Synthesis and implementation of digital spiking neurons
Tomoki Harada, Toshimichi Saito (HU) CCS2020-18
Abstract (in Japanese) (See Japanese page) 
(in English) This paper studies implementation of desired digital spike-trains based on simple evolutionary algorithm.
First, the dynamics of spike-trains is visualized by a digital spike map. The map is defined on a set of points
and is represented by a characteristic vector of integers. Second, the simple evolutionary algorithm is based on the
greedy searth. This algorithm aims at optimization of characteristic vector for cost function. We use autocorrelation
function as cost function. Third, in order to implement the digital spike map, we introduce a digital spiking neuron.
Repeating integrate-and-fire behavior between a periodic base signal and constant threshhold, the neuron can out
put various periodic spike-trains. Spike-trains are simulated by Verilog and the digital spiing neuron is implemented
by FPGA .
