Love Singhal, a Ph.D. candidate in computer science, and professor of computer science Eli Bozorgzadeh received the Best Paper Award at the 2006 IEEE International Conference on Field Programmable Logic and Applications (FPL’06) that took place in Madrid, Spain, August 28-30 2006. The awarded paper is titled “Multi-layer Floorplanning on a Sequence of Reconfigurable Designs.”
The dynamic partial reconfigurability of programmable devices such as FPGAs is characterized by their ability to reconfigure subsets of their logic and routing resources at runtime. This intrinsic dynamic reconfiguration results in accommodation of complex and dense designs, on-fly adaptivity, and design modification. Reconfigurable module can be a new coprocessor implemented on a FPGA device, an upgraded implementation of the existing module, or a reconfigured memory block. However, partial reconfiguration comes with the cost of reconfiguration overhead delays. In order to reduce the reconfiguration overhead, two consecutive similar sub-designs should be placed in the same locations to get the maximum reuse of common components.
In this paper, a new multi-layer sequencepair- based floorplanner is proposed for a given sequence of reconfigurable designs. In the experiments, compared to a traditional sequential floorplanner, the new floorplanner removes infeasibility in many designs, and provides faster timing closure.
FPL is the first and largest conference on programmable logic which encompasses a wide range of research area on FPGAs, including applications, novel system architectures and CAD tools, embedded processors, dynamic recon figuration, etc. The acceptance rate in FPL 2006 was 28 percent, out of 307 submissions.
