“ThirdEye: Visual Assist for Grocery Shopping”

Title: “ThirdEye: Visual Assist for Grocery Shopping”

Speaker: Prof. Vijaykrishnan Narayanan, Pennsylvania State University, USA

Date and Time: Wednesday, November 15, 2017 at 11:00AM-12:00PM

Location: 2430 Engineering Hall


Shopping is widely considered as a relaxing leisure activity. 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.

“Detecting Hardware Trojans Hidden in Unspecified Design Functionality”

Title: “Detecting Hardware Trojans Hidden in Unspecified Design Functionality”

Speaker: Dr. Nicole Fern, University of California, Santa Barbara

Date and Time: Thursday, November 16th, 2017 at 2:00PM-3:00PM

Location: Donald Bren Hall 3011


Traditional verification methods and metrics attempt to answer the question: does my design correctly perform the intended functionality?  This talk will look at hardware verification from a security perspective, which demands the verification effort answer an additional question: does my design perform malicious functionality in addition to the intended functionality?  The talk will motivate through examples why Hardware Trojans modifying only unspecified design functionality are both powerful and stealthy.  RTL don’t cares and idle cycles in on-chip bus protocols are two examples of unspecified functionality vulnerable to malicious modification that this talk will explore in depth.  This talk will also detail how to formulate the Trojan detection problem as a satisfiability problem in order to leverage existing formal verification tools to highlight Trojans hidden in unspecified functionality.


Nicole Fern received her undergraduate degree in Electrical Engineering from The Cooper Union for the Advancement of Science and Art and her PhD degree in the ECE department at UC Santa Barbara under the advisement of Professor Tim Cheng.  She is now a post-doc at UC Santa Barbara.  Her thesis work focused on developing techniques to verify the absence of Hardware Trojans in unspecified design functionality.  Her current research interests include investigating security issues in emerging memory technologies and at the hardware/software boundary.



“Application Mapping Methodologies for NoC-Based MPSOCs”

Title: “Application Mapping Methodologies for NoC-Based MPSOCs”

Speaker: Jürgen Teich, Friedrich-Alexander Universität Erlangen-Nürnberg (FAU)

Date and Time: Tuesday, November 14, 2017 at 3:00PM-4:00PM

Location: DBH 4011


In this talk, we give an overview of novel techniques for systematically mapping applications to NoC-based multi-core architectures
(MPSoCs). Complex applications requiring heterogenous processing resources are often described by task graphs
with data dependencies. Here, the nodes represent actors or tasks which are typically activated periodically based on the
availability of data. One prominent domain of applications fitting this model is stream processing. Here, it is often important to guarantee
either bandwidth or execution time requirements. But more recently, also security, energy and reliability aspects impose
constraints on the mapping of the tasks as well as their communication to cores, respectively routes in the underlying NoC.

Concerning mapping methodologies, we first present a class of algorithms that perform “Self-Embedding”. The idea is here that
a source node issues a request to find appropriate resources to embed its sucessor tasks, and so on.
The next class of techniques introduced is called “Hybrid Application Mapping (HAM)”. Here, a careful analysis and
characterization of symmetric mappings by constellations of cores and routes is explored in a static (compile-time)
phase called “Design Space Exploration (DSE)”. At run-time, the operating system then only needs to search within such
pre-analysed constellations for finding a concrete mapping that will satisfy the given non-functional constraints by construction.
We present ideas of how timing constraints may be statically analysed in case of compositional MPSoC architectures such that
deadlines or throughput requirements will be automatically met for streaming applications.
Finally, we conclude with a discussion on resource constellations that may satisfy certain security requirements on an MPSoC.

Abstract: Multicore technology plays a pivotal role in conquering key societal challenges. For example, safe, ecological mobility, wide-spread rollout of eHealth, smart industrial automation and the development of a secure, high-bandwidth, low-latency mobile communication infrastructure for Industry 4.0, all these application domains are critically dependent on high-performance, low power and dependable computing. However, multicore technology also comes with a number of unique challenges for industry and academia. Today, the efficient utilization of massively parallel computing resources largely depends on the experience of individual programmers.

Application-specific accelerators and generic enablement building blocks for Multicore System on Chip (MCSoC) platforms are research foci at the Chair for Integrated Systems at TU München. These building blocks support a more performant, energy efficient, easier to use and more resilient deployment of multicore processors by application programmers and system integrators. In my talk, I will present current and past research projects on wire-speed traffic distribution among Software Defined Networking (SDN) nodes, interconnect virtualization for Network on Chip and processing node resilience, efficient multicore deployment in legacy automotive CAN networks and on-chip diagnosis for effective software debugging.

“Optimizing Private Local Memories in Heterogeneous Architectures”

Title: “Optimizing Private Local Memories in Heterogeneous Architectures”

Speaker: Christian Pilato, Università della Svizzera italiana (USI), Lugano, Switzerland

Date and Time: Wednesday, June 14, 2017 at 11:00AM-12:00PM

Location: ICS 432


Modern Systems-on-Chip (SoC) architectures and state-of-the-art computing platforms that integrate CPUs with FPGAs are heterogeneous systems featuring an increasing number of hardware accelerators. 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.

In 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.

Self-Awareness in Remote Health Monitoring Systems using Wearable Electronics

Title:  “Self-Awareness in Remote Health Monitoring Systems using Wearable Electronics”

Speaker: Prof. Axel Jantsch, TU Wien

Date and Time:  Friday,  June 16, 2017 at 11 A.M.

Location: 2430 Engineering Hall

Host: Prof. Nikil Dutt

Abstract: In healthcare, effective monitoring of patients plays a key role in detecting health deterioration early enough. 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

(i) situation awareness to consider the impact of variations such as sleeping, walking, running, and resting,

(ii) system personalization by reflecting parameters such as age, body mass index, and gender, and

(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.

Low Energy, a New Trend for Lightweight Cryptography

Title: “Low Energy, a New Trend for Lightweight Cryptography”

Speaker: Dr. Francesco Regazzoni, ALaRI Institute of Università della Svizzera italiana, Lugano, Switzerland

Date and Time:  Wednesday, February 1, 2017 at 11:00 a.m.

Location: DBH 4011

Host: Prof. Nikil Dutt

Abstract: In the last decade, several lightweight block ciphers and hash functions have been proposed. 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.

This 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.

The 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.

High Level Synthesis – Some Challenging Problems

Title: “High Level Synthesis – Some Challenging Problems”

Speaker: George A. Constantinides, Imperial College London, UK

Date and Time: Wednesday, November 16, 2016 at 11:00 A.M.

Location: Engineering Hall 2430

Host: Professor Nikil Dutt

Abstract: 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.

Malicious LUT: A Stealthy FPGA Trojan Injected and Triggered by the Design Flow

Title:  “Malicious LUT: A Stealthy FPGA Trojan Injected and Triggered by the Design Flow”

Speaker: Christian Krieg, Vienna University of Technology, Vienna, Austria

Date and Time: Thursday, November 17, 2016 at 2:00 PM

Location: Donald Bren Hall 3011

Host:  Professor Nikil Dutt

Abstract: We present a novel type of Trojan trigger targeted at the field-programmable gate array (FPGA) design flow. 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.

Biography: 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. His research focuses on design-level hardware Trojan design and detection. He also works on reasonable threat models for hardware Trojan attacks. Christian recently received the William McCalla best paper award for a novel hardware Trojan implementation.

Time:  3:00PM

Location:  Harut Barsamian Colloquia Room (Engineering Hall 2430)

Host: Prof. Payam Heydari

Abstract: In this talk, we will discuss variability challenges in VLSI systems and our recent research efforts on variation-adaptive design techniques. 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-situ, 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-situ aging monitoring in pipeline and SRAM register files. Several test chip measurement results will be presented.
