摘要： 文章提出了一种针对片上网络的组播通信模型，能够为片上网络提供无死锁的通信。该模型能显著减少总通信量，增加通道利用率；在测试模式下，能有效节省测试时间。将该模型仿真应用到二维带环网格拓扑结构的片上网络中，试验结果表明，该模型较单播通信具有更小的平均传输延迟和更高的吞吐量。

Abstract: A model of multicast communications is proposed for NoC (networks on chip) to provide communications to guarantee deadlock-free routing. Multicast model has the capability of reducing traffic remarkably, increasing utilization ratio of channels and decreasing testing time in test mode. Modeling of the multicast communications were simulated and applied on 2D Torus NoC. Experimental results demonstrate that our communications model has lower average communication latency and higher throughput than unicast communications.
