基于XScale PXA255军用PDA的硬件设计与实现
摘要
本论文的工作是设计并实现一个军用PDA系统。具体工作根据实际的项目需要,在对主流PDA的微处理器和外围器件的深入分析和研究后,选用Intel公司的XScale PXA255微处理器作为系统核心,设计了一种军用PDA实现方案,并按照要求制作了样机,经过系统调试和试运行,结果证明此设计方案可行。由于ARM系列微处理器得到多种操作系统的支持,此设计方案既可以作为普通PDA使用,也可以通过增加适当的功能模块用于其它方面。与目前市场上的军用PDA相比较,具有高性能、多功能等特点。
本文总结了在研制基于XScale PXA255微处理器的军用PDA硬件系统过程中完成的一系列具体工作。
This dissertation presents a military PDA system. By the requirement of the project,we selected Intel XScale PXA255 Microprocessor after studied many mainstream microprocessors. According to the specification on the design ,we proposeed the desigen scheme and made a prototype. The experiments have shown that it is feasible and works perfectly.Because the ARM family microprocessors are supports by many operating system,so it can be used as general PDA. Furthermore ,it has extensive usage through adding functional module.Comparing with the military PDA in the matket,it has performance and more function.
This paper summarizes a series of work in process of developing hardware system of military PDA based on XScale PXA255 microprocessor.
