A neuromorphic IC connection between cortical dendritic processing and HMM classification

We show connections between dendritic processing structures and hidden-Markov model (HMM) decoding that we arrived at through simultaneous circuit design of these systems. From an integrated circuit (IC) towards a biology perspective, these simple spreading networks relate well to cable theory and are similar to biological structures such as dendrites and cortical cells. Going in the other direction, from IC to classical digital signal processing (DSP), these structure hold similarities to HMM decoders. In order to implement both structures requires a compact array of variable conductance elements. Using floating-gate transistors, we are able to individually vary the conductance of each diffuser element in the array, which dramatically changes the analysis of these arrays.
