摘要
为实现低能耗片上网络(NoC)规则Mesh的映射,提出一种基于NoC规则Mesh的映射算法。根据规则拓扑结构的对称性,得出第1个核多个等价映射最优解,并保留其中一个解,从而缩小搜索空间,并结合分枝界限算法的剪枝原理,对其余核依次进行映射。实验结果表明,该算法具有较低的通信代价和较短的运行时间。
This paper presents an efficient algorithm to solve a mapping problem of the Network on Chip（NoC） regular architecture under low power constraints.According to symmetry of the regular topological structure,the algorithm only keeps one equivalent optimal solution for the first core mapping result.Then combining with the pruning principle of branch and bound algorithm,the algorithm mappings the rest cores.Thus the algorithm reduces the search space,speeds up the convergence rate and reduces the operating time.Experimental results show that the algorithm has lower communication cost and short run time.
