摘要 为了解决非对称Omega+Omega混洗网络的拓扑等价问题,提出一种新的方法。对Omega+Omega网络的左或右半部分节点对应的二进制位进行逆操作,将取逆操作后得到的混洗网络与另一半混洗网络串联,中央级间的连接根据具体的规则采用简单蝶互连或复杂蝶互连方式,从而将非对称的Omega+Omega混洗网络转变为对称的Omega-1+Omega或Omega+Omega-1混洗网络,最后得到它们之间拓扑等价。 In order to obtain the topological equivalence of the asymmetric Omega-Omega network,a novel method is presented. The method states that an N×N 21og2^N-stage asymmetric Omega＋Omega network can be converted into a symmetric N×N 21og2^N-stage Omega^-1＋ Omega network or Omega ＋ Omega ^-1 network through the bit-reversed order rearrangement of the node＇s binary address, simultaneously, the center-stage connection is composed of simple butterfly and/or complex butterfly connections. At last,the topological equivalence between Omega-Omega network and Omega^-1 ＋Omega network or Omega＋Omega ^-1 is verified.
