摘要
星载控制计算机的动态可重构设计是未来天基信息系统卫星载荷满足"软件无线电"设计概念的重要组成部分。本文在VxWorks操作系统平台基础上实现了星载控制计算机的动态可重构设计。本设计针对VxWorks动态加载组件的不足,通过建立模块信息表和模块间依赖关系表对模块动态加载、卸载、重载、替换、自动加载策略进行了改进设计,完善动态加载机制实现了星载控制计算机的动态可重构设计。
The dynamic reconfigurable design of on-board control computer has an important part in meeting the need of ＂software radio＂ design for the future space-borne information system satellite payload. This paper realizes the dynamic reconfigurable design of on-board control computer based on VxWorks platform. To overcome the shortage of the dynamic loading mechanism based on VxWorks, we improve the strategies design of module dynamic loading, unloading, reloading, replacing, auto-loading, by establishing module information table and relationship table between modules. It perfects dynamic loading mechanism and accordingly the dynamic reconfigurable design of on-board control computer is realized.
