On-chip　multi-processor　technology　has　developed　rapidly　with　progress　in　manufacturing　processes,　resulting　in　a　continuous　increase　in　the　number　of　processor　cores　on　a　chip.　However,　increase　in　the　number　of　cores　leads　to　difficulties　in　communication　between　cores.　To　overcome　this　disadvantage,　a　network-on-chip　(NoC)　was　proposed,　which　replaced　traditional　bus　connections　between　cores　using　routers,　resulting　in　more　fluent　communication.　Although　the　quality　of　communication　services　has　improved,　the　NoC　still　faces　several　technical　challenges,　such　as　ensuring　the　execution　time,　controlling　the　network　delay　effectively　and　reducing　power　consumption　reasonably.　In　this　study,　we　introduce　a　new　topology　and　policy　in　router　of　NoC.　in　topology,　we　let　more　components　connected　with　on　router,　and　this　has　been　beneficial　in　reducing　power　consumption　because　of　the　reduction　in　the　number　of　routers.　In　policy,　we　adjusting　the　communication　scheduling　of　routers　and　dynamically　checking　changes　in　port　sequences　has　improved　the　communication　infrastructure　and　increased　the　network　throughput.　Besides,　dynamically　adjusting　the　position　where　the　minimum　unit　of　data　is　stored　in　the　router　significantly　reduces　the　congestion　of　the　network　and　relieves　the　pressure　of　link.　Compared　with　present　techniques,　through　the　power　consumption　is　reduced　by　about　15%-20%.　And　can　get　more　effect　when　compared　with　flattened　butterfly　this　effect　will　be　more　pronounced　with　the　increase　in　the　cores　and　tasks.
