Performance and Energy Simulation of Spiking Neuromorphic Architectures for Fast Exploration

Boyle, James; Plagge, Mark P.; Cardwell, Suma G.; Chance, Frances S.; Gerstlauer, Andreas

Recent work in neuromorphic computing has proposed a range of new architectures for Spiking Neural Network (SNN)-based systems. However, neuromorphic design lacks a framework to facilitate exploration of different SNN-based architectures and aid with early design decisions. While there are various SNN simulators, none can be used to rapidly estimate latency and energy of different spiking architectures. We show that while current spiking designs differ in implementation, they have common features which can be represented as a generic architecture template. We describe an initial version of a framework that simulates a range of neuromorphic architectures at an abstract time-step granularity. We demonstrate our simulator by modeling Intel's Loihi platform, estimating time-varying energy and latency with less than 10% mean error for various sizes of a two-layer SNN.
