摘要
针对Windows平台下的传统非实时数据库实时性无法满足实时仿真需求问题,首先分析了RTX的特点,介绍了基于RTX的仿真平台。在此基础上,提出了一种在RTX和Windows的仿真平台下,利用RTX的实时特性以及内存管理特性,设计实时仿真数据库的方法。方法主要利用RTX的中断处理以及进程调度机制来提高Windows的实时特性,利用RTX的内存锁定技术来构建实时仿真数据库,采用传统的非实时关系数据库保存历史仿真数据,并由实时仿真数据库和历史数据库构成完整的仿真数据库。
Traditional database under windows can＇ t meet the requirement of real-time emulation system is mainly figured out. The characteristics of RTX are analysed, and also introduced a emulational platform based on RTX , then, a method of designing Real-Time emulational database based on Windows and RTX is also proposed. It mostly take advantage of the interrupt manager and process scheduler to improve Real-Time respond of Windows, and use the memory locked technique to construct Real-Time emulational database, also take traditional relation-database to storage history emulational data. The whole emulational database is composed of Real-Time emulational database and history database.
