LDPC编译码

LDPC码不同码率对比，1/2与1/3码率对比。码长512.迭代次数50次。(Comparison of different rate of the LDPC code, 1/2 compared with the 1/3 code rate. 512 yards long. 50 times the number of iterations.)

代码属于原创，写了一天，比网传的简单明了；用Verilog语言实现的IIC通信协议，用分频计数器的方法实现SCL的输出，同样用计数器的方式确定SCL的低电平中点，在此改变SDA的值。

fpga正弦波发生函数，可用于自动生成rom文件(fpga sine wave generating function)

在FPGA内部实现数据大小排序是一件非常困难的事情，本例中以流水线方式实现16个数据的排序！

交通灯控制系统VHDL源码，用VHDL语言、MAXPLUS2环境设计实现(VHDL core)

简单的单周期CPU设计，实现的指令有：算术运算指令、逻辑运算指令、移位指令、比较指令、存储器读/写指令、分支指令、跳转指令、停机指令。(Simple single-cycle CPU design,The instructions implemented are as follows:Arithmetic operation instruction, logical operation instruction, shift instruction, comparison instruction, memory read/write instruction, branch instruction, jump instruction, stop instruction.)

本源码是用Verilog编写的12位移位相加乘法器的设计源码，开发软件为MAX+PLUS，已经测试通过。(The Verilog source code is written in the sum of 12-bit shift multiplier design source code, developing software for the MAX+ PLUS, has been tested.)
