用Verilog实现的八位存储器参考代码

1、用状态机设计A/D转换器ADC0809的采样控制电路，并在数码管上显示转换结果； 2、设置有复位和启动/保持开关，要求 ⑴ 复位开关用来使A/D转换器复位，并做好A/D转换准备； ⑵ 启动/保持开关用来控制A/D转换器开始连续转换或停止转换保持结果，即按一下启动/保持开关，启动A/D转换器开始转换，再按一下启/停开关，停止转换并保持结果。 3、采用Verilog HDL语言设计符合上述功能要求的控制电路。(1, with the state machine design A/D converter ADC0809 sampling control circuit and display the results on the digital conversion 2 is provided with a reset and start/hold switch, reset switch is used to make the request ⑴ A/D converter reset and do A/D conversion ready ⑵ start/hold switch is used to control the A/D converter starts converting or stop the conversion to maintain a continuous result that by clicking Start/hold switch, start the A/D converter to start the conversion, and then Click the start/stop switch stops the conversion and keep the results. 3, using Verilog HDL language designed to meet the functional requirements of the above-mentioned control circuit.)

说明：  FIFO: First in, First out 代表先进的数据先出，后进的数据后出。Xilinx 在 VIVADO 里为我们已经提供了 FIFO 的 IP 核, 我们只需通过 IP 核例化一个 FIFO，根据 FIFO 的读写时序来写入和读取FIFO 中存储的数据。(FIFO: first in, first out represents the first out of advanced data, and the last in data is the last out. Xilinx has provided us with the IP core of FIFO in vivado. We only need to instantiate a FIFO through the IP core, and write and read the data stored in FIFO according to the FIFO read-write timing.)

基于ad7470，ad5331的数模转换和模数转换的采集系统，已通过modelsim和quartus验证，输入0到2.5v的正弦波波形，转换输出通过采集卡的波形基本类似。

基于VHDL语言的CORDIC算法实现，用于计算sin(x),cos(x)等，实测可用(Based on VHDL CORDIC algorithm, used to calculate sin (x), cos (x), etc., the measured available)

nova是一个低功耗的H.264/AVC基线解码器，面向移动应用。它是一种专用的、全硬连线的ASIC设计，不使用任何GPP/DSP核心。H.264硬件编码器被设计成一个模块化系统，具有小型、高效、低功耗的组件，可以完成定义良好的任务。设计的主要目的是使一个可伸缩的编码器适用于百万像素的图像，适用于相机头和低功耗录像机。

说明：  All AMBA bus protocols - AXI3, AXI4, AXI4-Lite, ACE, AHB

说明：  学习使用quartus modelsim(learn to uee quartus modelsim)

如果需要用verilog设计一项比较简单的功能，那么这个浅显易懂的程序能让你很快明白点阵的设计方法，尤其是对那些初学者(If you need to use a relatively simple verilog design features, then this easy to understand design of the program allows you to quickly understand the lattice method, especially for those who are beginners)
