Abstract
In this paper, both GPU (Graphing Processing Unit) based and FPGA (Field Programmable Gate Array) based hardware implementations for a discrete-time spiking neuron model are presented. This generalized model is highly adapted for large scale neural network implementations, since its dynamics are entirely represented by a spike train (binary code). This means that at microscopic scale the membrane potentials have a one-to-one correspondence with the spike train, in the asymptotic dynamics. This model also permit us to reproduce complex spiking dynamics such as those obtained with general Integrate-and-Fire (gIF) models. The FPGA design has been coded in Handel-C and VHDL and has been based on a fixed-point reconfigurable architecture, while the GPU spiking neuron kernel has been coded using C++ and CUDA. Numerical verifications are provided.

This generalized model is highly adapted for large scale neural network implementations, since its dynamics are entirely represented by a spike train (binary code). This means that at microscopic scale the membrane potentials have a one-to-one correspondence with the spike train, in the asymptotic dynamics. This model also permit us to reproduce complex spiking dynamics such as those obtained with general Integrate-and-Fire (gIF) models. The FPGA design has been coded in Handel-C and VHDL and has been based on a fixed-point reconfigurable architecture, while the GPU spiking neuron kernel has been coded using C++ and CUDA. Numerical verifications are provided.</div></front></TEI><affiliations><list><country><li>France</li><li>Mexique</li></country><region><li>Grand Est</li><li>Lorraine (région)</li><li>Provence-Alpes-Côte d'Azur</li></region><settlement><li>Nancy</li><li>Nice</li></settlement><orgName><li>Institut national polytechnique de Lorraine</li><li>Université Nancy 2</li><li>Université Nice Sophia Antipolis</li><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Provence-Alpes-Côte d'Azur"><name sortKey="Rostro Gonzalez, Horacio" sort="Rostro Gonzalez, Horacio" uniqKey="Rostro Gonzalez H" first="Horacio" last="Rostro-Gonzalez">Horacio Rostro-Gonzalez</name></region><name sortKey="Girau, Bernard" sort="Girau, Bernard" uniqKey="Girau B" first="Bernard" last="Girau">Bernard Girau</name><name sortKey="Torres Huitzil, Cesar" sort="Torres Huitzil, Cesar" uniqKey="Torres Huitzil C" first="Cesar" last="Torres-Huitzil">Cesar Torres-Huitzil</name></country><country name="Mexique"><noRegion><name sortKey="Barron Zambrano, Jose Hugo" sort="Barron Zambrano, Jose Hugo" uniqKey="Barron Zambrano J" first="Jose Hugo" last="Barron-Zambrano">Jose Hugo Barron-Zambrano</name></noRegion></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
