摘　　要：在以32位处理器为核心、uClinux为操作系统的嵌入式系统中,Boot Loader负责初始化硬件设备、建立内存空间的映射图,从而将系统的软硬件环境带到一个合适的状态,以便为最终调用操作系统内核准备好正确的环境。44binit.s是S3C44B0X的BootLoader中不可缺少的最先运行的程序,它由ARM汇编语言编写,主要完成硬件设备的初始化。文章详细介绍了44binit.s的设计思路以及较难懂的一些程序段落。In the embedded system that having a 32bit CPU as its core and uClinux as its operating system, Boot Loader initializes hardware devices and sets mapping table of main store, so a perfect envi- ronment is supplied to startup operating system. 44binit. s is a essential and first running program in Boot Loader for S3C44BOX, it is compiled by ARM assemble language, and its function is initializing hardware devices. This text detailedly introduces the designing means and some program paragraphs difficultto comprehend.
