Boundary convolution calculation method and device, hardware accelerator and computer equipment

The invention discloses a boundary convolution calculation method and device, a hardware accelerator and computer equipment. The method comprises the steps of: loading a current image; if the currentimage is a first part of a whole image, executing first local convolution calculation for a first boundary element of the current image, and storing a result in an internal storage module; and if not,executing second local convolution calculation for a second boundary element of the current image, and taking out a first local convolution calculation result of a target adjacent image from the internal storage module, and adding and combining a second local convolution calculation result of the current image and the first local convolution calculation result of the target adjacent image to obtain a convolution calculation result of the boundary elements between the current image and the target adjacent image. According to the method, local convolution calculation and temporary storage are carried out on the boundary
