Verilog编写的串口通讯下解码状态机(Verilog serial communication prepared under the decoder state machine)

利用FPGA内核产生SPWM波，并且频率可调(The FPGA kernel is used to generate SPWM waves, and the frequency is adjustable)

该书介绍了英特尔的80x86CPU和一些串行通信芯片，以及汇编语言。(The book introduces the Intel 80x86CPU and some serial communications chip, and assembly language.)

利用基本全加器的逻辑表达式，写单个加法器模块。 通过模块例化，直接级联加法器，同时在输入输出端口加入寄存器。 最后可以实现不考虑进位的加法。

Frame Control field
Retry:
Set in case of retransmission frame
More fragments:
Set when frame is followed by other fragment
Power Management
bit set when station go Power Save mode (PS)
More Data:
When set means that AP have more buffered data for a station in Power Save mode

64点的 FFT verilog,它是串行计算的，工作频率不到100M，计算速率很高，里面的层次很清晰。(64-point FFT verilog serial computing, the operating frequency of less than 100M, the calculated rate is high, the level inside is very clear.)
