8位大小比较器的VHDL源代码，Magnitude Comparator VHDL description of a 4-bit magnitude comparator with expansion inputs-eight compared with the size of the VHDL source code, Magnitude Comparator VHDL description of a 4-bit magnitude comparator inputs with expansion

pc104接口的verilog代码，仅供参考-pc104 verilog interface code for reference purposes only

说明：  基于BP算法的LDPC译码程序，采用vhdl语言，bp算法(BP algorithm based on LDPC decoding program using vhdl language, bp algorithm)

FIFO的VERILOG代码编写 可综合的Verilog FIFO存储器(The VERILOG code FIFO write comprehensive Verilog FIFO memory)

本代码是实现VGA的显示的，在quartus开发环境下能完整的实现VGA的彩色显示，彩色条纹，通过不同按键来实现不同的效果，对于初学者有很大的帮助。

并串转换模块，内含有另个.vhd文件。一个是自己写的比较简单 另一个是参考的。-And the string conversion module, which contains another one. Vhd file. One is its relatively simple to write the other is the reference.
