摘要

Flash板载容量一般较小，SDRAM掉电后数据会丢失，并且不能方便地将数据传输到计算机上。为了满足图像处理系统中大容量的存储需求，本文采用CF卡作为可移动存储介质。主要介绍了CF (Compact Flash)卡的工作原理和FAT16文件系统的工作原理，实现了DSP和CF卡接口电路的软硬件设计，编写了CF卡和FAT16文件系统的底层驱动。

Research of DSP file system based on CF card

The capacity of Flash on-board is generally small, the data will be lost after SDRAM power-down, and they can not easily transfer the data to a computer. In order to meet with large-capacity storage needs in the image processing system, this paper uses CF card as removable storage media. It mainly introduces the working principle of CF (Compact Flash) cards and the principle of FAT16 file system, achieves the hardware and software design of the DSP and the CF card interface circuit, compile underlying drive of the CF card and FAT16 file system.
