这是个UART发送的VHDL程序，调试过，还可以

xilinx的时序约束实验，通过阅读本文档，你可以用全局时序约束来轻松提高已有的项目的系统时钟频率，同时你还可以用映射后静态时序报告以及布局布线后静态时序报告来分析你的设计性能(Xilinx timing constraints of the experiment, by reading this document, you can use the overall timing constraints to easily enhance existing projects the system clock frequency, at the same time you can also use static timing report after mapping, as well as after placement and routing static timing analysis report to you design performance)

MD5 算法在Xilinx FPGA上的实现，希望对大家有用。(MD5 algorithm in Xilinx FPGA Implementation, in the hope that useful to everyone.)

说明：  16位右移位寄存器 下面描述的是一个位宽为16位的右移位寄存器，实际具有环形移位的功能，是在右移位寄存器的基础上将最低位的输出端接到最高位的输入端构成的。其功能为当时钟上升沿到达时，输入信号的最低位移位到最高位，其余各位依次向右移动一位。(16-bit right shift register The following description is a right shift register with a bit width of 16 bits. It actually has the function of circular shift. It is based on the right shift register, which connects the lowest bit output terminal to the highest bit input terminal. Its function is that when the rising edge of the clock arrives, the lowest displacement of the input signal reaches the highest position, and the rest of you move one bit to the right in turn.)

利用FPGA采集按键，加了消斗。其实跟单片机的效果差不多。-The use of FPGA collect keys, plus the elimination fighting. In fact, almost with the effect of SCM.

实现基于FPGA的控制MCP2515发送的程序，本人编写通过测试，希望提供帮助(FPGA-based control program sent MCP2515, I write to pass the test, hoping to help)
