IIR数字滤波器的测试文件（txt文本作为滤波器的输入，滤波器的输出保存至txt）

用verilog语言实现基于DDS技术的余弦信号发生器，其输出位宽为16比特(Verilog language cosine signal generator based on DDS technology, the output bit width is 16 bits)

FPGA／CPLD技术是近年来计算机与电子技术领域的又一场革命。本书以Xilinx与Altera公司的FPGA／CPLD为主，详细介绍了FPGA／CPLD从芯片到MAX+plusⅡ、Quartus与ISE开发环境和Verilog／VHDL语言，并以交通灯逻辑控制、电子钟与点阵LED显示、LCD液晶显示及计算机ISA接口和PCI接口的设计等为例，由浅入深地详述了如何应用FPGA／CPLD进行电子设计。书中的大多数电路图和源程序已经过实例验证，读者可以直接应用于自己的设计。本书的特点是强调实用性和先进性，力求通俗易懂。 本书适用于计算机、电子、控制及信息等相关专业的在校大学生，对广大工程技术人员也具有实用价值。(FPGA/CPLD technology in recent years the field of computer technology and electronic another revolution. Book Xilinx and Altera' s FPGA/CPLD based, detailing the FPGA/CPLD from the chip to MAX+plus Ⅱ, Quartus and ISE development environment and Verilog/VHDL language and logic control traffic lights, electronic bell with dot matrix LED display , LCD liquid crystal display and computer ISA interface and PCI interface design, for example, progressive approach to detail how the application of FPGA/CPLD for electronic designs. Circuit and the source of most of the book have been instances of verification, the reader can be directly applied to their own design. Characteristic of this book is to emphasize the practical and advanced, best straightaway. This book applies to computers, electronics, control and information and other related professional college students, the majority of engineering and technical personnel also has practical value.)

说明：  基于FPGA的任意波形发生器DDS,verilog编写，正常使用(Arbitrary waveform generator DDS based on FPGA)

基于System Generator的图像处理工程,多媒体处理FPGA实现的源码,图像形态学部分,腐蚀,膨胀,细化算法(System Generator based image processing engineering, multimedia processing FPGA implementation source code, image morphology section, corrosion, swelling, thinning algorithm)

本代码是基于可编程门阵列flield视频图形阵列实现。该代码是使用Verilog

基于 quartus 2 的 lte 信道估计verilog hdl代码 只有功能仿真 时序仿真自己加sdc文件并且调整testbench的clk才能做出来(Estimated Verilog HDL code based Quartus lte channel only functional simulation timing simulation plus sdc file and adjust the testbench clk to do it)

基于Verilog HDL出租车计费系统的研制(Based on Verilog HDL Taxi Accounting System)
