基于ARM的智能手持设备
摘要
的发展和后PC时代的到来,电子产品的小型化、智能成为了发展趋势,而智能化必不可少的就是操作系统,因此嵌入式系统已成为计算机领域的一个重要组成部分,并成今年来新兴的研究热点。
嵌入式系统的应用现在广泛应用在了高级引擎管理、保安系统、机顶盒、便携计算机和高档打印机等设备。
本文通过对嵌入式智能手持设备操作系统的分析研究以及根据不同CPU对内核以及u-boot的修改,来对嵌入式系统进行研究。
本文概括性的描述了嵌入式系统的概念、发展与特征,介绍了ARMS3C2440开发板的硬件核心——ARM920T嵌入式处理器。、功能裁剪、配置文件的修改、内核交叉编译过程以及内核在基于S3C2440处理器开发板上进行移植的关键问题等。还有对引导装载程序u-boot的源文件对S3C2440的支持修改以及编译移植过程。

Abstract
Along with the development and the latter PC time's arrival, Miniaturization of electronic products, smart became a trend and that is essential to intelligent operating system, so the embedded system has e puter domain a ponent, combines to make or es the emerging research hot spot this year.
Application of embedded systems is now widely used in advanced engine management, security systems, set-top boxes, puters and high-end printers and other devices.
Based on the embedded operating system, smart handheld devices as well as the analysis of the different CPU cores, as well as changes to u-boot in order to conduct a study on embedded systems.
Describes the general concept of embedded systems,the development and the characteristic introduced ARMS3C2440, which is the development board hardware core - - ARM920T embedded processor. Simultaneously, discussed in detail the kernel source files structure and function of cutting, the modified configuration file, the process of piling the kernel and the kernel S3C2440 processor based development board to carry out key issues such as transplants. There are procedures to guide the loading of the u-boot source files to support a revision of the S3C2440 and the transplant process .
