说明：  MATLAB的SIMULINK和FPGA联合设计滤波器等，摆脱了传统的代码设计。(MATLAB's SIMULINK and FPGA jointly design filters and so on, and get rid of the traditional code design.)

bch encoder+decoder 源代码，Flash控制器，通讯都需要用到哦-bch encoder+ decoder source code, Flash controller, communications are needed Oh

数字频率测量器，脉宽测量器。可测量多种频率波形的脉宽。(Digital frequency measurement device, pulse width measurement device. Measurement of the waveform of frequency pulse width)

verilog语言实在点变换DFT源代码，可以配合软核或者其他CPU进行综合FFT变换，也可以单独使用生成module！(verilog language is point FFT transform source code, can tie in with the soft-core CPU, or other integrated FFT transform, it can be used to generate module!)

快速傅立叶变换(FFT)作为时域和频域转换的基本运算，是数字谱分析的必要前提。传统的FFT使用软件或DSP实现，高速处理时实时性较难满足。FPGA是直接由硬件实现的，其内部结构规则简单，通常可以容纳很多相同的运算单元，因此FPGA在作指定运算时，速度会远远高于通用的DSP芯片。FFT运算结构相对比较简单和固定，适于用FPGA进行硬件实现，并且能兼顾速度及灵活性。本文介绍了一种通用的可以在FPGA上实现128点FFT变换的方法。设计复数乘法器为核心设计了FFT算法中的基-2蝶形运算单元，溢出控制单元和地址与逻辑控制模块等其它模块,并以这些模块和FPGA内部的双口RAM为基础组成了基-2FFT算法模块。 

这段代码是用来实现二维高斯滤波器的。
