Switching device of Networks on Chip and scheduling method thereof

Switching devices of the network-on-chip system, and is disclosed in his scheduling method. Switching devices of the network-on-chip system according to the present invention, the plurality of input ports and a plurality of output switching unit having a port, and an input port and output an input port set a transmission path between the ports, and holds the data of the plurality of input ports determining a code length based on the number and the code length determined to the input port and the output port corresponding to the set transmission path includes a scheduler for assigning a predetermined code. As a result, since the flexibility to determine the code length depending on the transmission number of packets, it is possible to improve the performance of the switch. CDMA switch, scheduler, arbiter round robin
