摘要
路由器芯片是互连网络的核心部件。介绍一种支持完全适应性维度气泡路由的新型路由器微体系结构。针对维度气泡完全适应性路由算法的特点,优化设计了路由器的输入缓冲以及仲裁开关逻辑。采用DC工具评估了新型路由器的面积以及延迟。实验结果表明,相对基于Duato方法的适应性路由器芯片,新型路由器芯片更容易获得更高的主频。
Router chip is a key component of interconnection network. A novel router microarchitec- ture is presented, which supports the fully adaptive Dimensional Bubble Routing Algorithm （DBRA）. According to the characteristics of DBRA, the design of input buffer, arbiter and switch of router is op- timized. The area and delay of router chip is evaluated by Design Compiler under the process of TSMC 40nm. The results show that the novel router chip is easier to achieve the higher frequency compared with the router chip based on Dauto＇s methodology.
