摘　　要：随着嵌入式系统的不断发展,BOOTLOADER程序开发和移植工作的复杂度越来越高,严重影响了嵌入式系统的开发进度。通过对BOOTLOADER程序引导过程的深入分析,从功能实现、运行过程和代码结构3方面展开研究,提出了一种通用BOOTLOADER架构,并在Power PC平台上完成了架构的实现,验证了其正确性和易用性,能够有效地提高BOOTLOADER程序的开发和移植效率,进而缩短整个嵌入式系统的开发周期,对BOOTLOADER程序的开发和移植工作具有指导性意义。With the continuous development of embedded systems,the development and transplantation of BOOTLOADER program become more and more complex,which affects the development progress of embedded system seriously. Based on the analysis of the process of the BOOTLOADER program,a general BOOTLOADER architecture is proposed from the aspects of function realization,running process and code structure. And the implementation of the architecture is completed on the Power PC platform,which verifies the architecture' s validity and usability. This architecture can effectively improve the efficiency of BOOTLOADER programs' development and transplantation,thereby shortening the development cycle of the entire embedded system. It is instructive for the development and transplantation of the BOOTLOADER program.
