【摘要】 ARM系列CPU以其体积小、功耗低、成本低、高性能的特点而得到广泛应用。对ARMCPU进行C语言编程需要启动代码。启动代码通常用汇编语言编写,用来引导C语言程序运行,并完成一些C语言不能或不便完成的功能。文中面向ARM7TDM I微处理器S3C4510设计,通过地址重映射技术,实现了一种能直接在RAM中运行、有中断向量表的启动代码,大大方便应用程序的开发。更多还原

【Abstract】 With the fast development of ARM and related technologies,ARM microprocessors have gained wide utility through its properties of having small size,low power consumption,low cost and high efficiency.Programming ARM CPU with C language needs boot code,witch is usually written by assemble language with the mission of starting the C language code and fulfilling some functions that can not be fulfilled by C language.Targeting at S3C4510 microprocessor,this paper presents a boot code for ARM that has vectors table and can run in RAM directly by the technology of memory spaces remapping.This will make the work of programming much easier.更多还原
