首先,对比和分析了弹载计算机软硬件系统的设计方案,在Embest公司的Embest EDUKIT-Ⅲ实验平台上搭建了一个嵌入式开发平台,在Embest公司提供的BSP基础上,开发了弹载计算机软件所需要的板级支持包BSP,并在性能优化上给出了一些分析和改进。其次,根据弹载计算机系统的需求,将VxWorks与Linux做了分析和对比,重点分析VxWorks的实时性能。同时分析和总结ARM的体系结构,从软硬件两方面着眼,分析探讨整个弹载计算机软件系统性能上的优化和平衡。第三,根据系统实时性能的要求和前文的分析结果,提出了一些改进算法,设计和开发了弹载计算机软件系统的部分设备驱动和软件模块。最后,对系统的功能进行了测试,给出了测试数据,并利用Matlab/RTW实时仿真方法进行了整个系统的仿真试验。- It is to build an embedded development platform based on Embest EDUKIT-III, and to develop the BSP which the missile-borne computer software needed based on the BSP given by Embest Corporation, and to give some analyses and improvements on optimizing performance.Second, according to the system request, it made the analysis and contrast between VxWorks and Linux and then to analyze the real-time performance of VxWorks emphatically. Meanwhile it analyzed the ARM architecture, then made optimization and balance of entire software system by focusing from the software and hardware.Thirdly, according to request of the system real-time performance and preamble analysis result, it is to propose some improvement of algorithm. And it is to design and complete some drivers of devices, and also software module of the missile-borne computer.Finally, the system passes the test of the real-time simulated experiment of Matlab/the RTW
