TTP/C总线节点的备份与故障节点的再整合是提高总线可靠性与实用性的有效方法。参考TTP/C总线协议,在自主设计的基于Zynq的TTP/C总线控制器上设计了一种节点备份与再整合的方法,保证节点故障后可以重新整合进入集群,或者启用备份节点来保证集群的正常功能,最后通过试验验证了所设计的节点备份与再整合方法的有效性。 TTP / C bus node backup and fault node re-integration is to improve bus reliability and practicality of the effective method. With reference to the TTP / C bus protocol, a method of node backup and reintegration is designed on a self-designed Zynq-based TTP / C bus controller to ensure that the node can be reintegrated into the cluster after the fault occurs or the backup node can be enabled to ensure the cluster Finally, the validity of the proposed node backup and reintegration method is verified through experiments.
