摘要
基于ARM的嵌入式系统和SD卡的应用越来越广泛。提出了一种基于SAMSUNG的S3C2410A嵌入式处理器平台上实现SDHost控制器的方法,并为该平台上运行的WindowsCE系统编写了驱动程序。对SD卡连续插拔导致的系统宕机问题,分别提出了延时采样和多次采样的软件防抖动的解决方法,并且进行测试和性能分析。
The application of SD card and embedded system based on ARM system become more and more popular. The implementation of the SD host controller based on Samsung＇s S3C2410A microprocessor platform are presented, its device drive for Windows CE is developed. The software implementation using delay-sample and multi-sample are introduced for system crash caused by card plugged in and plugged out continuously, the test and performance analysis are discussed.
