这是我自己写的4人表决器源码，在xilinx Spartan3E 上已经调试成功，拿出来与大家分享！...

基于VHDL语言的循环码编码器的程序，以一个（15，6）循环码为例-VHDL language based on the cycle of the program code encoder to a (15,6) cyclic code as an example

提供了《自己动手写CPU》本书每一章涉及的OpenMIPS源代码、测试程序。(It provides the OpenMIPS source code and test program in each chapter, which is written in the book "do it yourself CPU".)

说明：  基于FPGA的串口发送和接收，使用的verlilog语言(Using Verilog serial port program, send and receive.)

verilog 或门程序 初学者必备。。。。。。。。。。。。(verilog )

本源代码是RS（31,19）编码器的顶端实现程序和测试程序，此程序可以验证编码器工作与否。此代码，已在ModelSim验证通过。并附上测试时所产生的结果图像。(Source code is RS (31,19) encoder to achieve the top programs and testing procedures, this program can verify the encoder to work or not. This code has been verified in ModelSim. Together with the result when the test images.)

MP3解码器的VHDL源代码 ,很实用的，设计时可以参考 ，很罕见的完整MP3 decoder源码 -VHDL code for MP3 decoder

VHDL产生时钟50分频程序，供初学者参考-VHDL generated clock frequency of 50 procedures, the reference for beginners

实现千兆以太网数据发送，通过GMII接口向PHY写数据，控制PHY发送数据。(Implementation of Gigabit Ethernet data transmission, write data to the PHY through the GMII interface, control PHY data.)

pid程序,新学者，使用FPGA学习，希望大家一起学习

这是我准备电子设计大赛时，用VHDL写的一个自动打铃系统，很好的学习资料。-This is when I am going to Electronic Design Contest, use VHDL to write an automatic bell playing system, a very good learning materials.
