摘要： According to an aspect of an embodiment, a data transfer device comprises a plurality of transfer circuits managed by a processor, a request accepting unit, a status information collecting unit and a notification data generating unit. The plurality of transfer circuits each controls transfer of data. The request accepting unit accepts a transfer request from at least one of the plurality of transfer circuits. The status information collecting unit collects status information indicating status of data transfer relating to all of the plurality of transfer circuits, upon acceptance of the transfer request. The notification data generating unit generates notification data including information of the transfer circuit regarding which the request accepting unit has received the transfer request and status information collected by the status information collecting unit. And the notification data generating unit transmits the generated notification data to the processor.

摘要： A pointer comparing unit determines whether a value of a writing pointer is identical to a value of a reading pointer. When it is determined that the value of the writing pointer is different from the value of the reading pointer, an inter-memory transfer unit reads data stored in a location where a data transfer apparatus reads transmission data from a transmission ring buffer, transfers the data to a reception memory, and writes the data in a location designated by the reading pointer of a reception ring buffer. When the inter-memory transfer unit completes writing of the data in the reception ring buffer, a reading-pointer updating unit updates the reading pointer.
