摘要
本文在充分考虑星载硬件平台性能的基础上,结合现有的UnQLite小型嵌入式数据库系统,提出了一种针对BM3803嵌入式处理器的数据库移植方法,省略了操作系统带来的开销,完成了具体的移植工作,介绍了部分源代码实现过程,测试验证表明,该方法正确可行,同时为星载嵌入式系统中的数据管理相关技术提供了新的解决方案。
In the paper,the existing UnQLite small-scale embedded database system is integrated based on the full consideration of the performance of the on-board hardware platform.A database migration method for the BM3803 embedded processor is proposed.The overhead caused by the operating system is omitted,the specific porting work is completed,and some of the source code implementation procedures are illustrated.After testing and verification,this method is correct and feasible.At the same time,it provides a new solutions for data management related technologies in embedded systems in space.
