Computing

C1 – Spatio-Temporal Neural Filtering and Processing for Smart Camera Platform

Avik Ghosh (UVA) and Mircea Stan (UVA)

Develops a unified platform for smart camera signal processing architecture consisting of Reservoir Computing based neuro-adaptive filters coupled with a hybrid Convolutional Neural Networks and Hierarchical Temporal Memory (CNN-HTM) based learning and inferencing network that can learn, predict and detect user defined features from the camera’s noisy imaging data in real time.

C2 – Hybrid Topological Insulator-ferromagnet Stackers for In-memory Computing

Avik Ghosh (UVA)

Explores the interaction between a ferromagnet (FM) and a topological insulator (TI) as a means to design an in-memory computing element. This element will (a) use TIs to write information onto a magnetic tunnel junction read unit, and (b) use a separate magnet to open and close a TI gap. The former will be used at a single bit cell level for efficient switching, while the latter will be used at the architecture level for row-column selection, much like a 1T-1C DRAM.

C3 – Interoperable Emerging Memory Technology (EMT)
emulation platform

Mircea Stan (UVA) and Kevin Skadron (UVA)

The main goal of this project is to continue adding memory model support to the Emerging-Memory
Technology (EMT) emulation platform developed at the University of Virginia. Additionally, a secondary
goal is to continue porting UVA’s existing platform from Xilinx to an Intel/Altera platform. Finally, a third goal is to create an API for using the EMT emulation platform with architecture level simulators such as GEM5 and/or SST.

Integration

I1 – Spectroscopy Investigations of Sn Resonant Doping in Bi2Se3

Stephen McDonnell (UVA)

Demonstrates control of the Fermi level position in
topological insulators (TI’s) such as Bi2Se3 using Sn as a resonant dopant to enable ultra-low power electronics. It also has the additional potential to boost this material’s thermoelectric performance.

I2 – Flexible Smart-Substrate Hybrid Electronics

Hugh Fan (UF) and Toshi Nishida (UF)

Development of the large area strain and temperature sensors on the flexible substrate through additive manufacturing approaches provides technologies for enabling high volume manufacturing. This method would also improve the packaging of sensors and increasing the variety of sensors that can be assembled on a single platform.

Sensing

S1 – Flat-Packaged Optical Pressure Sensor for Extreme Temperature Environments

Mark Sheplak (UF)

Develops time-resolved dynamic pressure sensing technology for high-temperature (>1000 °C) applications in the aerospace, energy, and automotive sectors. A flat-packaged design will extend the applicability of this sensor to thin-wall locations

S2 – 3D Microelectrode Arrays (3D MEAs) for Zebrafish Cardiac Measurements

Swaminathan Rajaraman (UCF)

Develops a polymer-3D microneedle-based micromachining technology for a 3D Microelectrode Array (3D MEA) to interface directly with zebrafish heart for cardiac measurements in vivo at the sponsor.
