GIF图像查看器的VHDL代码

说明：  DDS的基本原理主要由五部分组成，分别是；相位累加器，正弦波形存储器，数模转换器，低通滤波器和时钟，将相位累加器输出的数据作为地址，用来查询表的数据，将取出的正弦数据通过数模转换器输出模拟信号，模拟信号再通过一个低通滤波器输出纯净的正弦波信号。(The basic principle of DDS is mainly composed of five parts: phase accumulator, sinusoidal waveform memory, digital to analog converter, low-pass filter and clock. The output data of phase accumulator is used as address to query the data of table. The extracted sinusoidal data is output analog signal through digital analog converter, and the analog signal is output pure sine through a low-pass filter Wave signal.)

this contain the source code for noise cancellation ,which can be used in c platform.

说明：  介绍了Displayport规格中lind training的背景研究，设计和实现。(As the requirement for bandwidth continues to increase in the video market, retaining the signal integrity becomes increasingly more difficult. For many of todays commonly used video interfaces, there are devices that can be used to assist in this matter. However, the use of such a device is only partially documented in the DisplayPort specification for the receiving image device, which means that the receiving side of the video link is free to choose its own implementation. This report presents, together with background research and design decisions, a suggestion for such an implementation. This implementation would need to be compatible towards a wide range of possible video Source devices and DisplayPort cables.)

说明：  I2C完整代码，可综合，可仿真，已经过验证(I2C code can been syn and simulation ,veritify)

改写四号中断的 自己编的，，，，，，求过啊！！！一个很简单的小程序(Rewrite the fourth interruption of their series,,,,,, begged ah! ! ! A very simple little program)

高速计算机旋转坐标算法的硬件实现，用于快速傅里叶算法的核心单元-Rotating coordinates high-speed computer hardware algorithm for fast Fourier algorithm is the core unit

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).)

FFT vhdl generic: I m new to vhdl, and I tried to use xilinx fft core, but when I try to simulate it in test bench using ise simulator, I get zero results. here is what I do: 1- from core generator I choose fft core and create .vhd & .vho & .xco files. 2- I add the .xco & .vhd files to my project. 3- I create a new vhdl source as a wrapper to the core and add the code from the .vho files where it exactly says, and take the ports of the component and add it to the entity of the wrapper file.-FFT vhdl generic: I m new to vhdl, and I tried to use xilinx fft core, but when I try to simulate it in test bench using ise simulator, I get zero results. here is what I do: 1- from core generator I choose fft core and create .vhd & .vho & .xco files. 2- I add the .xco & .vhd files to my project. 3- I create a new vhdl source as a wrapper to the core and add the code from the .vho files where it exactly says, and take the ports of the component and add it to the entity o
