VHDL开发的计数器。源程序不复杂，应该都能看懂。最重要的注意：是时序问题

自己编写的红外解码子程序，但CPU资源占用较高，作教学示范用途。(prepared their infrared decoding routines, but higher occupancy CPU resources for teaching demonstration purposes.)

在quartus平台下使用verilog语言编程实现简单的单流水线CPU，可以执行16条基本指令(Quartus platform in the verilog language programming using a simple single-line CPU, can perform 16 basic instructions)

saber的仿真模型，是一个电源的，经过调试已经成功(The simulation model of the saber, is a power, after commissioning has been successfully)

使用VHDL编写数字蜂鸣器音乐，整个项目文件，可直接使用 (Use VHDL to write 1602led driver, the entire project file, and can be used directly.)

说明：  lab report for lab 4

this project is based on 2*1 and 4*1 multiplexer and 1*2 and 1*4 demultiplexer using vhdl.this is the 100 correct code,reference is taken from book digital electrionics written by anand kumar.please use quatrus to access this code.this code can be used for the final year project for engineering. Here dataflow techniques and behavioural
