The invention discloses a vector processor-oriented vectorization realization method for two-dimensional matrix convolution. The method comprises the steps of S1, moving a convolution matrix A and a convolution matrix B to a vector storage unit and a scalar storage unit respectively through a DMA controller; S2, multiplying a row of elements of the convolution matrix A by a row of corresponding elements after broadcast of an element of the convolution matrix B in a one-to-one correspondence manner, and accumulating results; S3, extracting first K-1 elements of the row of the elements extracted from the convolution matrix A to a vector processing unit through a shuffle instruction, multiplying the first K-1 elements by the second element, extracted currently and broadcast to the vector processing unit, of the convolution kernel matrix B in a one-to-one correspondence manner, and accumulating results; S4, judging whether the calculation of the row of the elements is finished or not; and S5, enabling data addresses of the two matrixes to point to a next data row, finishing the calculation of a first row of elements of a matrix C, and finishing the calculation of the whole matrix C through circulation. The method has the advantages that the principle is simple, the operation is convenient, the algorithm parallelism can be greatly improved, the calculation efficiency is improved, and the like.
