  • Apparatus for multiplexing Gigabit Ethernet frame and apparatus for demultiplexing 10-Gigabit Ethernet frame
    Publication number: 20050135434
    Abstract: Provided are an apparatus for multiplexing Gigabit Ethernet frames and an apparatus for demultiplexing 10-Gigabit Ethernet frames. The apparatus for multiplexing Gigabit Ethernet frames includes at least one pre-processing unit, a multiplexing unit, an SDR/DDR conversion unit, and a control unit. The at least one pre-processing unit receives Gigabit Ethernet frames, converts the Gigabit Ethernet frames into 10-Gigabit Ethernet frames, and outputs the 10-Gigabit Ethernet frames. The multiplexing unit receives the 10-Gigabit Ethernet frames, time division multiplexes the 10-Gigabit Ethernet frames in frame units, and outputs the time division multiplexed 10-Gigabit Ethernet frames as first data. The SDR/DDR conversion unit, which converts the first data into second data having two 32-bit bus structures and outputs the second data. The control unit outputs a first control signal in response to an output request of the pre-processing unit.
