This paper presents a novel clustered Network-on-Chip(NoC) architecture for multi-core processor.The proposed architecture is a cluster array organized as a two-dimensional mesh.Each cluster includes three processors,one Direct Memory Access(DMA) and one cluster shared memory.The multi-core processor using such NoC architecture can obtain high communication efficiency and memory utilization ratio.It design a four-cluster prototype system and implement the 3 780-point Fast Fourier Transform(FFT) on it.In FFT...
