摘 要: 提出一种基于树的片上网络(network on chip,NoC)组播路由算法。根据目标应用中组播通信特征的不同,算法通过缩放因子的控制可以生成不同形状的组播树,从而得到性能、带宽效率各不相同的组播路由。结果表明:采用较小的缩放因子时,所提出的组播算法在性能上与虚电路树(virtual circuit tree multicasting,VCTM)的组播算法接近;采用较大的缩放因子时,所提出的组播算法在性能上与最优树(opitimized tree,OPT)的组播算法接近。
关 键 词: 计算机系统结构;片上网络;基于树的组播;可配置

Abstract: In this paper, a configurable tree-based network on chip (NoC) multicast routing algorithm was proposed to generate different shaped multicast trees. According to the characteristics of communication in application, varies scaling factors could get different shaped multicast paths, lead to differences in performance and band width efficiency. The experiment results showed that the proposed algorithm with small scaling factor gave similar performance to virtual circuit tree multicasting (VCTM), while the proposed algorithm with large scaling factor performance was similar to opitimized tree (OPT).
