Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A network-on-chip (NoC) system in a chip, comprising:
a default communication path between a master processing device and a slave data device, the default communication path configured to work in a normal operation state of the chip;
a first set of NoC modules disposed along the default communication path, the first set of NoC modules being operatively connected along the default communication path;
a backup communication path between the master processing device and the slave data device, the backup communication path configured to replace the default communication path when a fault arises in the default communication path;
a second set of NoC modules, the NoC modules in the second set being duplicated from one or more NoC modules in the first set, the second set of NoC modules being operatively connected along the backup communication path;
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.
