Introduction to Large-Scale Neuromorphic Systems

Neuromorphic engineering has been studied for the last few decades as a way to mimic biological systems by using electronics. Many researchers have used electronics to demonstrate various systems mimicking neural and synaptic dynamics. In this article, we introduce the idea of neuromorphic engineering from the viewpoint of circuits and systems design. We explain spiking neural networks, which are run on neuromorphic systems. We introduce the principle components of neuromorphic system design, such as neuron and synapse circuits. In addition, we introduce various large-scale neuromorphic systems that have been developed by various worldwide neuromorphic research groups.
