Reduce Energy Consumption in Network on Chip with Providing an Efficient Mapping Algorithm

Network on Chip technology, NoC, is a perfect solution to control complex communication problem in system design. The first step in NoC-based designing for applications isselect NoC-topology such as mesh- topology. Operation mapping an application onto a mesh-based NoC is a NP-hard problem. So the mapping algorithms can be useful to reduce the algorithmic complexity as far as possible. In some mapping algorithms, priority selection for nodes is depend on select a neighbor node with high communication rate of pervious selected node. In these mapping algorithms, the edges with low communication rate are a problem. In this paper, the proposed mapping algorithm, tries to solve this problem with ignoring the low communication rate edges. To evaluate and compare the proposed algorithm, other mapping algorithms have been used such as Nmap, CastNet and Onyx. The proposed mapping algorithm has better result than other mapping algorithms for many applications such as VOPD and DVOPD.
