In this article, we show how the use of a bio-inspired dynamic task replication algorithm, in the context of stream processing, can be used to significantly improve the performance of embedded programs. We also show that this programming methodology, which is not tied to a particular implementation, can also be used as an heuristic for task mapping in the context of embedded multiprocessors systems...
Because of the increasing developments of humanoid robots, humans and robots are going to interact more and more often in the near future. Thus, the need for a well-defined ethical framework in which these interactions will take place is very acute. In this article, we will show why responsibility ascription is a key concept to understand today's and tomorrow's ethical issues related to human-robot...
In this article, we describe a novel hardware platform aimed at the realization of cellular architectures. The system is built hierarchically from a very simple computing unit, called ECell. Several of these units can then be connected, using a high-speed serial communication protocol, to a more complex structure called the UltraStack. Consisting of four different kinds of interconnected boards (computational,...
Cellular architectures represent the natural approach to apply bio-inspired mechanisms to the world of digital hardware. To derive any useful property (in terms of computation) from these mechanisms, however, it is necessary to examine systems that are large enough to pose problems for conventional design methodologies. Moreover, implementing these mechanisms in actual hardware is the only way to...
The application of evolutionary techniques to the design of custom processing elements bears a strong relation to the natural process that led to the co-evolution of cells and genomes in biological organisms. As such, it is an interesting avenue for an effective application of evolutionary approaches in the domain of hardware design. The architecture of conventional non-configurable processors, however,...
In this article, we propose a novel partitioning method for hardware-software codesign based on a genetic algorithm that has been enhanced for this specific task. Given a high-level program and an area constraint, our software considers different granularities levels to discover the most interesting blocks to be implemented in ad hoc functional units that can then be used as new instructions in a...
