The estimated bound takes into account the effects of resource sharing. It is shown that by introducing Lagrangian multipliers and relaxing the low power bind-ing problem to the Assignment Problem, which can be solved in O(n3), a tight and fast computable bound is achievable. Experimental results show the good quality of the bound. In most cases, deviations smaller than 5% from the optimal binding were observed. The proposed technique can for example be applied in branch and bound high-level synthesis algorithms for efficient pruning of the design space. The estimated lower bound can also be used as a starting point for low power binding heuristics to find optimal or near optimal binding solutions.} @COMMENTBibtex file generated on
