The present invention discloses a vectorization realization method of fusing an ReLU activation function and the max pooling. The method comprises the steps of S1 calculating the ReLU activation function value of a matrix A; S2 calculating the max pooling of the matrix after the ReLU activation function processing in the step S1; S3 repeating the steps S1 and S2 until all sub-blocks of the matrix A are traversed, and finally finishing the ReLU activation function processing and the max pooling operation of the whole matrix A. The method of the present invention has the advantages of being simple in principle, being convenient to realize, being able to fully excavate the parallel calculation capability of a vector processor and the parallelism of an algorithm, etc.
