Digital Design and Modeling with VHDL and Synthesis

A simple Manchester Encoder to convert serial data to Manchester encoded data.

说明：  插值滤波器,用于音频解码调制解调,滤波器系数用移位相加实现(Interpolation filter, audio decoder for modulation and demodulation, filter coefficient shift combined with the realization of)

项目目的是设计 DCT 和 IDCT 在 VHDL 中。离散余弦变换图像压缩中用于压缩的 JPEG 图像。此文件包含 DCT 和 IDCT 块和顶级模块于一体的两个块和矢量来测试这两个模块。

改自特权同学verilog语言写sdram测试程序；支持256M内存(verilog sdram )

图像采集 VGA输出 图像的边缘 ov7670(V image acquisition VGA output image edge)

说明：  是基于apb总线下的timer外设的rtl代码，主要包括apb_timer的master逻辑verilog，以及相应的开发文档，包括寄存器的描述，功能特性等。(RTL code is based on timer peripheral under APB bus, which mainly includes master logic Verilog of apb_timer and corresponding development documents, including the description of registers, functional characteristics and so on.)

说明：  实现数字频率合成实验，加载数据ram,形成波形(The experiment of digital frequency synthesis is realized, and the data RAM is loaded to form the waveform)

ARM7 VERILOG源码，非常精简，3级流水线(ARM7 VERILOG source code, very streamlined, 3-stage pipeline)

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.)

我用verilog hdl写的tft lcd屏的控制程序，用来点亮屏上的任意点-I write the program in verilog hdl,it is used to control the tft lcd
