用VHDL实现的FFT,经过测试，效果很不错！值得一看-Use vhdl to do fft，after test，we can see the result is very good!

应用背景以太网交换机所使用的以太网控制专用芯片多具有SMI接口,以实现对芯片的控制。考虑到以太网交换机的节能趋势,使用ARM芯片s3c2440作为以太网专用芯片的主控器件,使用软硬结合的方法,设计并实现了单片机系统与SMI接口的通信,介绍了SMI接口的特征和时序,并以以太网控制芯片88E6097为例,给出了在ARM芯片s3c2440上用I/O实现SMI接口的硬件电路和相关程序。关键技术基于c语言的SMI接口模拟，88E6097交换芯片的寄存器读写访问，88E6097芯片VLAN技术。采用ARM芯片s3c2440基于Linux的操作系统，通过c语言编程模拟SMI接口，对88E6097交换芯片的寄存器进行读取、写等操作，以达到对88E6097交换芯片基于802.1Q的VLAN配置。

用simulink工具对OFDM进行仿真。BPSK作为例子，其它的可修改-Simulink tools used to simulate OFDM. BPSK as an example, the other may be amended

name=CustomInputBox ver=v1.0 author=ccrun devtool=C++Builder fullsource=1 desc=通过自定义消息的方法来实现自定义输入框-name CustomInputBox ver = = = v1.0 author cc run devtool = C = Builder fullsource desc = 1 through self- justice information and means to achieve self-definition input box

应用背景主要是应用在电子射频、通讯等行业，例如采样中的数字本振信号、接收机的发射信号等等，还可以用做测试中做一个幅值可调的信号发生器，频率源等，为测试和设计带来很大的帮助关键技术数字信号发生器   DDS  频率可调 。运用MATLAB生成相关 的原 始数据，根据按键改 变频率 控制字，不断地累加，就可以实现频率可调。将生成的二进制代码发送给对应的DAc芯片的数据接口，通过给后端的模拟信号进行简单的硬件上的滤波，即可解决信号的高次谐波。
