vhdl描述的显示代码 maxplus2开发环境

dpim是光通信中使用的一种调制方式，这里提供的是它的环回代码，自己可以根据需要拆开了下载到两块板子上。(dpim is used in an optical modulation, here is its loop-back code, they can download needed two apart on the board.)

串口模块程序，可以实现串行发送和接收功能，比特率可以不断调整，数据的长度是可以改变的-Serial port module program, you can achieve the serial send and receive functions, and bit rate can be continuously adjusted, the data length can be changed

说明：  一个8位RiSC单片机的VHDL代码， 具有很好的参考价值。(an eight RiSC SCM VHDL code, is a good reference value.)

1 由matlab计算FIR数字滤波器的滤波系数； 2 用VHDL语言设计逻辑电路，再通过QUARTUS II 软件，将各个模块的电路封装成期间，在顶层设计中通过连线，完成整个系统。 (matlab VHDL QUARTUS )

说明：  FPGA对系统50M时钟进行分频。FPGA最基本功能基础(FPGA Verilog program, key detection, program jitter elimination, jitter elimination, delay detection keys)

假设每个从设备中有可访问APB寄存器16个，位宽均为32比特，16个寄存器的访问地址计算方式为 基址 +　寄存器编号左移２位（byte 偏移）(Assuming that there are 16 accessible APB registers in each slave device, the bit width is 32 bits, and the access address of 16 registers is calculated by base address + register number left shift 2 bits (byte offset).)

介绍了ＶＨＤＬ编程语言的基本语法，和一些编程实例-VHDL programming language introduced the basic grammar, and some programming examples

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.)
