| 摘 要： | 采用虫孔交换和虚拟通道技术的片上网络系统(NoC)能极大地降低传输延时,防止微片拥塞,增大网络吞吐率,从体系结构上解决了总线通信技术的瓶颈。片上网络的虚拟通道由多个缓冲区组成,其数目直接影响芯片的面积,必须通过仿真得到面积和缓冲区数目的平衡。使用NIRGAM仿真器对不同缓冲区数目的 2D Mesh片上网络进行了仿真,对其源代码中几个重要参数提出了修改建议,仿真结果表明,在本文配置的通信情况下缓冲区深度为4微片时NoC系统整体性能最好。

| Abstract: | The Network-on-Chip （ NoC ） system based on wormhole switching mechanism and virtual channel techniques can decrease the transmission latency, avoid the flow congestion and increase the throughput of the network. It has solved the bottleneck of BUS communication from architecturally. The number of buffers of the virtual channel determines the die area. It is necessary to simulate and strike a balance between them. NIRGAM is adopted to simulate the 2D Mesh network under different number of buffers. Modification for several parameters in the source code is proposed. Simulation results show that with the configuration of communication in this paper, NoC has the best performance when the depth of buffers is 4 flits. |
