“…While SNNs have gathered siginiicant research interest as promising bio-inspired models of computation, only a very few works have been done on SNN hardware accelerators [15,24,38,39,45], particularly array-based accelerators [1,6,23,49,52] due to the fact that the spatiotemporal nature of the spikes make it diicult to design an eicient architecture. Importantly, these limited existing works have primarily focused on feedforward SNNs where there exist very limited works that are capable of executing R-SNNs [2,17,37].…”
