Implementation of Desired Digital Spike Maps in the Digital Spiking Neurons
This paper considers implementation of desired digital spike maps (DSmaps) in the digital spiking neurons (DSNs). The DSmap is defined on a set of points and can describe various spike-trains. The DSN is constructed by two shift registers and a wiring. Depending on the wiring pattern, the DSN can generate various spike-trains. We present a simple formula that clarifies relation between the DSmaps and DSNs. Using the formula, desired DSmaps can be implemented in DSNs. We then present a simple ring-coupled system of the DSNs and demonstrate multi-phase synchronization of periodic spike-trains in Verilog simulation. This coupled system will be developed into large-scale networks of DSNs.
