However, the unique features of SNN hardware have not been fully exploited, where the computation speed and energy efficiency of the SNN hardware can be improved. Firstly, this thesis presents a low-power and low-area router with a congestion-aware routing algorithm for SNN hardware. The fabricated router chip consumes 0.08 mW at 0.80 V, including IO pads and other peripherals. Secondly, this thesis proposes two versions of SNN hardware (Novena 1 and Novena 2). At 0.5 V, the measured leakage of Novena 1 chip is only 0.93 μW/core, and the energy efficiency is 4.8 pJ/SOP. In order to improve the processing speed and energy efficiency of the neuron core, this thesis proposes Novena 2, which achieves ultra-low energy consumption of 4.5 pJ/SOP. Finally, we present a low-cost, high-throughput digital hardware design for the Izhikevich model. | URI: | https://hdl.handle.net/10356/159982 | DOI: | 10.32657/10356/159982 | Schools: | School of Electrical and Electronic Engineering | Rights: | This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License (CC BY-NC 4.0). | Fulltext Permission: | open | Fulltext Availability: | With Fulltext |
