Hi,

On table 2 of the Davies, et. all paper, “Loihi: A Neuromorphic Manycore Processor with On-Chip Learning,” there is a listing of simulated energy consumption on Loihi. Not being an expert on hardware design, can somebody help me determine how, given a graph, to roughly calculate projected energy usage? Ie: solve energy = f(N_neurons, N_spiking_connections, N_graded_connections, N_spikes, time_active_per_non_spiking_neuron, N_learning_rule_updates).

I see that energy linearly increases with the number of synapse updates, neuron updates, and number of spikes, but I am more fuzzy on the “tile hops” and tiles.

Thanks for your help!
