很好的quartus软件仿真教程，flash版。

design cpu 16 bits by verilog HDL.

FPGA YCbCr444转YCbCr422实验 很好的参考(FPGA EP4CE40F23C6 YCbCr444 turn YCbCr422 experiment)

基于sopc ep2c5开发板的液晶字符显示例程-Sopc ep2c5 development board based on liquid crystal character display routine

这是“状态机设计（讲稿）”，希望对正在学VHDL的同学有帮助，谢谢！-This is the "state machine design (the script)", and I hope to learn VHDL is there to help the students, thank you!

这是rs（255，223）编码的verilog源程序。里面有：encode、decode、test－bench等文件。(This is rs (255,223) verilog source coding. Inside : encode, decode, test-bench and other documents.)

4 bit convoltion with vhdl.

-- Booth Multiplier -- This file contains all the entity-architectures for a complete -- k-bit x k-bit Booth multiplier. -- the design makes use of the new shift operators available in the VHDL-93 std -- this design passes the Synplify synthesis check -- download from: www.fpga.com.cn & www.pld.com.cn--- Booth Multiplier-- This file contains a ll the entity-architectures for a complete-- k- bit x k-bit Booth multiplier.-- the design mak es use of the new shift operators available in th e VHDL-93 std-- this design passes the Synplify synthesis check-- download from : www.fpga.com.cn

使用QuartusII软件，利用VHDL语言设计实现CPU,其中包含时序图仿真。(Using software QuartusII, using VHDL language to design the CPU, which contains sequence diagram simulation.)

说明：  FPGA 学习实例 动态时钟、面积、速度优化相关代码(Codes related to dynamic clock, area and speed optimization for learning examples of FPGA)

4-16译码器，用VHDL编写的，可以直接下载到可编程逻辑器件中(4-16 decoder, written with VHDL, can be directly downloaded to the programmable logic device)
