摘要
S3C44B0X作为以ARM7TDMI为内核的微处理器得到广泛的应用；Blob因功能强大、使用方便、可移植性好而成为S3C44B0X开发板上非常适合uClinux的BootLoader。文中重点介绍了基于S3C44B0X的嵌入式系统在上电启动后应用程序或操作系统运行前,对处理器及其内部功能模块进行初始化的过程,并结合代码详细地分析了Blob的运行过程。
S3C44BOX Microprocessor which base on ARM7TDMI is extensively used, Blob becomes greatly fit uClinux on S3G44BOX because it has strong function, expedient use and easy Porting. This article stress the process of the inside registers and the function block of the ARM processor, after the embedded system has powered on before the run of operation system or application program, then by using the start up code of the S3C44BOX, thoroughly explain the blob, the startup process of the embedded system.
