Outline of Final Research Achievements

In this study, a novel hardware-efficient asynchronous bifurcation processor, which can mimic nonlinear responses of neurons and their underlying occurence mechanisms, was designed. Also, a novel hardware-efficient asynchronous bifurcation processor, which can mimic nonlinear responses of spines, was designed. Furthermore, a novel hardware-efficient asynchronous bifurcation processor, which can mimic nonlinear responses of cochlea's basilar membranes and their underlying occurence mechanisms, was designed.
