Abstract:
1. A communication control device comprising: a plurality of reception controllers capable of receiving data in a burst transfer mode in which a plurality of packets are continuously transferred as one burst; a plurality of dedicated buffers having a capacity of at least one packet and corresponding to said reception controllers, respectively; and a plurality of common buffers having a capacity of at least the number of packets continuously transferred in said burst transfer mode and shared by a plurality of said reception controllers; wherein when said burst transfer mode is started, a first packet of a burst is buffered in at least one of said dedicated buffers and subsequent packets of said burst are buffered in at least one of said common buffers, wherein said first packet of said burst is buffered in said at least one of said dedicated buffer and said subsequent packets of said burst are buffered in a region of said at least one of said common buffers, wherein when a burst transfer has been completed, said region of said at least one of said common buffers has an empty region having a size of at least one packet in said at least one of said common buffers, wherein said at least one of said common buffers is adapted for buffering a first packet of a subsequent burst transfer in said empty region and continuing to buffer subsequent packets by securing another region of said at least one of said common buffers in said burst transfer mode, and wherein said region of said at least one of said common buffers has a size corresponding to a packet size×a maximum burst length.
