摘要
以ARM微处理器LPC2290作为硬件核心,设计和实现了一种基于ARM和MiniGUI的嵌入式信息检索系统。将网络通信与MiniGUI相结合,以C/S结构访问远程MySQL数据库,提出了系统的软硬件体系结构,设计了基于MiniGUI的图形用户界面和数据检索模块程序,阐述了系统设计中的若干关键实现细节。结合32位高性能的ARM处理器和嵌入式uClinux操作系统,完成了系统应用程序在ARM目标板上的移植。所设计的系统有效地改善了人机接口,能够满足信息检索的应用要求,可弥补传统信息检索终端成本高的不足。
With ARM microprocessor（LPC2290） as a hardware core,an embedded information retrieval system based on ARM and MiniGUI was designed and realized.Combined with network communications and MiniGUI technologies,the system′s software and hardware architecture was put forward,graphical user interface module based on MiniGUI and data retrieval procedures were designed by accessing to remote MySQL database with Client/Server structure,and some key implemented details were discussed.Combined with 32-bit high-performance ARM processor and uClinux embedded operating system,the system application program was ported to ARM target.The system improves the human-machine interface efficiency,and satisfies the information retrieval application requirements.It can make up for the traditional information retrieval terminal shortcomings at high cost.
