A VLSI architecture for modeling intersegmental coordination

Abstract

A hybrid analog/digital VLSI architecture that models the coordination of neurobiological segmental oscillators is presented. This architecture facilitates the modeling of systems such as those that produce swimming in vertebrates and fish, as well as motivates the creation of a class of biologically inspired, "intelligent" motion-control systems. The two primary components of the architecture are described: intrasegmental oscillators that consist of neurons and synapses that are implemented primarily rising analog VLSI circuits; and an intersegmental communication network that is implemented, primarily rising asynchronous digital circuits. Preliminary test results are presented to demonstrate the operation of the system and its components.
