摘要
ARM以其高性能、低功耗、易扩展的特点成为了嵌入式系统全球领先的16/32位RISC微处理器内核。但由于嵌入式系统中数据量的增加,对存储设备的要求也越来越高。在众多存储卡中,SD卡占有越来越多的市场份额。文中介绍了基于ARM7平台设计的SD卡读写系统,包括SD卡与LPC2292的硬件接口电路设计及相应的软件程序设计。
ARM, with its high performance, low power consumption, and flexible extension, is particularly suitable for designing embedded systems. With the increase of data in embedded systems, the requirement of storage device is even higher. Of the most flash memory cards, the SD card occupies more and more market quotas in the application. Based on the platform of ARMT, a SD card file system is designed, including the interface between LPC2292 and SD card and corresponding software system.
