| Abstract(in English) | This paper shows a method to reduce the number of cell outputs for an LUT cascade with intermediate outputs by considering encoding. Reduction of the number of rail outputs reduces the number of outputs of LUTs and, the number of levels. Reduction of the number of outputs of LUTs reduces the amount of memory, while the reduction of the number of levels reduces the evaluation time. We use a BDD for characteristic function (BDD_for_CF) in the design. Experimental results show that our approach reduces the number of outputs of LUTs by 10%, and sometimes reduces the number of levels as well. |
