摘要
为保证多层级余度架构飞管计算机的正常运转,针对其复杂的硬件结构提出了一种简单高效的同步算法。算法采用“机箱间-通道内”两级同步机制,即完成机箱层级的同步,从而为单台机箱内所有节点提供一个基准时间线。以此基准线进行单台机箱内各个通道的同步工作,进而实现产品内所有节点间的同步。算法不需要整台产品内每两个节点间都设计有同步总线,简化了软硬件结构的复杂度,提升了同步算法的效率,可作为复杂余度架构飞管计算机同步算法的参考方案。
This paper proposed a simple and efficient synchronization algorithm for a multi-level redundancy architecture vehicle management computer with the complex hardware structure to ensure its normal operation.The algorithm adopts a two-level synchronization mechanism of"inter-chassis intra-channel",which first completes the synchronization at the chassis level,thereby providing a baseline timeline for all nodes within a single chassis.Using this baseline to synchronize all channels within a single chassis,thereby achieving synchronization between all nodes within the product.This algorithm does not require a synchronization bus to be designed between every two nodes in the entire product,simplifying the complexity of software and hardware structures,improving the efficiency of synchronization algorithms,therefore can be used as a reference solution for complex redundancy architecture vehicle management computer synchronization algorithms.
