The rapidIO technology is widely applied to a comprehensive electronic information system due to high-speed transmission between chips and modules.
The current integrated electronic information system mainly comprises a general Data Processing Module (DPM), a general Signal Processing Module (SPM), a network switching module (RCM), an IO module and the like, and adopts a rapidIO interconnection bus protocol between chips and boards to realize high-reliability data transmission. One or more domestic SRIO exchange chips are deployed in the network exchange module, the IO module and the data processing module to form a transmission frame based on the rapidIO network.
The SRIO nodes in the integrated electronic information system have the conditions of dynamic network access and network withdrawal, and are similar to timely connected and timely used scenes in the Ethernet. The existence of dynamic network access and network withdrawal of the SRIO nodes realizes the detection of events by the port of the domestic SRIO exchange chip in the network exchange module. And reporting a port-write packet through each port of the domestic SRIO exchange chip, and correspondingly processing the reported event by the main control module, thereby completing the management of the whole rapidIO network node.
The port of the domestic SRIO exchange chip continuously reports a port-write packet to the main control module, which is called event report. The cpu of the master control module is always preempted to process the port-write packet and cannot process other things. The event report can be caused by the following conditions:
1) In the system, the voltage of the module where the RIO node is located is unstable, which may cause event report.
2) Under the condition of low temperature or high temperature, part of domestic devices have poor link quality, and event report can be caused.
