实现PWM波型....使用VHDL语言

伪随机序列发生器的vhdl算法 设计一个伪随机序列发生器，采用的生成多项式为1+X^3+X^7。要求具有一个RESET端和两个控制端来调整寄存器初值（程序中设定好四种非零初值可选）(m sequence vhdl)

说明：  fpga串口的接收程序基于verilog语言拿走不用谢。(The receiving program of FPGA serial port is based on Verilog language.)

此为数学形态滤波器消燥的代码，用于一维信号，涉及一个具体的例子，需要的话可以自己修改，修改相应的结构元素。(This is a mathematical morphology filter away dry code, used to one dimensional signal, involving a concrete example, necessary can change ourselves, change the structure of the corresponding elements)
