异步FIFO的设计 包括testbench 已调试成功

第十一章到第十三章的代码 本书通过100多个模块实例，详细地讲解了Verilog HDL程序设计语言，全书共分13章，内容涉及VerilogHDL语言基本概念、建模、同步设计、异步设计、功能验证等，实例包括各种加法器/计数器、乘法器/除法器、编码器/译码器、状态机、SPIMaster Controller、I2C Master controller、CAN ProtocolController、Memory模块、JPEG图像压缩模块、加密模块、ATA控制器、8位RISC-CPU等及各个实例模块相应的Testbench，所举实例具有很强的实用性和代表性，每个实例均给出了介绍、功能分析、程序代码和结果演示。(Chapter XI to the 13th chapter of the code in this book through more than 100 module instance, explain in detail the Verilog HDL programming language, the book is divided into 13 chapters, covering basic concepts VerilogHDL languages, modeling, synchronous design, asynchronous design, functional verification, etc. Examples include a variety of adder/counter, multiplier/divider, encoders/decoders, state machines, SPIMaster Controller, I2C Master controller, CAN ProtocolController, Memory modules, JPEG image compression module, encryption module, ATA controller, 8-bit RISC-CPU, etc. and the various instances of the corresponding module Testbench, The examples are highly practical and representation, each instance of it all gives the introduction, functional analysis, program code and results presentation.)

说明：  控制步进电机转动，正反转，旋转角度完美掌握。很好用，亲测(Control stepping motor rotation, positive and negative rotation, perfect control of rotation angle. Very easy to use, personal test)

代码是一个复数乘法器，两个复数相乘，只用到了2个实数相乘，运算量少(Code is a complex multiplier, two complex multiplication, uses only real number multiplied by 2, operations less)

基于stm32开发平台的，模拟ad采样程序设计，可直接下载使用(stm32 zhijiexiazaishiyong)

适用于FPGA的SOPC方面的元器件添加，如COMPNENT-Applicable to FPGA-SOPC area to add components, such as COMPNENT

采用vhdl代码描述自适应滤波器，具有很好的可参考性，和实用性(Vhdl code to describe the use of adaptive filter, can be found with a good nature and usefulness of)

ANALYSIS OF D-FLIPFLOPS

多功能数字钟，1、采用24小时制：时、分、秒计时、显示。 2、具有手动校准功能：分为时校准、分校准。 3、秒复位 4、闹钟功能 5、整点报时：仿中央人民广播电台整点报时信号

一位加法全加器，可以实现低位进位输入和高位进位输出。(full adder)

说明：  FPGA实现PLL锁相环，输出不同频率的时钟控制信号。(FPGA realizes PLL and outputs clock control signals of different frequencies.)
