A Winograd algorithm multiplies a first matrix by a second matrix to generate a third matrix. A plurality of second accumulated value calculation units, accumulates second multiplication values obtained by multiplying each of paired element values of the second matrix, a second accumulated value output unit outputting selecting and outputting one of output values of adjacent second accumulated value calculation unit and an accumulated second multiplication value as a second accumulated value, a third accumulated value output unit including a plurality of third accumulated value calculation units and generating third accumulated value, and one or more row element value calculation units, of which one row element value calculation unit accumulates first matrix element multiplication values obtained by multiplying each of the paired element values of the first matrix, and calculates element values of the third matrix using the accumulated first matrix element multiplication value and the second accumulated value.
