Abstract

This paper describes an interconnection scheme and its associated mapping method, used to program complex functions onto reconfigurable architectures, based on nanoscale logic cells. To interconnect such fine-grain logic cells, classical techniques are not suitable because of a large overhead. Therefore, we propose the use of static and incomplete interconnection topologies. We also propose a method to map functions onto such architectures. To evaluate the 4 different proposed topologies, we test mapping efficiency, performances and fault tolerance. The analyses show that this approach could improve the scalability of traditional EPGAs by a factor of 8.
