全部通过，是我的精心设计，完全满足初学者的要求。

A programming language that can decode alpha numeric

用VHDL实现串口 可以实现与pc机的通信 收发 中断都可以 效果比较好-VHDL implement serial port, it can communicate with pc, it can accept and send message, and it can be interrupted.

本源码为Nios II的开发示例,主要演示Nios II的定时中断器的应用。开发环境QuartusII。 本示例十分经典，对基于SOPC开发的FPGA初学者有很大帮助。-The source code for the Nios II development of an example, the main demonstration Nios II interrupt timing device applications. Development environment QuartusII. This example is very classic, FPGA-based SOPC development of great help for beginners.

说明：  基于quartus2的jk触发器设计，内含源码和仿真图(Jk flip-flop design based on the quartus2, containing source code and simulation diagram)

该计数器可以实现从0到1000的技术，程序简练执行效率高(counter1000)

关于FPGA的书籍，介绍了大量的Verilog实例，对初学者很有帮助-Books on the FPGA, introduced a large number of Verilog examples very helpful for beginners
