Abstract

The disclosure relates to an image filtering processing system, which includes a temporary memory; a flow controller configured to control a feature and a weight to be stored at a point of the temporary memory, and, when at least one of the feature and the weight has a value of 0, to control next feature and next weight to be overwritten at the point; and a processing element configured to performa multiplication operation on a value of the feature and a value of the weight in the temporary memory and an addition operation on the multiplication result.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0173358 filed on December 31, 2018, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The exemplary embodiments relate to a processing system. Background technique [0004] Convolutional Neural Networks (CNNs) are processing systems primarily used for image recognition and analysis. This processing system requires a convolution operation that extracts features from an image using a specific filter by performing multiplication and addition operations using a matrix multiplication unit. This unit of operation can be used efficiently when using dense images and filtering, i.e. when the data has a small number of zeros (i.e., the data has less sparsity), but the sparseness of most images and filtering used in processing systems The degree is from about 30% to about 70%. [0005] As the sparsity...
