ABSTRACT:
A data transfer device includes: a plurality of storage devices (10) including a plurality of transfer sources (TS) of which storage regions are different from each other and setting registers (40) of which number is equal to the number of the transfer sources (TS). The setting registers (40) stores for the transfer sources (TS) DMA transfer settings of the transfer sources (TS), and a DMA control section (20) performs data transfer control on the basis of the set values of the setting registers (40).
