Abstract: Provided is a method of optimizing calculation of a convolutional layer including a plurality of channels and a convolutional neural network (CNN) accelerator. The method includes a classification operation of classifying weights of the plurality of channels as outlier (OL) elements and non-outlier (NOL) elements, a combination operation of combining two or more NOL elements which are put into calculation with the same activation value and present at the same slot in the plurality of channels, and a scheduling operation of moving a scheduling candidate element in a fetch window after the combination operation to a slot which is assigned no value.
