In this paper, we propose a novel interconnect-aware pipeline synthesis system for array based reconfigurable architectures. The proposed system includes interconnect-aware pipeline scheduling, post-placement communication scheduling and others. The experiments on a number of real-life examples demonstrate usefulness of the proposed method. For scheduling, our proposed interconnectaware pipeline scheduling has on average only 14% overhead compared to ILPbased exact solution in terms of latency, and can achieve the same initiation interval with much less computation time. For synthesis of array based netlist with a real FPGA device, our interconnect-aware pipeline synthesis system can speed up the clock period by up to 39%, compared to a conventional high leve synthesis system for array based reconfigurable architectures which utilizes loop pipelining technique but does not consider interconnect delays during scheduling phase. In addition, even when compared to a regular pipeline synthesis of general netlist, our proposed synthesis system can generate on average 18% clock period improvement. © International Federation for Information Processing 2007.
