JOP字节码获取的源码，很重要，具体FPGA中实现

本模块的功能是验证实现和PC机进行基本的串口通信的功能。需要在PC机上安装一个串口调试工具来验证程序的功能。程序实现了一个收发一帧10个bit（即无奇偶校验位）的串口控 //制器，10个bit是1位起始位，8个数据位，1个结束 //位。串口的波特律由程序中定义的div_par参数决定，更改该参数可以实 //现相应的波特率。程序当前设定的div_par 的值是0x145，对应的波特率是 //9600。用一个8倍波特率的时钟将发送或接受每一位bit的周期时间 //划分为8个时隙以使通信同步. //程序的工作过程是：串口处于全双工工作状态，按动key1，FPGA向PC发送“21 EDA" //字符串（串口调试工具设成按ASCII码接受方式）；PC可随时向FPGA发送0-F的十六进制 //数据，FPGA接受后显示在7段数码管上。 //视频教程适合我们21EDA电子的所有学习板(this is a base vhdl for uart progarm.)

说明：  采用FPGA（现场可编程门序列）编写VHDL语言设计多路同步脉冲发生器，对信号进行分频处理，实现四路信号相位相差T/16和T/8的延迟相位输出，实现的四路脉冲与传统的脉冲同步器不同，它具有高集成度，高通用性，容易调整和高可靠性等特点。(Using FPGA (field programmable gate sequence) to write VHDL language to design multi-channel synchronous pulse generator, to divide the frequency of the signal, to achieve the four-way signal phase difference T / 16 and T / 8 delay phase output, the realization of the four-way pulse is different from the traditional pulse synchronizer, it has the characteristics of high integration, high-throughput, easy adjustment and high reliability.)
