Verilog HDL程序LDPC编码器

说明：  fpga的hdmi驱动，只包括视频信号没使用音频线，总体跟DVI控制一样，可参考DVI说明手册进行观看(driver of HDMI using fpga)

MIPS 处理器程序，出自于《CMOS VLSI Design and Systems Perspective》书中。可以实现LB、SB、RTYPE、BEQ、J指令，仿真测试可以用。

FIR滤波器的VHDL源代码及测试文件，已通过编译仿真，绝对正确。(FIR filter VHDL source code and test files, has passed the compiled simulation, absolutely correct.)

说明：  这是一个带声音的弹球小游戏，通过VGA口显示，通过扩展口JA的 pin4和 pin GND输出声音， BTN3 BTN2 控制挡板左右移动，弹球和挡板都自带动画效果(This is a band sound pinball game, through the VGA port shows that through the expansion of the mouth of the JA and pin4 output pin GND voice, BTN3 BTN2 control baffle around Mobile, pinball and baffle all bring their own animation effects)

矩阵键盘控制的FPGA，verilog语言实现，包括rtl，ucf,以及testbench的详尽代码(Exhaustive code matrix keyboard control FPGA, Verilog language, including the rtl, ucf, and testbench)

relative cpu design implementation

说明：  基于CycloneV FPGA与电阻网络的数模转换器代码，能够实现键控更改频率，通过ROM IP核存储波形数据。(Digital to analog converter code based on cyclonev FPGA and resistance network can realize keying change frequency and store waveform data through ROM IP core.)

良好的Coding Style能减少Bug，减少锁存器出现的可能以及其他隐藏逻辑错误，也有助于减小芯片面积或所用资源(Good Coding Style can reduce Bug, reduce the possibility of latches and other hidden logic errors, and also help to reduce chip area or resources used.)

说明：  verilog编码器、计数器、加法器的程序(Verilog encoder, counter, adder procedures)
