DRAFT: Flexible interconnection network for dynamically reconfigurable architectures
Ludovic Devaux, Sana Ben Sassi, Sébastien Pillement, Daniel Chillet, Didier Demigny · 2009
Dynamic and partial reconfiguration allows to place on line the various tasks that describe an application, in available regions of an FPGA. This new feature leads notably to communication problems since tasks are not present in the matrix during all computation time. In this article, we compare popular interconnection architectures. From this study, the DRAFT network is designed to support the communication constraints required by the dynamic reconfiguration. DRAGOON, the automatic generator of networks providing the DRAFT topology, is presented with DRAFT first implementation results and network performances.
