Low-cost fault-tolerant switch allocator for network-on-chip routers


Reliable operation that can be checked on-line is of paramount importance to current and future systems-on-chips that are implemented in very deep submicron technologies. In such systems, the communication among architectural modules is handled by a modular network-on-chip infrastructure that should be sufficiently protected from transient faults that may affect its correct operation. The error protection mechanism should cover all fault scenarios and incur the minimum area/energy/delay overhead. In this paper, we propose such an on-line checking mechanism for the switch allocator of the router that detects every possible single transient or permanent fault in the arbiters and handles it appropriately, thus preserving the reliable operation of the switch.
