Abstract: This paper mainly discusses the design and implementation of convolution computation in image processing on MCC-SIMD computer. By a detailed study on the current literature, in terms of graph, this paper proposes formal definitions on convolution calculation by the method of convolution path. It analyzes the regular pattern of the shift of PE array while calculating on data parallel convolution on 4-connected convolution path. On the basis of the above, a data parallel algorithm of convolution calculation is proposed. In the end, computation complexity and communication complexity are analyzed. Also ,some conclusions concerned have been proved.
