Abstract:
A cell multiplexing device of an asynchronous transmission mode, comprising:a buffer unit which includes a plurality of cell buffers corresponding to input ports, for storing cells received through said input ports;a plurality of counters, each of said plural of counters respectively corresponding to a corresponding cell buffer, each if said plurality of counters respectively storing a number corresponding to cells stored in each of said cell buffers;a unit clock unit determining for each of said plurality of counters a count unit of cells stored in said plurality of cell buffers;a selector outputting control signals to select cell buffers in an order of selection of maximum values by comparing values of said plurality of counters for corresponding cell buffers; anda unit receiving said control signals, said unit receiving an output of said buffer unit and multiplexing cells from said buffer unit according to said control signals, said unit processing cells respectively stored in said cell buffers to be output from said buffer unit according to said order of selection of maximum values where most cells are stored.
