The method comprises: compressing a plurality of weight values in a weight matrix and indices of an input vector into a compressed main stream; storing M sets of synapse values in M memory devices; and, performing reading and MAC operations according to the M sets of synapse values and the compressed main stream to obtain a number M of output vectors. The step of compressing comprises: dividing the weight matrix into a plurality of N×L blocks; converting entries of a target block and corresponding indices of the input vector into a working block and an index matrix; removing zero entries in the working block; shifting non-zero entries row-by-row to one of their left and right sides in the working block; and, respectively shifting corresponding entries in the index matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for matrix by vector multiplication for use in artificial neural network","description":"A method for matrix by vector multiplication, applied in an artificial neural network system, is disclosed.
