APPARATUS FOR PROCESSING DATA AND METHOD THEREOF

摘要

According to an embodiment of the present invention, a data transmission device includes: a terminal communication part; a first control unit which extracts a command packet based on a command block rapper packet; and a first unit communication part transmitting the command packet to a second unit. When the first unit communication part receives a data status packet which is generated based on one or more data packets corresponding to the command packet from the second unit, the first control unit extracts the data packets from the data status packet in response to a packet relevant to a data transmission request from a host terminal. Then, the terminal communication unit transmits the data packets extracted from the data status packet to the host terminal.
