| 摘 要： | 根据仿真系统支撑平台的实时性要求，利用动态链接库和内存映射文件建立系统运行的实时数据库，通过内存映射文件开辟共享内存区，编制一系列封装在动态链接库的接口函数来实现对共享内存区数据的操作．该方法既能实现多个进程数据的共享，又保证了实时的响应速度．

| Abstract: | According to the real time requirement of the supporting platform of simulation system, this paper establishes the real time database in the course of system running through DLL and memory mapping file;sets up a sharing memory area by memory mapping file;and compiles some interface functions, which are embedded in DLL, realizing the operations of the sharing memory area. This method not only has realized the sharing of a lot of process data, but also guaranteed the prompt response speed. |
