摘    要:映射和路径分配是片上网络在编译过程中两个相辅相成的重要步骤,对系统的通信功耗影响很大。该文针对片上网络映射过程中现有路径分配法寻径不充分的问题,提出了一种基于列举的路径分配算法。该算法通过列举各通信流的所有合法路径,对路径的各种组合方式进行充分搜索。同时将路径分配算法应用到禁忌搜索映射算法中,并对映射算法做了改进,以适应路径分配算法。仿真结果表明,基于列举的路径分配算法提高了满足约束的路径被搜索到的概率,优化了映射算法的结果。

关 键 词:映射  片上网络  路径分配  禁忌搜索

Abstract:Two important steps,namely mapping and path allocation,are tightly bounded with each other in current network on chip(NoC) compiler technology,and have a large impact on the power consumed during communication.A novel algorithm is proposed for path allocation based on an enumerations scheme which enumerates legal paths of traffic,to search the routing paths combination in the NoC mapping process.The proposed algorithm is embedded to a tabu search mapping algorithm which is modified to adapt the behavior of path allocation.The simulation results show that the probability of finding the correct paths is increased within the bandwidth constraints and the mapping algorithm is optimized.
Keywords:mapping  network on chip  path allocation  tabu search
