10. The NoC system according to claim 8 further comprising:
a safety controller configured to issue a signal in response to a fault detected; and
a data checker disposed between the safety controller and one of the master processing device and the slave data device.
11. The NoC system according to claim 10 , wherein the second set of NoC module includes a slave module duplicated from the first set of NoC modules, and the data checker is disposed between the duplicated slave module and the safety controller.
