UoA Competitive Research Funding (Ref. 2023-26): Low-power Spiking Neural Network Solution for IoT and Edge devices (2023-2024)

Project Summary

In this project, we develop a low-power solution for spiking neural networks using stacking 3D memory. Here, we split the weight of N-bit into several subsets and each subset is put into separated layers. We apply power-gating (dynamic quantization) or voltage scaling for LSBs to reduce the power consumption.

This project is funded by UoA Competitive Research Funding in AY 2023.
