用状态机对A/D转换器0809的采样控制电路的实现。工具：Quartus ii 6.0 语言：VHDL-State machine used for A/D converter sampling control circuit 0809 is achieved. Tools: Quartus ii 6.0 Language: VHDL

说明：  利用高速口GTX进行快速的数据传输，包括接受和发送模块，用途广泛(The use of high-speed port GTX for fast data transmission, including receiving and sending modules, has a wide range of uses.)

HDMI做为视频输出输入接口已经广泛使用很长时间，主要通过TMDS差分编码传输。本实验通过在HDMI屏幕上显示彩条和输入输出环通实验，来练习视频的时序和视频颜色的表示，为后面视频处理实验做个基础。(HDMI as video output input interface has been widely used for a long time, mainly through TMDS differential coding transmission. In this experiment, by displaying color bars and input/output loop experiments on HDMI screen, video timing sequence and video color representation are practiced to lay a foundation for video processing experiments later)

乘法器是硬件设计中的很常见也很重要的一个模块，它的VHDL硬件实现很好的解决了软件编程中做乘法速度慢的问题，在实时高速系统应用中或DSP软核或数字信号处理硬件实现算法中，经常能使用到乘法器，所以经典的高速乘法器IP 很有参考价值-Multiplier is a common and important module in hardware designing.Its VHDL addresses the low speed of multiplication in software programming. Multiplier is often used in real-time high-speed system application , DSP soft core or hardware implementation of digital signal processing,so it is worthful to know classic high-speed multiplier IP
