Abstract
A data transfer apparatus includes a memory having first and second queues for storing data transfer information that includes information specifying a first memory area and information specifying a second memory area, a first processor which registers the data transfer information in the first or second queue, and a second processor performing a processing to transfer data stored in the first memory area to the second memory area. The second processor reads out the data transfer information registered in the first queue, transfers the data based on the read data transfer information, and decides if data transfer information succeeding to the read data transfer information is registered in the first queue. If the succeeding data transfer information is registered, the second processor reads out the succeeding data transfer information from the first queue, and performs the data transfer processing based on the read data transfer information.
