“Making Sense of the Data Trove Hidden in Medical Ultrasound Signals”

Résumé - This talk focuses on developing image analysis techniques that reveal otherwise hidden information in clinical ultrasound Signals. Ultrasound is one of the most commonly used imaging modalities because of its low cost and ease of use. However, it has two main drawbacks. First, raw ultrasound data is not suitable for visualization, and as such, is converted to the familiar grey-scale images which lead to a loss of most of its information. Second, these grey-scale images are hard to interpret since they are noisy and collected at oblique angles. In this talk, we tackle these issues by developing techniques that extract clinically useful information such as tissue elasticity from the complex raw ultrasound signals, and register them to other modalities such as Magnetic Resonance Imaging (MRI) to help with their interpretation.

“IoT Edge Computing using Emerging Technologies”

Résumé - The current trend in the Internet of Things (IoT) is to design processing subsystems on the edge that are smarter, smaller and more autonomous. Therefore, it is expected that the Internet of Things of the future will not be composed of passive devices sending data to a server, it will be rather like a distributed computing fabric, where many of the IoT devices and subsystems themselves will process and analyze the data and make autonomous processing. Typical target applications include video-processing systems of smart cars, video surveillance cameras, mobile phones, home personal assistants, drones, healthcare devices, industrial monitoring, and control, etc. Moving intensive computation to the end-points promises multiple benefits for IoT applications: low latency, reduced bandwidth requirements, as well as improved privacy, security, and reliability. These benefits are crucial for mission-critical IoT applications. These will go beyond the current critical applications in the healthcare, industrial, and power systems industries. They are evolving to encompass a new breed of applications that are required to work as anticipated, without failure, every time, in industries like wearables, smart city, smart home, and others.

The key enablers for this new paradigm will be the innovative programmable devices and subsystems able to execute multiple complex algorithms, under tight timing and power constraints. The current requirements are very high: up to 10 Tera Operations Per Second (TOPS) per Watt. These new challenges demand innovation in the design process through new architectures based on emerging technologies and new system-level methods enabling designers to take advantages from the new architectures.  In this presentation, we will discuss architecture-level and system-level innovative solutions for future intensive computation at the edge of IoT.

“Adaptive and Resilient Circuits for Processors”

Résumé - Dynamic device, circuit, and system parameter variations degrade processor performance, energy efficiency, and yield across all market segments, ranging from small embedded cores in an Internet of Things (IoT) device to large multicore servers.  This lecture introduces the primary variations during the processor operational lifetime, including supply voltage drops, temperature changes, transistor and interconnect aging, radiation-induced soft errors, and workload fluctuations.  This presentation then describes the negative impact of these variations on processor logic and memory across a wide range of voltage and clock frequency operating conditions.  To mitigate the adverse effects from dynamic variations, this lecture presents adaptive and resilient circuits while highlighting the key design trade-offs and testing implications for product deployment.

“Energy Effective Graphene Based Computing”

Résumé - In this presentation, we argue and provide Non-Equilibrium Green’s Function Landauer formalism-based simulation evidence that in spite of Graphene’s bandgap absence, Graphene Nanoribbons (GNRs) can provide support for energy effective computing.  We start by demonstrating that: (i) band gap can be opened by means of GNR topology and (ii) GNR’s conductance can be mold according to some desired functionality, i.e., 2- and 3-input AND, NAND, OR, NOR, XOR, and XNOR, via shape and electrostatic interaction. Afterward, we introduce a generic GNR based Boolean gate structure composed of a pull-up GNR performing the gate Boolean function and a pull-down GNR performing the gate inverted Boolean function, and, by properly adjusting GNRs' dimensions and topology, we design and evaluate by means of SPICE simulations inverter, buffer, and 2-input GNR based AND, NAND, and XOR gates. When compared with state-of-the-art graphene FET and CMOS based counterparts the GNR-based gates outperform its challenges, e.g., up to 6x smaller propagation delay, 2 orders of magnitude smaller power consumption, while requiring 1 to 2 orders of magnitude smaller active area footprint than 7nm CMOS equivalents. Finally, to get better inside in the practical implications of the proposed approach, we present Full Adder (FA) and SRAM cell GNR designs, as they are currently fundamental components for the construction of any computation system. For an effective FA implementation, we introduce a 3-input MAJORITY gate, which apart of being able to directly compute FA's carry-out is an essential element in the implementation of Error-Correcting Codes codecs, that outperforms a 7nm CMOS equivalent Carry-Out calculation circuit by 2 and 3 orders of magnitude in terms of delay and power consumption, respectively, while requiring 2 orders of magnitude less area. The proposed FA exhibits 6x smaller delay, 3 orders of magnitude less power consumption, while requiring 2 orders of magnitude less area than a 7 nm FinFET CMOS counterpart. However, because of the effective carry-out circuitry, a GNR-based n-bit Ripple Carry Adder, whose performance is linear in the Carry-Out path delay, will be 108x faster than an equivalent CMOS implementation. The GNR-based SRAM cell provides a slightly better resilience to DC-noise characteristics, while performance-wise has a 3x smaller delay, consumes 2 orders of magnitude less power, and requires one order of magnitude less area than the CMOS equivalent. These results clearly indicate that the proposed GNR-based approach is opening a promising avenue towards future competitive carbon-based nanoelectronics.
