WebSimilarly to the ordinary butterfly, Benes network is hierarchically recursive. BN n contains two copies of BN n-1 as subgraphs, denoted as upper BN n-1 0 and lower BN n-1 1. A key property of the Benes network is that it is rearrangeable complete network: for any permutation of inputs to outputs there is a contention-free routing. Let us state ... china construction oceania north east linkWebThe Butterfly Permutation The butterfly permutation, β(x), is defined formally as. β(a n, a n-1, .. a 2, a 1) = {a 1, a n-1, .. a 2, a n}.
