A cellular hardware implementation of a spiking neural network with run-time reconfigurable connectivity is presented. It is implemented on a compact custom FPGA board which provides a powerful reconfigurable hardware platform for hardware and software design. Complementing the system, a CPU synthesized on the FPGA takes care of interfacing the network with(More)
This paper introduces Perplexus, a European project that aims to develop a scalable hardware platform made of custom reconfigurable devices endowed with bio-inspired capabilities. This platform will enable the simulation of large-scale complex systems and the study of emergent complex behaviors in a virtually unbounded wireless network of computing modules.(More)
In this paper, we introduce the general architecture of a new electronic tissue called POEtic. This reconfigurable circuit is designed to ease the implementation of bio-inspired systems that bring cellular applications into play. It contains special features that allow a developer to realize systems that require evolution (Phylogenesis), development(More)
In this paper we present a new dynamic routing algorithm specially implemented for a new electronic tissue called POEtic. This re-configurable circuit is designed to ease the implementation of bio-inspired systems that bring cellular applications into play. Specifically designed for implementing cellular applications, such as neural networks, this circuit(More)
In this article, we try to analyze the requirements of developmental processes from the perspective of their implementation in digital hardware. After recalling the motivations for such an implementation, we concentrate separately on the two mechanisms (cellular division and cellular differentiation) that are exploited by biological systems to realize(More)
A novel multi-cellular electronic circuit capable of evolution and development is described here. The circuit is composed of identical cells whose shape and location in the system is arbitrary. Cells all contain the complete genetic description of the final system, as in living organisms. Through a mechanism of development, cells connect to each other using(More)
The implementation of bio-inspired systems in hardware has traditionally been more a matter of artistry than of method. The reasons are multiple, but one of the main problems has always been the lack of a universal platform, of a standardized architecture, and of a proper methodology for the implementation of such systems. The ideas presented in this(More)
In this article, we introduce the approach to the realization of ontogenetic development and fault tolerance that will be implemented in the POEtic tissue, a novel reconfigurable digital circuit dedicated to the realization of bio-inspired systems. The modelization in electronic hardware of the developmental process of multi-cellular biological organisms is(More)
