Abstract

Placement and scheduling are recognized as the most important problems when exploiting the benefit of partially reconfigurable devices such as FPGAs. For example, dynamically loading and unloading modules onto an FPGA causes fragmentation, and—in turn—may decrease performance. To counteract this effect, we use methods from algorithmics and mathematical optimization to increase the performance and present algorithms for placing, scheduling, and defragmenting modules on FPGAs. Taking communication between modules into account, we further present strategies to minimize communication overhead. Finally, we consider scheduling module requests with time-varying resource demands.
