Design-Technology Co-Optimization for NVM-based Neuromorphic Processing Elements

no code implementations10 Mar 2022 Shihao Song, Adarsha Balaji, Anup Das, Nagarajan Kandasamy

First, on the technology front, we propose an optimization scheme where the NVM resistance state that takes the longest time to sense is set on current paths having the least delay, and vice versa, reducing the average PE latency, which improves the QoS.

A Design Flow for Mapping Spiking Neural Networks to Many-Core Neuromorphic Hardware

no code implementations27 Aug 2021 Shihao Song, M. Lakshmi Varshika, Anup Das, Nagarajan Kandasamy

We propose an SDFG-based design flow for mapping spiking neural networks (SNNs) to many-core neuromorphic hardware with the objective of exploring the tradeoff between throughput and buffer size.

Dynamic Reliability Management in Neuromorphic Computing

no code implementations5 May 2021 Shihao Song, Jui Hanamshet, Adarsha Balaji, Anup Das, Jeffrey L. Krichmar, Nikil D. Dutt, Nagarajan Kandasamy, Francky Catthoor

We propose a new architectural technique to mitigate the aging-related reliability problems in neuromorphic systems, by designing an intelligent run-time manager (NCRTM), which dynamically destresses neuron and synapse circuits in response to the short-term aging in their CMOS transistors during the execution of machine learning workloads, with the objective of meeting a reliability target.

NeuroXplorer 1.0: An Extensible Framework for Architectural Exploration with Spiking Neural Networks

no code implementations4 May 2021 Adarsha Balaji, Shihao Song, Twisha Titirsha, Anup Das, Jeffrey Krichmar, Nikil Dutt, James Shackleford, Nagarajan Kandasamy, Francky Catthoor

Recently, both industry and academia have proposed many different neuromorphic architectures to execute applications that are designed with Spiking Neural Network (SNN).

Endurance-Aware Mapping of Spiking Neural Networks to Neuromorphic Hardware

no code implementations9 Mar 2021 Twisha Titirsha, Shihao Song, Anup Das, Jeffrey Krichmar, Nikil Dutt, Nagarajan Kandasamy, Francky Catthoor

We propose eSpine, a novel technique to improve lifetime by incorporating the endurance variation within each crossbar in mapping machine learning workloads, ensuring that synapses with higher activation are always implemented on memristors with higher endurance, and vice versa.

Improving Dependability of Neuromorphic Computing With Non-Volatile Memory

no code implementations10 Jun 2020 Shihao Song, Anup Das, Nagarajan Kandasamy

We evaluate RENEU using different machine learning applications on a state-of-the-art neuromorphic hardware with NVM synapses.

Compiling Spiking Neural Networks to Neuromorphic Hardware

1 code implementation7 Apr 2020 Shihao Song, Adarsha Balaji, Anup Das, Nagarajan Kandasamy, James Shackleford

First, we propose a greedy technique to partition an SNN into clusters of neurons and synapses such that each cluster can fit on to the resources of a crossbar.

A New Approach to Dimensionality Reduction for Anomaly Detection in Data Traffic

no code implementations14 Jun 2016 Tingshan Huang, Harish Sethu, Nagarajan Kandasamy

This variance-based subspace approach to dimensionality reduction forces a fixed choice of the number of dimensions, is not responsive to real-time shifts in observed traffic patterns, and is vulnerable to normal traffic spoofing.
