【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.更多还原
