一种二维结构的互连路由设计与实现

Design and implementation for a two-dimensional structure of interconnect routing

针对阵列处理单元之间互连传输拥塞的问题,设计了一种在二维结构中互连的虚通道路由器模型。采用改进的自适应XY路由算法,智能地分配虚通道空闲资源,从逻辑上减少拥塞和等待时间,多路选择器交叉开关完成数据传输。通过ASIC设计,完成虚通道路由器硬件电路,应用Modesim工具进行仿真,达到网络互连传输的目的。

For the problem of array processing unit interconnection transmission, a virtual channel router is designed based on the Mesh of topological structure of interconnection transmission. It used an adaptive XY routing algorithm distributing virtual channel idle resources to reduce congestion and waiting time, and used multi-channel selector switch to complete data transmission. Through the ASIC design and Modesim tool for simulation, the virtual channel router hardware circuit was finished, and achieved the purpose of transmission network interconnection.
