The invention discloses a convolution operation device for a convolutional neural network. The convolution operation device comprises an enabling matrix acquisition module, an enabling matrix controller, a to-be-convolved matrix controller, a convolution kernel matrix controller and a convolution operation module. The enabling matrix acquisition module sets the non-zero element values of the to-be-convolved matrix X and the convolution kernel matrix W as the first preset values so as to acquire a to-be-convolved enabling matrix X' and a convolution kernel enabling matrix W '; and sequentially sending the elements of the to-be-convolved matrix X and the convolution kernel matrix W to the convolution operation module via the enabling matrix controller, the to-be-convolved matrix controller and the convolution kernel matrix controller . The convolution operation module performs multiplication operation on the corresponding elements in the to-be-convolved matrix X and the convolution kernel matrix W only when the
