured data (image\, text\, video\, graph) with varying performance goals (batch\, streaming\, real-time\, and near-real-time). Emerging analytics applications in these domains rely heavily on specific deep machine learning and mining algorithms\, and are running complex database software stack with significant interaction with I/O and OS and sharing many inherent characteristics that are fundamentally different from traditional CPU and parallel applications. Emerging big data applications require computing resources that can efficiently scale to manage massive amounts of diverse data. However\, the rapid growth in the data yields challenges to process them efficiently using current cloud server architectures such as high performance Xeon. Furthermore\, physical design constraints\, such as power and density\, have become the dominant limiting factor for scaling out servers. To respond to these challenges\, heterogeneous architectures which integrates big and little cores with FPGA accelerators has emerged as a promising solution. In this talk\, through methodical investigation of power and performance measurements\, and comprehensive system level and micro-architectural analysis\, I first show the characterization results of emerging big data applications on big Xeon and little Atom-based servers. The characterization results across a wide range of real-world big data applications and various software stacks demonstrate how the choice of big vs little core-based server for energy-efficiency is significantly influenced by the size of data\, performance constraints\, and presence of accelerator. Furthermore\, the microarchitecture-level analysis highlights where improvement is needed in big and little core servers. \nSecond\, I will show how in a heterogeneous architecture effective mapping of Hadoop and Spark MapReduce based applications to FPGA accelerator can significantly increase the energy-efficiency and performance. The real-system results show promising kernel speedup of more than 100X and significant energy-efficiency gains. \nBiography: \nHouman Homayoun is an Assistant Professor of the Department of Electrical and Computer Engineering at George Mason University.

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. This walk presents a remote monitoring and diagnostic system that provides a holistic perspective of patients and their health conditions. It discusses how the concept of self-awareness can be used in various parts of the system such as information collection through wearable sensors\, confidence assessment of the sensory data\, the knowledge base of the patient’s health situation\, and automation of reasoning about the health situation. This approach to self-awareness provides \n(i) situation awareness to consider the impact of variations such as sleeping\, walking\, running\, and resting\, \n(ii) system personalization by reflecting parameters such as age\, body mass index\, and gender\, and \n(iii) the attention property of self-awareness to improve the energy efficiency and dependability of the system via adjusting the priorities of the sensory data collection.\nBiography: \n Axel Jantsch received the Dipl.Ing. and Dr. Tech. degrees from TU Wien\, Vienna\, Austria\, in 1988 and 1992\, respectively.

Private local memories play a key role in the design of these components both with respect to performance optimization and because they are responsible for most of their area and power dissipation. Each local memory unit is usually implemented with a multibank microarchitecture based on the combined requirements of each hardware block accessing the corresponding data. However\, the creation of these multibank memory microarchitectures is not well supported by current design flows\, and the designers must perform this tedious and error-prone process manually. \nIn this talk\, I will present a system-level methodology for the generation of multi-bank memories in heterogeneous architectures. The methodology is supported by Mnemosyne\, an open-source prototype CAD tool that can be easily integrated into commercial design flows. Mnemosyneincludes various technology-aware optimizations to reduce the memory cost (area and power) by efficiently reusing the physical banks for storing different data. With Mnemosyne\,we can reduce the memory cost of single accelerators by up to 45%. Moreover\, when reusing memory IPs across accelerators\, we achieve area savings that range between 17% and 55% compared to the case where the memory elements are designed separately. \nBiography: \nChristian Pilato is a Postdoctoral Researcher at the ALaRi institute of Università della Svizzera italiana (USI)\, Lugano\, Switzerland.

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.
