8051内核的hdl代码，实际上是verilog格式不过上载页面只有一个vhdl选择，值得一读， 里面对仿真和验证的说明很有含金量...

用Verilog语言编写的对m序列进行汉明码编译码的程序。具体实现为产生m序列后对其进行(7,4)汉明码编码并加错，然后将其纠错译码并输出，详细过程见仿真。(Written by Verilog m sequence of procedures for coding and decoding Hamming codes. Concrete realization of m sequence to produce its (7,4) hamming code and a mistake, and then error correction decoding and output, see the detailed process simulation.)

IIC slave controller source code

This an interpolating by 2 half-band filter with 79 taps (40 none-zero coefficients).

用verilog写的简单的CPU，有详细注释(Use verilog to write a simple CPU, with detailed notes)

This is code of UVM CALLBACK function.

VERILOG实现无分频时钟，包括测试文件，经过验证可用(VERILOG is no difference between the frequency of the clock implementation, including test papers, can be used after authentication)

说明：  ds1302时钟驱动程序，已在quartus上验证可以是直接使用(DS1302 clock driver, which has been verified on quartus, can be used directly)

用vhdl实现双向移位寄存器 仿真环境MAXPLUS-II，QUARTUS--bidirectional use VHDL simulation environment shift register Segments-II, QUARTUS-

说明：  关于usb调试相关测试 代码，用于测试和适配等(usb coding for testing , verigy, for studing usb and fpga)

用VHDL制作的I2C控制器，是一个component,之间添加就可以使用。-VHDL produced using I2C controller, is a component, you can use to add between.
