异步FIFO的设计 包括testbench 已调试成功

在quartusII环境下采用对编解码芯片HD6408和HD6409驱动的方式实现曼彻斯特编解码(Environment in quartusII codec chip used on the HD6408 and HD6409-driven way to achieve encoding and decoding of Manchester)

载波同步的verilog代码，是新手学习同步的最佳选择，值得推荐。(Verilog code carrier synchronization, synchronization is the best choice for novices to learn, it is worth recommending.)

This code for countor . it is design in verilog HDL.

The code is used to interface PC monitor with Spartan 3E for the display. if you run the program on spartan 3 you would be able to see different test pattern on the monitor screen
