提出了一种保证片上网络带宽或延迟的方法。该方法包含三个核心：流量分类，基于微片的切换，路径预分配和链路带宽设置。与传统的电路交换方法相比，该方法可以保证源节点产生一个微片到目的节点接收微片的时延。该方法还支持广泛的流量类型，例如延迟关键、低BW流量和仅具有BW要求的流数据。此外，路由器和网络接口，支持所提出的方法实现和最大延迟公式的开发。仿真和综合结果表明，该方法能较好地保证带宽和时延，且成本相对较低。
A method is proposed to guarantee bandwidth (BW) or latency of network-on-chip. This method contains three kernels: traffic classification; flit-based switching; path pre-assignment and link-BW setting. Compared with the traditional circuit-switch method, the proposed method can guarantee the latency between one flit's generation in the source node and its reception in the destination node. This method also supports a wide range of traffic types such as latency critical, low BW traffic and streaming data which only have BW requirement. Moreover, router and network interface which support the proposed method are implemented and a maximum latency formula is developed. Simulation and synthesis results show that this method can guarantee the BW and latency well and is relatively low cost.
