用VHDL语言实现的ARM处理器的标准内核的源代码程序，可在重用-use of the VHDL standard ARM processor core source code procedures, the reuse

说明：  用VHDL语言实现电子钟(Using VHDL language electronic bell)

说明：  一个PN序列发生器，大M序列，供参考学习，(A PN sequence generator, the M series, for reference study,)

载波同步，costas环，基于Verilog的载波同步环(Carrier synchronization, costas ring, based on Verilog carrier synchronization ring )

用Verilog 实现的电子时钟，给初学者一个模版，学习Verilog。-Using Verilog realize an electronic clock, a template for beginners to learn Verilog.

在quaritusII的开发环境下，verilog语言编写的m序列发生器代码，这种算法简短而有效，非常实用。(In quaritusII development environment, verilog language of m sequence generator code, this algorithm brief but effective, very practical.)

说明：  verilog标准语法，还有很多的样例参考，学习的好资料。(Verilog standard grammar, there are many examples for reference, good learning materials.)

设计制作一个检测4*4矩阵键盘的按键编码的实验，把实际按键的键值的八位编码先转换成从0000—1111的编码，再译成数码管能识别的八位编码，在数码管动态显示时，4*4矩阵键盘的第一行对应00—03，第二行对应04—07，第三行08—11，第四行对应12—15。(Design a 4* 4 matrix keyboard key coding experiments to detect the key the actual key octet coded first convert from 0000-1111 encoding, and then translated into digital tube to identify the eight coding, digital tube dynamic display, the first line of the 4* 4 matrix keyboard corresponding to 00-03, the second line corresponds to 04-07, the third line of 08-11, the fourth line corresponds to 12-15.)
