摘　　要：VxWorks操作系统是美国风河(WindRiver)公司的一款嵌入式实时操作系统(RTOS),被广泛应用于通信、军事、航空航天等实时性要求极高的领域中;而OMAP处理器则兼容DSP内核和ARM处理器,具有广泛的应用领域。本文基于OMAP5910处理器架构和VxWorks操作系统的体系结构,将VxWorks移植到OMAP平台上。即根据OMAP5910的存储器地址空间映射关系和硬件资源配置,修改VxWorks操作系统的BSP相关文件,包括系统异常处理、CPU初始化、串口驱动和网络驱动的修改并加载等,并编译成内核镜像,将其移植到OMAP5910的ARM端。最后通过相应的测试点检测移植结果。VxWorks operating system is an embedded real-time operating system（RTOS）and sold by Wind River Systems of Alameda,California,USA.It is applied in the fields which ask for high real-time features like signal communication,military,aviation,space flight and so on;On the other side,OMAP processor contains DSP kernel and ARM processor,and it has widespread application fields to use.This article transplants VxWorks to OMAP platform according to the structures of OMAP5910 processor and VxWorks operating system.First according to the memory address space mapping relations and hardware resource configure of OMAP5910,BSP of VxWorks is modified,including system exceptional operations,CPU initialization,serial driver,network driver and so on.Then the kernel image is compiled,and transplanted to the ARM side of OMAP5910.At last the system is verified correct by some corresponding test points.
