Abstract: With the high demand of communication bandwidth for multi-processor system, combining LocalLink protocol and Batcher-Banyan switching network, this paper proposes a dynamic interconnection network which is fit to be realized in FPGA. Compared with traditional interconnection, communication performance is improved great, while only occupying a small quantity of hardware resource. The network is also convenient to integrate with new communication interface, brings forward a high performance and flexible interconnection method for multi-processor system design.
