Abstract
"Synaptic Rewiring in Neuromorphic VLSI for Topographic Map Formation", Robotics, Brain and Cognitive Sciences Dept., Italian Institute of Technology. 9th Apr 2008.
The term neuromorphic was coined by Carver Mead, in the late 1980s to describe Very Large Scale Integration (VLSI) systems containing electronic analog circuits that mimic neuro-biological architectures present in the nervous system.
I will talk about topographic, largely neuronal maps in biology, how I've modelled their development, and how I've implemented this model in neurmorphic VLSI. I will focus on Address-Event Representation (AER), a protocol for transmitting neural pulses, and will present a design for an AER receiver which is optimised for scalability as connection fan-out increases. I'll further discuss the rewiring of connections and will present a circuit for calculating Euclidean distance across a chip.
