DMA TRANSFER CONTROL DEVICE AND METHOD OF DMA TRANSFER

摘要

A DMA transfer control device for controlling a DMA transfer between a source and a destination is provided. The DMA transfer control device has: a buffer in which a transfer data is stored; and a bus cycle generation unit performing a burst transfer of the transfer data between the buffer and the source or the destination. The bus cycle generation unit performs an undefined-length burst transfer until an access address reaches a burst address boundary in the source or the destination. The bus cycle generation unit performs a fixed-length burst transfer after the undefined-length burst transfer until transfer of the transfer data is completed.
