Toplevel VHDL Structural model of a system containing 8051

用VHDL编写的计算器，能实现简单的加减乘除四则运算

自己写的位同步实验程序参考，该算法需要发送和接收方的频率比较稳定时，可以很快地达到位同步，且十分稳定。位同步是通信技术的基础之一，希望对大家学习有所帮助。(The program is a reference used for bitsynchro writed by myself.When the both send s and receive s frequency are stable,the program can reach bitsynchro fastly.)

USB口的设计，包括驱动程序的设计，以及软件的安装演示，软件的介绍，以及工作模式-USB port design, including the driver design, and installation of software, presentation, software presentation, and working models

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

两个例子提醒我们如果我们要使用锁存器则不需要任何操作，如果我们想避免锁存器的话，我们要让这个元器件的每一个可能条件赋予一个值-signal or variable "" may not be assigned a new value in every possible path through the Process Statement
