摘　　要：相较于许多嵌入式操作系统,VxWorks操作系统有着更快的启动速度,但应用于武器系统,其启动速度依然有待提高。通过对VxWorks启动过程的研究,寻找影响启动速度的因素,最终提出了基于启动方式、Flash和内存的快速启动优化方案,实现了VxWorks在PowerPC上的快速启动。实验数据表明,使用该方案启动1580 kB的VxWorks内核仅需0.8 s,相比Vxworks正常启动时间近10 s,能够降低91%的启动时间。Compared with many embedded operating system,the VxWorks operating system has a faster boot-up speed.But it still needs to be improved for weapons system.On the basis of analyzing the boot-up process of VxWorks and searching the factors which affect the boot-up speed.A fast booting method based on boot mode.Flash and memory improvement is finally proposed,the fast boot of VxWorks is realized based on PowerPC.The experimental data show that it only needs 0.8 s to boot up a 1580 kB-sized VxWorks image.Compared with the normal booting time10,it reduces the total booting time by 91%.
