Congratulations to Aqeel Anwar

Congratulations to Aqeel Anwar

Aqeel Anwar, a Ph.D. student in the Georgia Tech School of Electrical and Computer Engineering (ECE), won the Best Student Paper Award at the 2018 IEEE Mechatronics and Machine Vision in Practice (M2VIP), held November 20-22 in Stuttgart, Germany. He is advised by ECE Associate Professor Arijit Raychowdhury and is a member of the Integrated Circuits and Systems Research Lab.

Anwar’s paper is titled "NAVREN-RL: Learning to Fly in Real Environment via End-To-End Deep Reinforcement Learning Using Monocular Images". The paper focuses on the challenges posed by the implementation of Reinforcement Learning (RL) for the autonomous navigation of low cost drones in real environments without incurring any extra hardware cost.

In recent years, RL has been extensively explored for different type of robotic tasks. All of these previous demonstrations and approaches, in spite of their many successes, either require considerable human intervention, handcrafted algorithms or are implemented offline in simulations, where the simulated and the real endowments need to be nearly identical. This work proposes an end-to-end approach for drone navigation addressing the challenges for real environments. A suitable reward function is designed keeping in mind the cost and weight constraints for micro drone with minimum number of sensing modalities. Collection of small number of expert data and knowledge based data aggregation is integrated into the RL process to aid convergence. Experimentation is carried out on a Parrot AR drone in different indoor arenas and the results are compared with other baseline technologies. We demonstrate how the drone successfully avoids obstacles and navigates across different arenas. Video of the drone navigating using the proposed approach can be seen here.

This work is supported by the SRC and DARPA sponsored Center for Brain-inspired Computing Enabling Autonomous Intelligence. As a part of this project, Aqeel and his colleagues in ICSRL are exploring hardware designs and architectures to enable ubiquitous intelligence from autonomous edge devices to the cloud.

Congratulations to Hakki Mert Torun

Congratulations to Hakki Mert Torun

Congratulations to Hakki Mert Torun on winning the Best Student Paper Award at the IEEE 27th Conference on Electrical Performance of Electronic Packaging and Systems. The conference was held October 14-17 in San Jose, California.
The title of Hakki’s award-winning paper is "Bayesian Active Learning for Uncertainty Quantification of High-Speed Channel Signaling.” His coauthors on the paper are his Ph.D. advisor, Madhavan Swaminathan, and Jose Hejase, Junyan Tang, and Dale Becker – all of IBM. 
Increasing data rates in server high-speed communication busses, such as in cloud data centers, makes their electrical performance more susceptible to uncertainties in manufacturing processes. As a result, it is essential to understand channel design limitations and performance under tolerances to ensure a robust system. However, predicting channel performance under tolerances can become very straining in time, effort, and computational resources. To address this, Hakki and his colleagues present a new technique based on Bayesian Active Learning that automatically builds a predictive model from scratch, hence, does not require prior training data. While deriving the model, the presented algorithm simultaneously finds the worst case scenario to ensure channel compliancy and ranks the expected manufacturing tolerances in terms of their effect on electrical performance. The results show that the presented method provides a higher model accuracy in less CPU time compared to state-of-the-art methodologies and requires minimal human intervention.

Congratulations to Muhannad Bakir

Congratulations to Muhannad Bakir 

Congratulations to Muhannad Bakir and his colleague Sam Sober at the Department of Biology at Emory University on receiving a McKnight Technological Innovation in Neuroscience Award. This marks the first time that Georgia Tech has received this prestigious honor. Out of 112 submissions, their project was one of three awarded by the McKnight Foundation. Each of the projects recognized in the program will be aimed at developing groundbreaking technologies to map, monitor, and model brain function. 
The title of Muhannad's and Sam’s project is “Flexible electrode arrays for large-scale recordings of spikes from muscle fibers in freely behaving mice and songbirds.” They are developing a high definition sensor array that allows researchers to detect and record very precise electrical signals from individual muscle fibers. To date, this information has been gathered by inserting wires into muscles that can only detect the summed activity of many individual signals that the nervous system uses to control muscles. The proposed approach has many electrode arrays that record from a muscle without damaging it. Prior approaches relied on wires that could damage muscles when inserted, especially small muscles used in fine motor skills. The arrays are fabricated from flexible materials that fit the shape of a muscle and change shape as the animal moves. Because the arrays collect exponentially more data than prior devices, they have built-in 3D stacked circuits to collect and serialize the data before transmitting the signals to the researcher’s computer; to enable such compact and very dense electrode arrays, 3D IC technology, advanced microelectronic packaging, and flexible electronic technologies are all utilized and co-integrated.   
A previous prototype version of the array has already revealed new insights. Previously, it was believed that the nervous system controls muscle activity by regulating only the total number of electrical spikes sent to a muscle. But precise detection done by the Emory team revealed that millisecond-level variations in multi-spike timing patterns change how muscles control behavior. The new arrays will be designed for use in mice and songbirds and will help the team understand the neural control of many different skilled behaviors and potentially provide new insights into neurological disorders that affect motor control.

Arijit Raychowdhury awarded "Innovator Under 40 Award"

Arijit Raychowdhury awarded "Innovator Under 40 Award"

Congratulations to Arijit Raychowdhury on being awarded the IEEE/ACM "Innovator Under 40 Award" at the Design Automation Conference this year. The award is intended for specific contributions such as commercial products, software or hardware systems, or specific algorithms or tools incorporated into other systems widely used by industry and academia.  The impact is measured by commercialization and wide adoption of the nominee’s contributions.
Arijit won the award for his contributions to "integrated DSL Modems, always-on and intelligent sensor hardware and model development for non-linear control in voltage regulators.”
Prior to attending graduate school, Arijit first worked as an analog researcher at Texas Instruments (TI) for two years, where he designed the world's first adaptive mixed-signal echo-canceller for the receive-channel in ADSL modems. It used a hardware based optimizer for impedance matching and resulted in 1.5X range improvement. Arijit holds two key patents in this area and the design eventually was adopted by three generations of TI modems and was awarded the EDN design of the year award.
After receiving his Ph.D., Arijit joined Intel Labs as a research scientist where he led the design of "always-on" smart microphones, which led to a design win with BMW and led to the adoption of the technology in automotive infotainment systems. This was the industry's first hardware design that incorporated an ultra-low power microphone-sensor front-end with a fully-programmable keyword-spotting hardware.
Since joining Georgia Tech in 2013, Arijit has been exploring various aspects of power-efficient design. Most notably, his students and he contributed to the development of switched-mode and non-linear control in high-bandwidth all-digital, linear regulators – that have gained wide traction with the semiconductor companies. The design principles have been adopted in internal test-chips and system prototypes at Qualcomm and Intel.
Arijit was nominated for the award by researchers and engineers from Qualcomm, TI, TSMC, and Intel with support from Georgia Tech and the University of California, Berkeley.

Tom Sarvey Receives 2017 Best Paper Award for the IEEE Transactions on Components, Packaging, and Manufacturing Technology

Congratulations to Tom Sarvey on receiving the 2017 Best Paper Award for the IEEE Transactions on Components, Packaging, and Manufacturing Technology in the Components: Characterization and Modeling category. He will be recognized for the paper entitled "Monolithic Integration of a Micropin-Fin Heat Sink in a 28-nm FPGA” at the 2018 IEEE Electronic Components and Technology Conference. The conference will be held May 29-June 1 in San Diego, California.  

This marks the second time that a member of the Integrated 3D Systems (I3DS) Group has won this particular Best Paper Award. Tom is a Ph.D. student in the I3DS Group, which is led by Muhannad Bakir. Tom’s coauthors on the paper are Yang Zhang, an alumnus of the group; Dr. Bakir; and Colman Cheung, Ravi Gutala, Arifur Rahman, and Aravind Dasu, all of Intel Corporation’s Programmable Solutions Group. For more than a decade, the challenge of removing the heat from high end computing platforms has been a primary limiter of processor power and computing performance. The use of micro-scale fluidic channels has previously been proposed as a method of extracting the large amounts of heat produced by modern processors. In this work, such a liquid-cooled heat sink was etched into the backside of a field programmable gate array (FPGA) die, approximately 500 μm from the heat generating circuitry. The heat sink, only 240 μm tall, provided a thermal resistance that is approximately one quarter of that of the best air-cooled heat sinks, in less than 1/1000th of the volume. This type of cooling has the potential to unlock higher computing throughput, lower energy usage, and denser integration in datacenters and high performance computing applications.

Professor Hua Wang to Lead Research on Wideband Amplifiers with DARPA Young Faculty Award

Professor Hua Wang has received a DARPA Young Faculty Award for his research project entitled “MAXIMA: Multi-Mode Hybrid Power Amplifier with EXtreme Instantaneous Bandwidth and Recursive Scalable Marchand-Doherty Load ModulAtion Network.” The DARPA YFA program aims to identify and engage rising stars in junior faculty positions in academia and equivalent positions at non-profit research institutions and expose them to Department of Defense and National Security challenges and needs.

As millimeter-wave frequency applications have become prevalent in the commercial and DoD markets, there is a rapidly growing need for advanced millimeter-wave solid-state power amplifier technologies that can support high energy efficiency, sufficient output power, and high-speed complex modulations. Moreover, high-efficiency amplifiers covering extremely wide bandwidth have become a necessity, particularly for frequency-agile massive Multiple-Input-Multiple-Output (MIMO) systems, such as multi-standard 5G wireless communication.

In this project, Hua will lead the fundamental research on a completely new class of extremely-wideband-yet-efficient power amplifiers, known as Multi-Mode Hybrid Power Amplifiers with EXtreme Instantaneous Bandwidth and Recursive Scalable Marchand-Doherty Load ModulAtion Network (MAXIMA). The key technology innovations include novel amplifier circuit topologies, hybrid use of silicon/non-silicon solid-state devices, and multi-mode amplifier operations. This project will potentially achieve a new class of load modulation power amplifiers with an unprecedented combination of bandwidth, energy efficiency, and output power. Such amplifier technologies will eventually enable true “common-module front-ends” for reconfigurable transmitters and MIMO systems with "full-spectrum access" and digital beamforming for wireless communication, radar, imaging, and spectrum sensing applications.

EDA’s CAEML Grows More Humps: Al Expands Role in Design

The use of AI in EDA is a hot topic due to significant progress with applying machine learning to the issues of chip design.

Over the past year, the Center for Advanced Electronics through Machine Learning (CAEML) has gained four new partners. The team of 13 industry members and three universities has expanded both the breadth and depth of its work. CAEML is funded in part by a National Science Foundation program. In the past, CAEML focused on signal integrity and power integrity, but this year, the team has diversified its portfolio with system analysis, chip layout and trusted platform design.

“One of the challenges we face is getting access to data from companies,” said Professor Madhavan Swaminathan, the John Pippin Chair in Microsystems Packaging & Electromagnetics and Director of Center for Co-Design of Chip, Package, System (C3PS) at the Georgia Institute of Technology, a CAEML host. “Most of their data is proprietary, so we’ve come up with several mechanisms to handle it. The processes are working fairly well, but they are more lengthy than we’d like.”

Previously, the group had a sort of coming-out party. It started with backing from nine vendors including Analog Devices, Cadence, Cisco, IBM, Nvidia, Qualcomm, Samsung, and Xilinx. Its initial interest areas included high-speed interconnects, power delivery, system-level electrostatic discharge, IP core reuse, and design rule checking.

After this year, it is clear that the EDA industry is entering its second phase in its use of AI (moving past high-speed interconnects, power delivery etc. and into the realm of machine learning), which the next phase of product development in optimizations that speed turnaround time. Often hindered by current algorithmic limitations.

Researchers are exploring opportunities to replace today’s simulators with AI models (faster) after a reported 40 MHz increase in speed last year. "Relatively slow simulators can lead to timing errors, mistuned analog circuits, and insufficient modeling that results in chip re-spins, said Swaminathan. In addition, machine learning can replace IBIS for behavioral modeling in high-speed interconnects."

Chip researchers are currently combatting the issue with research in data mining, surrogate models, statistical learning, and neural networking models (used by Amazon, Google etc).

“The amount of training data required is high,” said Christopher Cheng of Hewlett-Packard Enterprise, another member of the CAEML team. “Classifiers are static, but we want to add the dimension of time using recurrent neural networks to enable time-to-failure labels. We want to extend this work to more parameters and general system failures in the future.”

Georgia Tech’s Center for Co-design of Chip, Package System (C3PS) partners with Notre Dame in $26 million multi-university research center developing next-generation computing technologies

In today’s era of big data, cloud computing, and Internet of Things devices, information is produced and shared on a scale that challenges the current processing speeds and energy load demands placed on electronics devices. These challenges are only set to expand, as the ability to create and store data increases in magnitude over the next decade.

With these computing challenges in mind, the Semiconductor Research Corporation's (SRC) Joint University Microelectronics Program (JUMP), which represents a consortium of industrial participants and the Defense Advanced Research Projects Agency (DARPA), has established a new $26 million center called the Applications and Systems-driven Center for Energy-Efficient integrated Nano Technologies (ASCENT).

Georgia Tech’s Center for Co-design of Chip, Package System (C3PS) led by Profs. A. Raychowdhury and M. Swaminathan, deputy director and director, respectively, both from the School of Electrical and Computer Engineering, and with support from the Institute of Electronics and Nanotechnology, headed-up Georgia Tech’s winning proposal that resulted in a 5 year, $3.5M award that will fund up to 10 GRA positions.

The multidisciplinary, multi-university center will focus on conducting research that aims to increase the performance, efficiency and capabilities of future computing systems for both commercial and defense applications. By going beyond current industry approaches, such as two dimensional scaling and the addition of performance boosters to complementary metal oxide semiconductors, or CMOS technology, the GT team seeks to provide enhanced performance and energy consumption at lower costs.

Profs. Raychowdhury (PI) and Swaminathan (co-PI) will work in the area of heterogeneous integration, with a focus on the design of high speed die-to-die networks, the incorporation of power, logic, memory and RF components on a common substrate that enables 2.5D and 3D integration.

“Our involvement in the ASCENT center provides us with unique opportunities to partner with the academic and industrial leaders to explore foundational technologies in computing. We will leverage our expertise on high-speed circuit design, device-circuit interactions and advanced packaging to address logic and memory challenges for next-generation computing and communication systems,” said Prof. Raychowdhury, the ON Semiconductor Jr. Associate Professor of VLSI Systems.

“Georgia Tech has always had a long history of working with SRC and we are therefore excited and honored to continue that effort through JUMP,” said Prof. M. Swaminathan, John Pippin Chair in Microsystems Packaging & Electromagnetics and C3PS director. “Through JUMP we plan on expanding our current center capabilities on power delivery, machine learning, multi-physics simulation and system design to include new circuit architectures, power converters, magnetic materials, high frequency components, vertically integrated tools and other platform technologies on a common interconnect fabric.”

This is one of the largest JUMP centers funded by SRC and will work synergistically over the next five years to provide breakthrough technologies.  Other universities involved in the 13-member team include; Notre Dame (lead), Arizona State University, Cornell University, Purdue University, Stanford University, University of Minnesota, University of California-Berkeley, University of California-Los Angeles, University of California-San Diego, University of California-Santa Barbara, University of Colorado, and the University of Texas-Dallas.

Tushar Krishna Receives NSF CISE Research Initiation Initiative Award

Congratulations to Professor Tushar Krishna, ECE & C3PS, on receiving an NSF CISE Research Initiation Initiative Award. The title of his research project is “Enabling Neuroevolution in Hardware” and will be two years in duration.

Over the past few years, machine learning algorithms, especially neural networks (NN) have seen a surge of popularity owing to their potential in solving a wide variety of complex problems across image classification and speech recognition. Unfortunately, in order to be effective, NNs need to have the appropriate topology (connections between neurons) for the task at hand and have the right weights on the connections. This is known as supervised learning and requires training the NN by running it through terabytes to petabytes of data. This form of machine learning is infeasible for the emerging domain of autonomous systems (robots/drones/cars) which will often operate in environments where the right topology for the task may be unknown or keep changing, and robust training data is not available. Autonomous systems need the ability to mirror human-like learning, where we are continuously learning, and often from experiences rather than being explicitly trained. This is known as reinforcement learning.

The focus of this research will be on neuroevolution (NE), a class of reinforcement learning algorithms that evolve NN topologies and weights for the task at hand using evolutionary algorithms. The goal of this project will be on enabling NE in energy-constrained autonomous devices by leveraging opportunities for parallelism and hardware acceleration. If successful, this research can enable mass proliferation of autonomous drones and robots that can learn to perform tasks without being explicitly trained.

When augmented with traditional transistor technology (HyperFETs), phase transition devices can enable a vast class of computing primitives, from better transistors to oscillators and spike generators. Arijit and his colleagues have demonstrated through theory and experiments how HyperFETs can impact power efficiency of a class of computing architectures and applications. This work is currently being extended and explored in collaboration with Intel Corporation.

Arijit is currently the ON Semiconductor Associate Professor of ECE and leads the Integrated Circuits and Systems Research Lab. His students and he are exploring power-efficient circuits topologies and the corresponding computing models that can enable the next generation of low-power autonomous systems.

GT Team Looks to the Future of CHIPS with DARPA Program

A team of Georgia Tech researchers is bringing electronic design software and communications expertise to DARPA's new CHIPS initiative, which will enable future generations of integrated circuits to be assembled from plug-and-play modules known as “chiplets.” Reusing blocks of existing microelectronics technology could reduce the need to design complex monolithic chips from scratch for new applications.

“The goal of this program is to make the design more modular so we can reuse existing components, making the design process much faster, easier and cheaper,” said Sung Kyu Lim, a School of Electrical and Computer Engineering professor who heads up Georgia Tech’s part of the initiative. “We’ll be able to create new chips to meet specific needs by reusing these chiplets and putting them together in modular fashion. The modular design will allow us to pick and choose the components we need for specific applications.”

The four-year CHIPS effort involves 11 teams, including major defense contractors, microelectronics companies, design firms – and two other universities: the University of Michigan and North Carolina State University. In addition to Lim, the Georgia Tech effort will involve three other faculty members: Pippin Chair Professor Madhavan Swaminathan, Professor Saibal Mukhopadhyay and Assistant Professor Tushar Krishna, all from the School of Electrical and Computer Engineering.

Side-Channel Protection Research Scores Best Student Paper Award from IEEE - HOST

Saad Bin Nasir’s research into side-channel attack protection won the Best Student Paper Award at the 2017 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), held May 1-5, 2017, in McLean, Virginia. This work is done in collaboration with the SPARC Lab, Purdue University (co-authors Debayan Das, Shovan Maity, and Shreyas Sen), and the Emerging Security Lab at Intel.

Saad is advised by ECE Associate Professor Arijit Raychowdhury. The paper is titled "High Efficiency Power Side-Channel Attack Immunity using Noise Injection in Attenuated Signature Domain”. Side-Channel Attacks (SCA) focus on measuring physical side-channel information leaked from computationally secure cryptographic engines to attack and expose a secret key. Power Side-Channel uses the power/current consumption of the cryptographic IC. This work proposes embedding the cryptographic engine in signature-attenuating dual-loop hardware (a novel shunt low-dropout regulator, LDO based on Switched Mode Control), along with tiny noise injection to demonstrate highly efficient protection against Power SCA. Modeling, test-chip development and testing were carried out in 130nm CMOS technology
