本代码实现了486总线的功能，初学者可以借鉴学习

VHDL，verilog串并转换源程序 Xilinx公司参考资料-VHDL, verilog Series and conversion company Xilinx reference source

FFT with fix point 2*N

高速多通道crc实现，可以并行实现5个通道数据的校验，支持10GB以太网标准-High-speed multi-channel crc implementation, can be achieved in parallel 5-channel data validation, support for 10GB Ethernet standard

4选1数据选择器，有使能端控制，4个数据输入，2个地址端，1个输出(4 1 data selector, enable end control, four data inputs, two addresses end, an output)

使用Altera公司的FPGA进行VHDL开发。使用quartus2 9.0软件在EP1C3T144C8开发板上实现对4x4键盘的输入控制，并显示在一个8段式数码管上。(The use of Altera' s FPGA-VHDL development. Use quartus2 9.0 software EP1C3T144C8 the development board to realize 4x4 keyboard input control, and displayed in an eight-stage digital pipe.)

用FPGA 是先键盘的程序，is good for you -FPGA is the first keyboard to use the procedure, is good for you

FPGA中嵌入8051的核 并且实现控制128*64的液晶显示-FPGA embedded in 8051 and to achieve control of the nuclear 128* 64 LCD

产生高斯最小相移键控信号的阐述仿真，包括调制解调、信道模型等。(Simulation program to realize GMSK transmission system)

说明：  在FPGA内利用verilog实现数字上变频(apply the verilog to implement the digital up frequency)

我的学习经验，一种自适应分频及分频方法的实现，很好用的哦-my learning experience, an adaptive frequency-frequency method and the realization of the good, oh
