Abstract
A graphics processor includes a texel unit and an execution unit. The texel unit includes a loading module. The execution unit includes an im2col module to execute an im2col algorithm to expand an original matrix to obtain an expansion matrix according to the size of a kernel. The execution unit multiplies the expansion matrix and the kernel to obtain a feature map matrix. The loading module calculates feature coordinates of each element of the feature map matrix according to the coordinates of the expansion matrix, and obtains the original coordinates of each element of the original matrix according to the feature coordinates, the size of the kernel, a stride, and padding. The loading module reads at least one of the memory blocks covered by the original coordinates of each element of the original matrix, and outputs data corresponding to the original coordinates in the memory blocks.
