摘 要: 随着计算机技术的发展,嵌入式系统已成为计算机领域一个重要组成部分,并成为近几年来的研究热点。与此同时,作为嵌入式系统中的重要产品——pda也随着嵌入式操作系统的发展而不断提高。 本文提出并研究、设计了基于arm-windows ce的嵌入式产品平台。该系统的硬件在cadence公司的orcad和mentor公司的poverpcb5.0环境下开发,采用高速pcb设计方法,考虑抗干扰问题,以保证系统硬件的可靠性。系统充分利用arm处理器高性能、低功耗、低成本的优点。在嵌入式最小系统的基础上扩展了电池充电、mini usb、sd卡、lcd触摸屏、蓝牙、数字收音、音频编解码等pda专用功能模块。 完成构建硬件平台后,阐述了本pda系统板级支持包的设计与开发,包括bootloader和部分模块的驱动设计。 论文中介绍的硬件和软件平台可以作为嵌入式pda二次开发平台,为实际应用提供很好的开发起点。 With the development of computer technology, embedded system, being the center of interest in the rising research in recent years, has been becoming an important component in this field. At the same time, PDA /(personal digital assistant/), as one of the most important products from embedded technology, is becoming better and better with the development of the embedded systems. In this dissertation, an ARM-Windows CE based embedded product platform is proposed designed and realized. This hand-held PDA system is developed based on Samsung's S3C2440A micro-controller. The hardware is designed by virtue of OrCAD9.2 and PwerPCB5.0, which are two power EDA tools in the product family of harderware design tools. Strategies for high-speed board designment are considered for anti-jamming. Special interfaces of PDA are designed included manager of charger, mini USB, SD card, LCD, Blue-tooth, FM radio and audio CODEC. After building harderware platform of PDA, BSP of the PDA and drivers of some function modules are discussed. The platform of hard-ware and soft-ware presented in this dissertation can be used as secondary development platforms of embedded PDA and they provide excellent beginning for practice application.
