2位并行加法器初学者必看初步了解FPGA

VHDL之二進制轉BCD碼之程式碼，算完整的(Of binary to BCD code VHDL code, operator complete)

说明：  基於空間向量調變的開關法，在於載波做比較切出方波再送至開關讓馬達啟動(Based on the switching method of space vector modulation, the square wave is cut out for carrier comparison and sent to the switch to start the moto)

说明：  HDB3编码Quartus2 10.0的工程，modelsim仿真，有实物图、仿真图以及源程序，适合做通信原理课程设计的同学参考使用(HDB3 encoding Quartus2 10.0 project, modelsim simulation, there are physical map, simulation diagrams and source code, suitable for students of communication theory courses designed for reference use)

说明：  使用FPGA实现RGB图像转灰度图像的算法，下载入自己的电路板可直接将摄像头拍摄到的图像实时转换成灰度图像(FPGA is used to realize the algorithm of transforming RGB image into gray image. The image captured by the camera can be converted into gray image in real time by downloading it into its own circuit board)

verilog hdl 编写的64点fft代码，适合很多芯片(coded by verilog hdl that implement 64 point fft, suite to many core)

用VHDL语言将二进制数据转换成十进制数据，并将十进制的每一个位分离出来单独存放。使用状态机实现，程序简单，仿真效果很理想，占用可编程器件的资源较少。-VHDL language with the binary data into decimal data and decimal places separated from each store individually. Realize the use of state machine, the program is simple, simulation results are satisfactory, occupation of programmable devices have fewer resources.

ssb的调制与解调，包括信号的产生、乘法器、加噪、BPF、解调等部分。(ssb modulation and demodulation, signal generation, multiplier, adding noise, BPF, demodulation section.)

上海外滩看到的最大的LED显示屏的内核源代码，主要是完成视频信号的远距离传输的编解码与接口转换-Shanghai Bund to see the largest LED display in the kernel source code, mainly to complete the long-distance video signal transmission codec conversion and interface

4位ALU,有两个4位输入，4位输出实现逻辑运算和算术运算，逻辑与或非，加1，减1等等功能(4 ALU, logical and arithmetic operations)
