Apparatus and method for routing path setting between routers in a chip

The present invention using a plurality of intelligence from the device and the one-chip systems (SoC) having an n × n net topology-based structure consisting of the switches corresponding to the respective intelligent device, at least one switch having a unique address between intelligent devices of it proposes a scheme for setting a routing path in a switch to transmit and receive data. To this it is allocated an orthogonal code to maintain orthogonality according to the transmission directions of the data. Determining a transfer direction of transmission of the data, and to spread the data by setting up a routing path by using the orthogonal code assigned to the determined transfer direction. SoC, switches, code division, a routing path
