摘要: 该文提出了一种基于螺旋线的 Round-Robin(R-R)crossbar调度算法,在调度级和迭代级分别轮询R-R指针,避免了指针同步;在输入端口轮询和迭代匹配的二维过程,执行流水线操作。当端口数32时,执行效率高,带宽利用率高,逻辑简单,容易实现。通过对R-R加权,可以保证Non-uniformtraffic高吞吐量。Abstract: In this paper, the Round-Robin crossbar scheduling algorithm based on spirality is proposed. It addresses the R-R pointers in scheduling and iteration, respectively, to avoid the synchronic of pointers. And it pipelines the polling of input ports and the steps of iteration in 2 dimensional. When the number of ports is less than 32, it has simple logic and performs better. In addition, by weighting the R-R, it can provide high throughput for non-uniform traffic.
