A x network, which is a concatenation of 2 Ω networks [2], along with a simple control algorithm is proposed. This network is capable of performing all Ω network realizable permutations and the bit-permute-complement (BPC) class of permutations [5] in O(log N) time. The control algorithm is actually a multiple-pass control algorithm on the Ω network, which is more general than Pease's LU decomposition method [6] and Lenfant's decomposition method [4].
