N2 - This paper represents a modified datapath merging technique to amortize the configuration latency of mapping datapaths on reconfigurable fabric in Run-Time Reconfigurable Systems (RTR). This method embeds together the different Data Flow Graphs (DFGs), corresponding to the loop kernels to create a single datapath (merged datapath) instead of multiple datapaths. The DFGs are merged in steps where each step corresponds to combining a DFG onto the merged datapath. Afterwards, the method combines the resources inside the merged datapath to minimize the configuration time by employing the maximum weighted clique technique. The proposed merging technique is evaluated using the Media-bench suit workloads. The results indicate that our technique outperforms previous HLS approaches aimed at RTR systems and reduces the datapath configuration time up to 10%.
