The invention discloses a path diversity-based crossbar switch fine-grit fault-tolerant module in a network on a chip and a method thereof, and the crossbar switch fine-grit fault-tolerant module and the method are applied to a router which consists of five input ports, a routing computation module, a crossbar switch distribution module and five output ports. The crossbar switch fine-grit fault-tolerant module comprises a BIST detection unit, a fault-tolerant unit, an additional control unit and a crossbar switch. Through fine grit, different fault conditions of a data distributor, an internal link and a data selector in the crossbar switch are considered; the fault-tolerant unit is used for carrying out fault tolerance on the faults of the data distributor and the internal link, and enabling a fault-tolerant path to be diversified; meanwhile, the data selector is added to carry out fault tolerance on the data selector. According to the crossbar switch fine-grit fault-tolerant module and the method, normal data transmission can be carried out at the cost of relatively small hardware expense under the condition that the crossbar switch is high in fault rate, so that the network throughput is improved.

Embodiments of the present application provide a resident state detection method, apparatus, and device. In this method, the electronic device performs anomaly detection on the resident state when the non-connected state service card occupies hardware resources to execute the disconnected state service and the connected state service card occupies the hardware resources to execute the connected state service; if If the abnormality detection result is that the resident state is in an abnormal state, RRC reconstruction is triggered. When the connected state service card restores the connected state service, the abnormality detection of the parked state can be carried out in time, and when the abnormality detection result is that the parked state is in an abnormal state, the RRC reconstruction can be triggered in time, which can quickly identify the abnormal state of the parked state, so that the The connected service card normally performs data transmission.
