VHDL常用源程序，希望以EDA技术学习者有用！-VHDL source code commonly used, I hope to EDA technology learners useful!

Verilog code to calculate Sobel

说明：  用VERILOG实现的，hdb3编码器和解码器，经过前仿真和后仿真成功(Achieved with the VERILOG, hdb3 encoder and decoder, after a successful pre-simulation and post simulation)

4 bit convoltion with vhdl.

二维DCT，FPGA实现JPEG压缩中的二维DCT(dct)

利用FPGA，产生三相SPWM波，与后继硬件电路配合，形成三相电源。高效，实用。(Using FPGA, produce three-phase SPWM wave, with subsequent hardware circuit with the formation of three-phase power. Efficient and practical.)

Farrow 滤波器设计经典文章，作者是：FM.Gardner，farrow滤波器设计的始祖，经典值得推荐！（两篇文章）(Farrow filter design classic article, the author is: FM.Gardner, farrow filter design ancestor, classic worth recommending! (Two articles))

完整的GMSK调制及维特比译码，程序中包括了高斯滤波器的设计，调制相位的计算，并采用了维特比译码算法解调出原始码元，最后计算了其误码率。(Complete GMSK modulation and Viterbi decoding, the program includes a Gaussian filter design, the calculation of the phase modulation, and uses the Viterbi algorithm demodulates the source element, the final calculation of the bit error rate.)

注意：是verilog语言写的 一bit的全加器，实现4位数的串行加法器，一个时钟能完成一次一bit的全加(Note: It is verilog language to write a bit full adder, to achieve four-digit serial adder, a clock can be completed once a bit full adder)
