ABSTRACT:
An objective of the present invention is to provide a data transfer control device and electronic equipment which make it possible to reduce processing overheads in the firmware and implement high-speed data transfer. In a data transfer control device in accordance with the IEEE 1394 standard, the header of a packet is written to a header area, the ORB (data for SBP-2) of the packet is written to an ORB area, and the stream (data for the application layer) of the packet is written to a stream area. The stream area is managed by hardware in accordance with full and empty signals. Indication information is comprised within a transaction label tl of a request packet, and the header, ORB, and stream of a response packet are written to areas indicated by the indication information comprised within tl, when the response packet is received. The device is also provided with registers TSR and TER that contain addresses TS and TE for securing a transmission area in the stream area and registers RSR and RER that contain addresses RS and RE for securing a reception area therein.
