Original Abstract Submitted

An arithmetic processing device includes a first memory to hold a matrix, a second memory to hold data obtained by transforming elements in the matrix held in the first memory, a processor to transform the elements in the matrix and cause the second memory to hold the transformed elements by writing each of element-groups arranged in a row direction, which the element-groups are to be used for a matrix-product-operation with a filter in each row of the matrix, to each of a plurality of rows in the second memory in a sequence so that the elements in the element-groups arranged in a column direction of the matrix sequentially partially overlap with each other, and an accelerator to execute a convolution-calculation of the matrix by executing the matrix-product-operation of the filter and the element-groups written in the second memory, which the elements of the element-groups partially overlap with each other.
