目前国内有关数字信号处理的教材在讲解快速傅里叶变换（FFT）时，都是以复数FFT为重点，实数FFT算法都是一笔带过，书中给出的具体实现程序多为BASIC或FORTRAN程序并且多数不能真正运行。鉴于目前在许多嵌入式系统中要用到FFT运算，如以DSP为核心的交流采样系统、频谱分析、相关分析等。本人结合自己的实际开发经验，研究了实数的FFT算法并给出具体的C语言函数，读者可以直接应用于自己的系统中。--I implemented FFT algorithm in real number and provides a C function. Users could use it directly in their systems.

HFAT32 v1.0是我依据FAT标准,按照自己的理解写出来的一个FAT文件系统 特性: 1.HFAT32 v1.0 是一个小型的嵌入式FAT文件系统,可以方便地在nand flash,RAM和SD Card等 存储设备上创建FAT文件系统和操作它. 2.目前支持FAT16/32,支持长文件名.-I HFAT32 v1.0 is based on FAT standards, according to their own understanding of written in a FAT file system characteristics: 1.HFAT32 v1.0 is a small embedded FAT file system, can be easily in the nand flash, RAM and SD Card such as storage devices to create a FAT file system and operating it .2. currently supports FAT16/32, support long file names.

该工程是从ecos嵌入式系统下移植过来的一个小型的fat16文件系统，让他在win32下可以运行，来测试其正确性，改工程可以很好的移植到其他嵌入式平台上，比如手机，手提电脑平台上，其小巧实用行应该有一定的商业价值。 拜托斑竹给号了。- This project is inserts a small fat16 filing system from ecos which under the type system transplants, enables him to be allowed to move under win32, tests its accuracy, changes the project to be allowed to insert in the type platform the very good transplant to other, for instance the handset, in the portable computer platform, its exquisite practical line should have the certain commercial value. Asked the spot bamboo to give the number.
