DISTINGUISHED LECTURE at the ECE SEMINAR SERIES
Spiking Neural Networks (SNNs) have emerged as an alternative to deep learning especially for edge computing due to their huge energy efficiency benefits on neuromorphic hardware. In this presentation, I will discuss the roadmap of current activities in the SNN algorithm and hardware design space, especially in reference to compute-in-memory accelerators.
In the first half, I will talk about the importance of temporal dimension in SNNs which unlock unique behavior such as, robustness and bring in huge benefits in terms of latency, energy, and accuracy in different applications like video segmentation, human activity recognition, event sensing among others. In the second half, I will delve into the hardware perspective of SNNs when implemented on compute-in-memory (CiM) accelerators with our recently proposed SpikeSim benchmarking tool. It turns out that the multiple timestep computation in SNNs can lead to extra memory overhead and exacerbates the effect of CiM non-idealities that annuls all the compute-sparsity related advantages. I will highlight some techniques such as, input-aware early time-step exit and temporally evolving batch normalization to reduce the overhead. Finally, I will discuss a future landscape of CiM device-circuit-system co-design for SNNs that includes investigating emerging devices for reducing on-chip memory for neuronal computations and efficient dot-product implementations.
