This paper presents a new ring topology Network-on-Chip(NoC) architecture.By improving the input port virtual channel,the architecture completely prevents Head of Line blocking(HoL) and deadlock with one pipeline stage in a like Virtual output Queue(VoQ) way,without consuming too much resource.This paper evaluates the performance of this architecture under some different parameters.Compared with CELL EIB ring implementations,its packet minimum latency is only 11 cycles,while the maximum throughput is 25.6 Gb/s.
