verilog实现的1024位的大数模逆算法，引入RAM作为数据通道

本书共由三篇组成。其中第一篇由第1~3章组成，介绍PCI总线的基础知识。第二篇 由第4~13章组成，介绍PCIExpress总线的相关概念。第二篇的内容以第一篇为基础。(This book comprises a total of three components. The first chapter from the first 1-3 chapters, introduces the basics of the PCI bus. Second by the first 4 to 13 chapters, introduces concepts related PCIExpress bus. The contents of the first to second basis.)

基于vhdl的按键检测程序。可以有效消除抖动(vhdl key dectect program)

costas载波恢复算法 锁相环路，注释很清楚(costas carrier recovery algorithm PLL)

韩福柱老师FPGA实验源码，用vhdl语言在xilinx FPGA上实现，包括ad采集，温度传感器读取，秒表，跑马灯和按键次数统计4个实验(Han Fu teacher FPGA column experiment source code, vhdl languages on xilinx FPGA implementations, including ad acquisition, temperature sensor readings, stopwatch, marquees and keystrokes 4 experimental statistics)

说明：  使用FPGA实现中值滤波算法，能够使数据直接使用该系统对数据进行中值滤波。(FPGA is used to realize the median filtering algorithm, which can make the data directly use the system for median filtering.)

基于FPGA器件的DDS设计实现中的一个核心部分就是波形存储表的设计。首先采用LPM_ROM和 VHDL选择语句这两种方法进行波形存储表的设计和比较分析 然后考虑到硬件资源的有限性及DDS的精度要 求,对这两种方法的程序进行了优化 最后对这两种方法设计的程序进行仿真和硬件调试。结果表明:采用这两种 方法都能有效地实现DDS中波形存储表的设计。 (DDS-based FPGA devices designed to achieve one of the core of the waveform is stored in table design. First of all, choose to adopt LPM_ROM and VHDL statements of these two methods for the design waveform storage tables and comparative analysis and then, taking into account the limited hardware resources and the accuracy of DDS, the two methods to optimize the process the last of these two methods of process design simulation and hardware debugging. The results showed that: the use of these two methods are all effective ways to achieve the DDS waveform stored in the table design.)

步进电机控制程序，用vhdl实现。可实现电机的正反转控制-Stepper motor control program, using vhdl implementation. Positive inversion of motor control can be realized

反应速度测试小游戏，最小外设cpld游戏，带设计说明书(Reaction speed test games, the minimum peripheral cpld game, with design specifications)

说明：  基于Verilog语言编写的LCD1602显示的日历程序，类似时钟功能值得参考。(LCD1602 shows calendar program based on Verilog language, similar clock function is worth reference.)

基于fpga和51单片机的等精度频率计，通过fpga对信号进行采集，数据传给单片机计算，再由12864进行显示，可进行频率，周期，脉宽，占空比，幅值等的测量。(Fpga and 51 microcontroller based precision frequency meter, through fpga for signal acquisition, data to the microcontroller to calculate, and then by 12864 for display, can be measured frequency, period, pulse width, duty cycle, the amplitude and the like.)
