Abstract:
A packet transfer control apparatus for transferring a packet in the form of one of consecutive packets including blocks of data and a non-consecutive packet, comprising:a first buffer circuit for storing blocks of data included in the consecutive transfer packets; a memory unit connected to the first buffer circuit, for storing the blocks of data provided from the first buffer circuit; a direct memory access control unit connected to the first buffer circuit and the memory unit, for controlling a direct transfer of the blocks of data between the first buffer circuit and the memory unit; a packet identification unit connected to the first buffer circuit for receiving the packet and determining whether the packet is one of the consecutive packets and the non-consecutive packet and providing the consecutive packets to the first buffer circuit; and a transmitting unit for generating and transmitting a response packet corresponding to the non-consecutive packet, wherein the transmitting unit generates and transmits the response packet while the first buffer circuit and the memory unit perform the direct transfer operation.
