Abstract
Interconnect reduction is one of the key issues in high-level synthesis. In this paper, we propose a primal-dual based method to solve the functional unit (FU) and register binding simultaneously while minimizing the global interconnection. Specifically, the binding problem is formulated as a min-cost network flow based on splitting weighted and order compatibility graphs (SWOCGs). The interconnect sharing among registers and FUs are maximized by binding the the operations or variables on the same path to the same FUs or registers according to the flow. Experimental results show that, compared with the previous greedy method [7], our proposed algorithm achieves an average 4.8% further reduction in global interconnection for a suite of benchmarks.
