　　Windows CE是微软为嵌入式设备打造的操作系统，而嵌入式设备可谓多种多样，这就要求CE操作系统必须是可定制的，所以微软将Windows CE设计为模块化的操作系统。说简单点，我们可以把Windows CE想像成一盒积木，你可以用积木搭建出任何物体，但不一定要把所有的积木都用上-Microsoft Windows CE for embedded devices to create the operating system, which has many embedded devices, which requires CE operating system can be customized, so Microsoft Windows CE for the modular design of the operating system. That simple point, we can imagine Windows CE into a box of building blocks, you can use the modular structures any objects, but not necessarily to put all the building blocks are used

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.

无线下载更新程序功能，在zigbee的应用中非常有用，现在的厂商包括TI freescale等厂商号称可以但都未提供该功能或者该功能还很不成熟，上传的是基于5139芯片的无线下载更新功能程序，非常实用。-Wireless download the update feature in zigbee application is very useful, and now manufacturers and other vendors, including TI freescale claims may, but failed to provide the feature or the feature is still immature, the upload is based on the 5139 chip wireless download the update feature program, very useful.
