通信系统中数据的传输以帧为单位，在FPGA中帧头检测是通信系统中的一部分，该程序实现了FPGA中帧头的检测。(Transmission of data in a communication system in units of frames, the frame header is detected in the FPGA part of the communication system, the realization of the frame header is detected in the FPGA.)

这个程序是 用于两个浮点数字加法器使用 VHDL 语言。

The program is used to establish communication with the pc through serial port. It utilses the inbuilt micro controller called as picoblaze for the processing for implementation on spartan 3E

等精度数字频率计 的一个工程---包括vhdl源程序和编译后产生的相关文件-Such as precision digital frequency of a project- including VHDL source code and compile the relevant documents after

用Verilog实现的交通信号灯控制，主干道和支路通行的时间不相等(Using Verilog implementation of traffic signal control, the trunk road and the slip is not the same passage of time)

说明：  8位大小比较器的VHDL源代码，Magnitude Comparator VHDL description of a 4-bit magnitude comparator with expansion inputs(eight compared with the size of the VHDL source code, Magnitude Comparator VHDL description of a 4-bit magnitude comparator inputs with expansion)

说明：  QPSK的解调程序，采用Verilog编写而成(QPSK demodulation program, written by Verilog)
