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.

ISP for STR73X 默认情况下, bank0 是映射到地址0x00. 考虑到,IAP程序需存储在bank1,而用户程序需存储在bank0. 因此须使用CAPS工具,将bank1映射到地址0x00. 另外, 在IAP程序运行期间,必须在执行用户程序跳转之前,通过程序将bank0重映射到地址0x00(注:IAP程序已经实现了bank0重映射到地址0x00,用户不需要自己来编写代码).-ISP for STR73X default, bank0 is mapped to address 0x00. Taking into account, IAP process is stored in the bank1, while the user program to be stored in bank0. It is necessary to use the CAPS tool bank1 mapped to address 0x00. In addition, IAP procedure during operation must be in the implementation of user program before Jump through the procedure will bank0 re-mapped to address 0x00 (Note: IAP program has achieved bank0 re-mapped to address 0x00, the user does not need to write their own code).
