Dynamic Routing on the Ubichip: Toward Synaptogenetic Neural Networks

Abstract

The ubichip is a bio-inspired reconfigurable circuit developed in the framework of the european project Perplexus. The ubichip offers special reconfigurability capabilities, being the dynamic routing one of them. This paper describes how to exploit the dynamic routing capabilities of the ubichip in order to implement synaptogenetic neural networks. We present two techniques for dynamically generating the network topology, we describe their implementation in the ubichip, and we analyse the resulting topology. This work constitutes a first step toward neural circuits exhibiting more realistic neural plasticity features.

Synchronous Digital Implementation of the AER Communication Scheme for Emulating Large-Scale Spiking Neural Networks Models

“…The major outcome of this project is an integrated circuit, called Ubichip [2]. The internal architecture of the Ubichip has been endowed with specific hardware mechanisms, like dynamic routing [3] or self-replication [4] so as to provide support for a wide range of bio-inspired principles. Additionally, it supports massively parallel SIMD (Single Instruction Multiple Data) like data flows, thus making it a perfect candidate for the efficient emulation of Spiking Neural Networks (SNN) models [5].…”
