Abstract:
1. An apparatus for multiplexing Ethernet frames, the apparatus comprising: a plurality of parallel pre-processing units, which receive Gigabit Ethernet frames, convert the Gigabit Ethernet frames into 10-Gigabit Ethernet frames, and output the 10-Gigabit Ethernet frames; a multiplexing unit, which 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; an SDR/DDR conversion unit, which converts the first data into second data having two 32-bit bus structures and outputs the second data; and a control unit, which outputs a first control signal in response to an output request of one of the pre-processing units, wherein the one of the parallel pre-processing units receives the output request for a 10-Gigabit Ethernet frame according to the first control signal and each of the parallel pre-processing units send the 10-Gigabit Ethernet frames to the multiplexing unit, without synchronization between the 10-Gigabit Ethernet frames that are output from each parallel pre-processing unit.
