并行通信代码（调试通过）

用Verilog编写的基于FPGA的按键边缘检测技术，通过此模块可以很好的消除在按键过程中因抖动或误按造成的 麻烦，同时，在边缘检测技术中使用了约翰逊计数器的思想，是的代码简介，思路清晰。源码中含有大量的注释，有助于读者更好地了解编码思想。

密码锁verilog源代码，包括四个七段数码管显示模块，设置密码以及输入密码校验模块(Password lock Verilog source code, including four of seven digital tube display module, set the password and password verification module)

实现自然对数运算的cordic算法的matlab浮点仿真，以及针对FPGA硬件平台的定点仿真测试(Achieve natural logarithm of cordic algorithm matlab floating point emulation, and FPGA hardware platform for fixed-point simulation testing)

VHDL examples for 16x16 times, if need detail pls let me know

数字滤波器包含IIR数字滤波器和FIR数字滤波器。本设计的工作主要是Labview软件部分，包括信号生成模块、滤波模块、显示模块的设计(IIR digital filter comprises a digital filter and FIR digital filters. The design work is mainly Labview software parts, including signal generation module, filter module, display module design)

针对32位MIPS微处理器中CLZ指令（对单个字高位连零进行计数）的实现电路，使用了类似于超前进位的逻辑结构。包含测试文档，以及Design Compile所用的环境和脚本。(The CLZ instruction counts the number of leading zeros in a word. The 32-bit word in the GPR rs is scanned from most-significant to least-significant bit.The number of leading zeros is counted and the result is written to the GPR rd. If all 32 bits are cleared in the GPR rs, the result written to the GPR rd is 32. )

本设计是一个伪随机数发生器。此设计；
