Wave digital emulation of spike-timing dependent plasticity

Neuromorphic circuits are potential candidates for solving costly computations in an efficient manner. Such circuits, mimicking partial functionalities of the brain, need a large number of components. Simulation models are appropriate for first investigations, but they are very time-consuming regarding complex systems. Hardware realizations of specific components, like memristive devices, in such circuits are not possible for a desired functionality. We propose a methodology based on emulation techniques to overcome such problems. Therefore, the wave digital method has been utilized to get a digital replica of a memristive circuit mimicking long-term changes in the strength of synaptic coupling. In this work, both long-term potentiation as well as long-term depression are successfully emulated. This approach can also be used for a partial emulation of the subsystems, e.g. only memristive devices, of a more complex overall system.
