跑马灯程序FPGA

十分基础的CCD的测试程序，大家可以下载调试CCD(this is a ccd test chengxu ,it is very good to use ,you can down it )

该程序是整个OFDM接收机的程序，希望对做这方面的朋友用些帮助，也希望朋友们和我一起探讨OFDM收发信机。(The program is the whole OFDM receiver process, hope to do in this area with some friends to help and also hope that friends and I explore OFDM transceiver.)

mimo检测算法的FPGA实现，包括最小迫零检测算法和ML检测算法，已在ISE上仿真通过 (mimo detection algorithm for FPGA implementation, including the smallest zero forcing detection algorithm and ML detection algorithm has been simulated by ISE on)

VHDL实例这是我下载到的最好的VHDL实例，看完这些实例，可以使你有一个长足的进展-VHDL example

内容有VHDL语法总结及相应的实例应用，每个程序我都亲自试过，特别适合初学VHDL的同学们。常用的程序有 设计一个M序列发生器，M序列为“11110101”、 设计一个彩灯控制器，彩灯共有16个，每次顺序点亮相邻的四个彩灯，如此循环执行，循环的方向可以控制。设计一个跑马灯控制器。一共有8个彩灯，编号为LED0~LED7，点亮方式为：先从左往右顺序点亮，然后从右往左，如此循环往复等等。这些都是我在考试前熬夜总结的，很有用。如果配合开发板用的话，那就更好了 ( VHDL syntax summary content and the appropriate application instance, every program I have personally tried, especially for students of beginner VHDL. Common program has designed a sequence generator M, the M series is 11110101 , a lantern controller design, a total of 16 lights, each sequence of four adjacent lights lit, so the cycle execution cycle direction can be controlled. Marquee design a controller. A total of eight lights, numbered LED0 ~ LED7, the lighting way: first left to right order of light, and then right to left, so the cycle and so on. These are all I stay up all night before the exam summary, very useful. When combined with the development board, then so much the better )

encoding and decoding of audio signal

1对于按键输入，请加入语音输出电路，代表按键sw1反馈的音频信息。每次按下sw1按钮时，它们都会发出0.1秒1KHz的声音。

实验用16位全加器的VHDL代码，适合初学者学习，数电学习的好工具。 (Experiment with 16-bit full adder VHDL code for beginners to learn, a good tool to learn a few power.)

说明：  In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.
