DDR2 SDRAM CONTROLER

用Verilog实现的脉冲宽度调制程序，在quartus平台上测试成功。(Using Verilog implementation of pulse width modulation, in quartus platform test successfully.)

本文分析了当前国内外出租车计费系统的基本组成和工作原理及主要的两种设计方式:基于单片机的设计方式和基于FPGA的设计方式；并对这两种实现方式的优点和缺点进行分析，比较后确定本系统的方案：基于FPGA的出租车计费系统的设计。(This paper analyzes the current taxi charging system at home and abroad, working principle and basic components of two major design approach: the design methods based on single chip FPGA-based design approach and the two implementations to analyze the strengths and weaknesses, After comparing the program to determine the system: FPGA-based taxi billing system.)

fpga 控制ad7606，编写代码用verilog语言，实现采集函数发生器

说明：  掌握SDRAM数据读写、刷新、初始化以及FPGA串口收发时序，熟练FIFO IP核的生成和调用。(Master SDRAM data read and write, refresh, initialization and the timing of sending and receiving of the serial port of the FPGA, skilled in the generation and invocation of the FIFO IP core.)

Everspin SPI MRAM chipset(MR25H10,MR25H40,MR25H256)

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).)

利用IIC接口的4路 ADC max1037，采集思路信号，通过在FPGA内部的构建DeltaSigma DAC软核，在VGA液晶显示屏上显示波形。 (IIC interface 4-way ADC max1037, collecting ideas signal the FPGA internal build DeltaSigma DAC soft-core VGA LCD display waveforms.)

VGA显示原理与VGA时序实现论文,详细介绍了VGA的原理 (Principle and VGA VGA display timing to achieve paper, detailing the principles VGA)

quartus 的220model 与 altera mf的库 用于fpga的modelsim仿真过程中添加到工程里面(the libary of 220 model and altera mf when we simulate the fpga project by modelsim)

这是 ；一种缓存设计的Verilog代码，使用先进先出算法。大约2000行代码，该程序包含缓存替换算法的实现。图像规则的选择，以及所有的模拟。这个设计有很多模块。这是缓存的主要模块。
