ECE SEMINAR: In-Memory Computing: from Devices to Applications - A Cross-Layer Perspective
This event has passed.

X. Sharon Hu, Professor, Department of Computer Science and Engineering, University of Notre Dame
Data transfer between processors and memory is a major bottleneck in improving application performance on traditional computing hardware. This is particularly true for data intensive workloads such as many machine learning, bioinformatics and security applications. In-memory computing (IMC), where significant amount of data processing is performed directly in memory, can be an effective alternative to address this bottleneck. However, due to the myriad of design options for an IMC based solution, harnessing the benefits of the IMC paradigm requires cross-layer efforts spanning from devices and circuits to architectures and systems.
This talk will showcase several representative cross-layer IMC based design efforts. In particular, the talk will highlight how different non-volatile device technologies (such as RRAM, FeFET memory and Flash) can be exploited to implement various IMC functions (e.g., exact and best match for associative search, configurable look-up tables, etc.), and what are some unique challenges in designing IMC circuits and architectures. IMC solutions for several popular machine learning and other applications will be analyzed end-to-end to reveal the benefits contributed by each design layer, which can serve as guides for future research efforts.
