Backbone channel management method and backbone channel management apparatus

A backbone channel management apparatus that transmits first through third channel packets among Advanced eXtensible Interface (AXI) 5 channel packets through a backbone channel, comprising:

• a transmitting interface unit comprising:
• an input buffer having first through third input packet buffers that store the first through third channel packets, respectively;
• and
• a transmitting channel management unit configured to divide the backbone channel into a first sub-channel and a second sub-channel, to transmit the first channel packet provided from the first input packet buffer using the first sub-channel, to transmit the second channel packet provided from the second input packet buffer using the second sub-channel, and to transmit the third channel packet provided from the third input packet buffer using both the first sub-channel and the second sub-channel;
• and
• a receiving interface unit comprising:
• an output buffer having first through third output packet buffers;
• and
• a receiving channel management unit configured to store the first channel packet received through the first sub-channel into the first output packet buffer, to store the second channel packet received through the second sub-channel into the second output packet buffer, and to store the third channel packet received through both the first sub-channel and the second sub-channel into the third output packet buffer.
