We present an interconnection network, called Syncube, which is a new implementation scheme of hypercube. The hardware complexity of syncube is O(Nlog2N). Communication is much faster through syncube than that through a traditional hypercube with the same hardware complexity. We will give algorithm which can make full use of the connections and can realize log2N permutations simultaneously so that communication bandwidth is fully increased.
