Placement and Floorplanning in Dynamically Reconfigurable FPGAs
9 months ago
This paper proposes a novel approach for resource- and reconfiguration- aware floorplanning. Different from existing approaches, our floorplanning algorithm takes specific physical constraints such as resource distribution and the granularity of reconfiguration possible for a given FPGA device into account. These physical constraints are typically considered at the later placement stage. In order to emphasize this fundamental difference with respect to traditional floorplanners, we refer to our approach as a floorplacer. Different aspects of the problems have been described, focusing particularly on the FPGA’s resource heterogeneity and the temporal dimension typical of reconfigurable systems. Once the problem is introduced a comparison among related works has been provided and their limits have been pointed out. Our proposed approach specifically considers the feasibility of the associated communication infrastructure for a given floorplan. Experimental results proved the validity of the proposed approach.
