OFDM_Verilog实现

专用的内存控制器是素数在不包含的微处理器的应用程序的重要性（高端应用）。内存控制器提供内存刷新指令信号，读取和写入操作和SDRAM的初始化。我们的工作将集中于ASIC双数据速率（DDR）SDRAM设计方法控制器位于DDR SDRAM和总线之间高手。控制器简化了SDRAM命令接口标准的系统的读/写接口，也优化的读/写周期的存取时间。双倍数据速率（DDR）SDRAM控制器使用Cadence RTL实现编译器。

基于FPGA的用verilog语言写的，改程序可产生不同调制系数和不同频率的AM波，长按按键切换调制度25 、50 、75 和短按按键切换调制信号频率1k、1.5k、2k、2.5k.(Based on the FPGA using verilog language, change the program can produce different coefficients and different frequency modulated AM wave, long press the button to switch the modulation of 25 , 50 , 75 and short press button to switch the modulation signal frequency 1k, 1.5k, 2k, 2.5k.)

级联积分梳状(CIC)滤波器是一种被广泛应用于软件无线电中，可以实现抽取或者插值的高效滤波器。它主要用于降低或提高采样率。CIC滤波器的主要特点是，仅利用加法器、减法器和寄存器，占用资源少，实现简单且速度高。

基于高清视频的3D人脸识别源代码，四万多行，经过FPGA实际验证，最近调试完毕。(The source code of 3D face recognition based on HD video, more than 40,000 lines, has been verified by the actual FPGA, and has been debugged recently.)

基于FPGA的32阶FIR数字滤波器设计 源程序。设计使用了并行乘法器，运行速度更快，占用内存更小，延迟更小。 (32 order FIR digital filter based on FPGA design source program. Design USES parallel multiplier, faster and less memory, less delay.)

用verilog语言编译的pci协议实现，而且有具体的电路图(Compiled with the verilog language pci protocol implementation, but also the specific circuit)

前段时间因项目需要编写了滑动相关运算的FPGA代码，并上板验证ok，现在发出来与大家分享

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.)
