定时器加数码管显示源码，以及test bench测试模块源码，经modelsim仿真结果正确(Timer plus digital display source code, and test bench test module source code, by modelsim simulation results are correct)

说明：  FPGA控制AD7321的模块，是本人亲自试验过的。有Verilog源码，和简单文档。(FPGA control module of the AD7321 is personally tested. There Verilog source code, and simple document.)

说明：  Actel 8051 Verilog core

很好的学习FPGA嵌入式的资料！适合初学者和工程师参考！(Good learning FPGA embedded information! Suitable for beginners and engineers reference!)

用verilog编写的can总线控制器，包括设计参考历程和仿真程序，以及开发文档！(Written by verilog can bus controller, including the design reference course and simulation program, and the development of the document!)

Verilog RS232代码， 分为三个模块，时钟产生模块，发送数据模块，接收数据模块。 整个工程的功能是，你从串口上位机发送什么数据，串口就将该数据重新发送回上位机

通过代码控制音频编/解码硬件芯片WM8731， 通过按键控制音频输出的音量(Audio codec hardware chip WM8731 is controlled by code, and audio output volume is controlled by keys.)

The PID controller IP core performs digital proportional–integral–derivative controller (PID controller) algorithm. The algorithm first calculates the error between a measured value (PV) and its ideal value (SP), then use the error as an argument to calculate the manipulate value(MV). The MV will adjust the process to minimize the error. It can be used to calculate duty cycle for PWM (Pulse Width Modulation).

CSC RGB2YUV Verilog source code

此是进行循环冗余效验的Verilog编码，适合多种标准，如CRC16(this Cyclic Redundancy is well-tested Verilog code for a variety of criteria, such as CYXLIC REDUNDANCY)
