xilinx CTC IPcore(encoder 和 decoder）的标准测试，未经信道加噪

说明：  内有一PCI 主 和PCI从，PCI TARGET 都是公开代码的，是工程文件，有仿真工程，使用说明。觉得好的就推荐一下。 本PCI_HOST目前支持： 1、 对目标PCI_T进行配置； 2、 对目标进行单周期读写； 3、 可以工作在33MHZ和66MHZ 4、 支持目标跟不上时插入最长10时钟的等待。 ALTERA的PCI竟然收费的！！！软件里面调试仿真了半天，终于调通了，到了下载就突然弹出窗口说包含了有限制的IP CORE，是限制使用的(There is a PCI from PCI proprietors, PCI TARGET is open source, is the project document, there is simulation project, for use. Feel good about the recommendation. The PCI_HOST currently supports: 1, on the target configuration PCI_T 2, on the target for single-cycle read and write 3, can work in the 33Mhz and 66MHZ 4, to support the goals behind to insert a maximum of 10 clock hours of waiting. ALTERA the PCI even charges! ! ! Inside simulation software debugging for a long time, and finally had transferred to the download on the sudden pop-up window that contains a limited IP CORE, is to restrict the use of)

基于QuartusII环境下以模块化的形式做成的视频复合同步信号。-QuartusII-based environment to create the form of modular composite video sync signal.

本程序利用VHDL实现二维离散余弦变换，经本人测试，在Quartus II7.0软件上可正确仿真，希望大家积极采纳

用verilog编写在FLEX10K上实现的简易CPU-used in the preparation of Verilog FLEX10K achieve simple CPU

说明：  内部含3个模块，使用DDS产生200k与500k的正弦波，两者相加后过数字低通滤波（通带0-200k，阻带400k以上），并将波形输出，实测FFT分析中看不到500k分量。其中数字滤波器采用MATLAB设计（FIR+等波纹，阻带衰减-80dB）(There are three modules in the system. DDS is used to generate 200K and 500K sine waves. After adding the two modules, the digital low-pass filter (passband 0-200k, stopband above 400k) is used, and the waveform is output. 500K component can not be seen in the actual FFT analysis. The digital filter is designed by MATLAB (FIR + equal ripple, stopband attenuation - 80dB))
