| 摘 要： | 针对AS5643总线传输等时数据包时所带来的不确定性问题,提出一种将总线周期分为等时和异步两部分时隙的优化传输方法,能在不影响确定性的前提下引入等时数据包传输。首先对引起不确定性问题的原因进行了分析,然后详细介绍了优化传输方法的原理及工程实现。该优化传输方法经实验证明是正确可行的,可应用于高度综合化的航空电子系统中。

| Abstract: | For the indeterminate question of transmitting isochronous packet by AS5643 bus, an optimization method is proposed by dividing a cycle into isochronous and asynchronous slot parts, which can transmit isochronous packet without disturbing the asynchronous transmission. This article analyzed the indeterminate question at first, and then explained the optimization transmission method and the implementation in detail. Experiments have been done to show the correctness of the optimization method, and this method can be used in integrated avionic systems. |
