通用功能封装，如打印，字符串处理，网络连接等

Xilinx虚拟连接，这是一种基于TCP/IP协议的通信技术，以实现JTAG功能，通过这样的连接，可以访问开发的FPGA或者SOC，而不需要通过传统的JTAG电缆。(Xilinx Virtual Cable (XVC) is a TCP/IP-based communication protocol that acts like a JTAG cable and provides a means to access and debug your FPGA or SoC design without using a physical cable. In this document are the general details of this XVC 1.0 protocol.)

DES - Cryptograther using c#

定义一个基类MyGraph，要求有一个纯虚函数double Area()=0。从基类派生一个圆类Circle和矩形类Rectangle，再由Rectangle类派生出Square类，分别给出Area()实现。 重载“>>”，实现对图形信息的输入。在主函数中计算三种形状的面积，并显示输出。 (Define a base class MyGraph, requires a pure virtual function double Area () = 0. Derive a circle and a rectangle class Rectangle Circle class from the base class, and then by Square Rectangle class derived class, are given Area () implementation. Reload " > > " to achieve the input of graphical information. Calculate the shape of the three main functions in the area, and display output.)
