verilog 写的 “梁祝”乐曲演奏电路

MCP4725实现的i2c驱动程序，通过DA转换实现函数发生器(MCP4725 come ture i2c drive program,Through da conversion function generator in English)

说明：  stepper motor module on spartan 6 and 24MHz clock fequency

一个8位的CPU设计，用verilog语言写的，希望有用(A CPU OF 8 BITS )

模拟示波器的现实程序，有x，y和光标。采用AD5440输出，现实效果很好。（示波器x-y方式）(Analog oscilloscope reality program, there are x, y and cursor. Using AD5440 output, real good results. (Xy oscilloscope mode))

FFT的VHDL源代码-fft vhdl source code

基于FPGA编写一个时间显示，计数功能，年月显示的程序，(FPGA-based preparation of a time display, counting, years show program,)

decoder 2-4 digital core

此vhdl程序实现了在FPGA上构建UART通信串口。分为两部分，UART的发送端transfer和接收端receiver。需要外部根据需求提供波特率时钟。(This program implements the building vhdl UART serial interface on the FPGA. Divided into two parts, UART transfer sender and receiver receiver. Required to provide the baud clock external demand.)

由Verilog编写在FPGA实现sobel算法应用于图像边缘检测，工程文件可在quartus13.1以上版本打开；工程使用到ram、fifo、pll三种ip核，design文件夹下包含ram、fifo、vga控制以及串口收发和sobel算法模块，sim和doc文件夹下分别包含modelsim的仿真模块和仿真结果；测试时将200*200分辨率的图片用matlab文件夹下的matlab脚本压缩、二值化，再将生成文件中数据用串口发给FPGA，边缘检测结果会通过VGA输出。(Written by Verilog in the FPGA implementation sobel algorithm applied to the edge detection of the image, the project file can be opened in the quartus13.1 or later project use ram, fifo, pll three ip kernel, design folder contains ram, fifo, vga control and Serial port transceiver and sobel algorithm module, sim and doc folder, respectively, include modelsim simulation module and simulation results test will be 200* 200 resolution picture matlab folder under the matlab script compression, binarization, and then generated Data in the file with the serial port to the FPGA, edge detection results will be output through the VGA.)

提供了利用 GPIF 对 FX2LP 与同步 FIFO CY7C4625-15AC 之间的接口进行设计的源代码(Provides for the use of GPIF FX2LP and synchronization FIFO CY7C4625-15AC to design the interface between the source code)
