| 动态重构是一项充分利用软硬件资源的技术。在介绍民机CNS系统和动态重构基本原理基础上，给出了一种动态重构的通用功能模块的设计方案，描述了利用有限状态机和排列组合原理计算系统配置的方法，并根据系统资源状况和应用的优先级对资源进行初次分配及再分配，设计出了一种动态重构算法，该算法能很好地兼顾资源备份式重构和资源抢占式重构。同时，指出对动态重构的品质设计需从可用性、可靠性、维护性方面考虑。最后，使用Simulink对动态重构算法的正确性进行了仿真验证。 |

| Abstract: |
| Dynamic reconfiguration is a technology which makes full use of software and hardware resource.The communication,navigation and surveillance(CNS) system of civil aircraft and the basic principle of dynamic reconfiguration are introduced,then a common function module for dynamic reconfiguration is presented.The calculation method for the system configuration is described by using a finite state machine and permutation and combination theory, and according to the state of system resources and priority of application for the primary and secondary allocation of resources,a dynamic reconfiguration algorithm is designed,which can effectively consider resource backup reconfiguration and resource preemption reconfiguration.It is pointed out that the usability, reliability and maintainability should be considered in quality design for dynamic reconfiguration. Finally, the correctness of dynamic reconfiguration algorithm is verified through Simulink′s simulation. |
