| 摘要: |
| 综合模块化航空电子系统（IMA）的时间同步设计是系统设计的一项重要内容。针对
典型的IMA系统，提出了一种“软件授时、硬件同步”的时间同步方法，同步精度达到微秒
级。
该方法实现简单，可直接应用于工程化的IMA系统时间同步设计。 |

| Abstract: |
| Time synchronization design is an important aspect of Integrated M
odular Avionics(IMA) system design. Based on a typical IMA system, a “software
timing, hardware synchronizing” time synchronization method is proposed
and the synchronization precision can reach microsecond level. This method
is easy and can be directly implemented in the engineering of IMA sy
stems. |
