Research And Implementation Of Technology For Data Storage Management In Embedded System Of Navigation Display And Control Platform

Based on optimize estimate methods and centered on electronic computer, a system which combined some or whole navigation equipments on carrier into one organic system was called Integrated Navigation System(INS).This kind of integration method can enhance the precision of navigation data and extend the function of single equipment or sub system.Taking Integrated Navigation System as the background, this paper introduces the phylogeny, actual status and character of INS, and update the memory system software's OS platform and extend the functions of the application aiming at the INS been developing in our school. Based on VxWorks 5.5 OS and File System, a set of new INS display console is realized. Taking advantage of advanced software techniques, this method enhances the whole performance of integrated navigation system.The embedded system software development technique, include the constitution principles and characters of RTOS is introduced detailedly. VxWorks and it's integrated development environment include the cross development mode and architecture of Tornado, the principle and design methods of device driver under VxWorks are carefully discussed.According to the need of INS's data storage ,the speed of data storage and data share,the driver of IDE,NAND Flash and USB under VxWorks is successfully solved.
