The invention provides a data transfer device for multidimensional memory capable of performing an efficient SIMD operation and suitable for transferring data between a multidimensional memory and a one-dimensional memory. A DMAC reads data of a rectangular area in a logical two-dimensional space of a two-dimensional data access memory, and writes the read data on a one-dimensional data access memory. Further, it reads data from the one-dimensional data access memory, and writes the read data on the two-dimensional data access memory, such that the data are arranged in the rectangular area in the logical two-dimensional space of the two-dimensional data access memory.
