Abstract
A data transfer device which controls data transfer between a first memory device and a second memory device, includes a first transfer arbiter circuit and a second transfer arbiter circuit. The first transfer arbiter circuit outputs, in response to a transfer instruction for transfer of data from the first memory device to the second memory device, first transfer instructions to transfer data in a first transfer unit in an order of addresses. The second transfer arbiter circuit outputs, in response to the first transfer instruction, second transfer instructions to transfer the data of the first transfer unit in a second transfer unit smaller than the first transfer unit. The second transfer arbiter circuit outputs the second transfer instruction in an order of accessible addresses in the first and second memory devices.
