MULTIPLE PRECISION INTEGER MULTIPLIER BY MATRIX-MATRIX MULTIPLICATIONS USING 16-BIT FLOATING POINT MULTIPLIER

摘要

A computer-implemented method, computer program product, and apparatus are provided. The method includes substituting NxN first integer elements, among a plurality of first integer elements obtained by dividing first integer data expressing a first integer in a first digit direction, into a first matrix having N rows and N columns. The method further includes substituting each of one or more second integer elements, among a plurality of second integer elements obtained by dividing second integer data expressing a second integer in a second digit direction, into at least one matrix element of a second matrix having N rows and N columns. The method also includes calculating a third matrix that is a product of the first matrix and the second matrix. The method includes outputting each matrix element of the third matrix as a partial product in a calculation of a product of the first integer and the second integer.
