NURODE: In-Memory Crossbar Core for Hodgkin-Huxley Model ODE-Based Computations

In this work, we present a memristor crossbar array-based hardware architecture designed to solve a system of differential equations for the Hodgkin-Huxley neuron model. The system extends from previous works to perform more computations in-memory, reducing the load of software processing and distributing them onto memristive hardware along with cheap shift-and-add operations. We demonstrate the properties of the solutions produced by the system follow the expected behaviours of the Hodgkin-Huxley model under various external currents.
