vhdl code for programming

代码是一个复数乘法器，两个复数相乘，只用到了2个实数相乘，运算量少(Code is a complex multiplier, two complex multiplication, uses only real number multiplied by 2, operations less)

这是脉冲宽度调制技术的VHDL代码，包括一个比较器，正弦波发生器，锯齿波发生器，脉冲宽度调制器等。

用verilog语言写的串口通信程序,包括收发两个模块,可用于FPGA的通信中,可通过程序设置收发的位数,有很好的扩展性.-Verilog language used to write serial communication program, including the sending and receiving two modules can be used for FPGA communications, you can send and receive through the program to set the number of bits, there is a very good scalability.
