英文摘要：

Three-dimensionalnetworkonchip （3D NoC） with its shorter global interconnections, higher packing density, smaller vol- ume, and many other advantages, has drawn more and more attention from both industry and academia. Mapping is a key problem on 3D NoC research and has a great impact on power consumption, latency and many other system performances. In this paper, some essential issues on 3D NoCmapping are introduced and many 3D NoC mapping algorithms are studied and classified into heuristic mapping algorithms and non-heuristic mapping algorithms, in which heuristic mapping algorithms include mapping algorithms based on genetic algorithm, particle swarm optimization algorithm, simulated annealing algorithm and ant colony algorithm. Existing mapping algorithms for 3D NoC are then summarized with the characteristics of each algorithm outlined. The possible hot research areas in fu- ture on3D NoCmapping algorithms arealso discussed in the last part.
