Résumé: Within the EU-funded Perplexus project, a specific multiprocessor architecture has been developed to model complex networks of bioinspired spiking neuron models. The architecture is based on a Single-Instruction Multiple-Data (SIMD) scheme including ad-hoc instructions and features and a special-purpose Adress-Event Representation (AER) bus for efficient spike broadcasting. After introducing the Perplexus project frame and the so-called ubichip that includes the SIMD multiprocessor architecture, the most interesting features of this architecture are detailed, as well as the development tools for debugging and prototyping currently available, in particular the SpiNDeK design tool and the ubidule prototyping platform.
Note biographique: Jordi Madrenas received the M.Sc. and Ph.D. degrees in Telecommunication Engineering from the Technical University of Catalunya (UPC), Barcelona, Spain, in 1986 and 1991, respectively. He is currently Associate Professor at the Department of Electronic Engineering, UPC. Between 2000 and 2003 he was Vice-Dean of Studies of the Telecommunication Engineering School of Barcelona, UPC. He has participated in several European and Spanish national research projects. Currently he coordinates a national research project on microsensor conditioning and bioinspired signal processing and he has co-authored more than 90 scientific papers in journals and conference proceedings and 5 book chapters. His research interests include analog, mixed-signal and digital VLSI and FPGA design, e-beam testing, bioinspired neural and neuromorphic systems implementation, focal-plane image segmentation, field-programmable mixed-signal arrays and MEMS conditioning.
