A computer chip for connecting devices on a chip by using a star-torus topology is provided to realize fast operation by quickly transferring data with reduction of the number of hops passed when the data is transferred from one module to another module on the chip, and reduce design complexity and size of the chip by reducing the number of lines connecting the modules. A plurality of routers(410,420,430,440,450,460,470,480,490) are formed on the computer chip. Each router, using a virtual channel, is connected to the routers neighboring in an X/Y direction. The plurality of IPs(Intellectual Property)(411-413 - 491-493) are formed on the computer chip. Each IP is connected to more than one router. Each router is connected in a unidirectional circular topology to the X/Y direction and the number of routers is bigger than six. Each outer is connected to more than two IPs and each IP is connected to one router.
