交通灯 verilog

在zedboard开发板上采用vivado通过AXI进行DMA数据传输(Using vivado to transfer DMA data through AXI on zedboard development board)

用verilog实现双口ram读写程序，本程序含用工程文件，且已经过工程仿真，代码可以直接调用，方便新手学习，如果有问题，大家可以相互讨论.

说明：  FPGA锁相环实验： 顶层文件加底层IP文件构成 top中例化ip核pll(Experiment of Phase-Locked Loop Based on FPGA)

本程序包含：EEPROM的功能模型(eeprom.v)、读/写EEPROM的verilog HDL 行为模块（eeprom_wr.v）、信号产生模块（signal.v）和顶层模块(top.v) ，这样可以有一个完整的EEPROM的控制模块和测试文件，本文件通过测试。(This procedure includes: EEPROM of the functional model (eeprom.v), read/write EEPROM acts of verilog HDL modules (eeprom_wr.v), signal generator module (signal.v) and top-level module (top.v), this can have a EEPROM complete control module and test document, this document is to pass the test.)

DAC0832 接口电路程序.功能：产生频率为762.9Hz的锯齿波DAC0832VHDL程序与仿真(DAC0832 procedures interface circuit. Functions: generate the sawtooth frequency of 762.9Hz and simulation procedures DAC0832VHDL)

本代码是cache代码，采用最近最少使用算法。代码量大约1000-2000行，程序包括cache替换算法的实现。映像规则的选择，以及全部的仿真程序。

基带数字信号通过成形滤波（选用升余弦滚降函数）然后进行载波调制(Base-band digital signal through the shaping filter (raised cosine roll-off optional function) and then proceed to carrier modulation)

SPI协议的VHDL/Verilog语言实现。(SPI agreement VHDL/Verilog language.)

初学学习verilog的经验，可以帮助新手以正确的思维方式，学习方法学习。(Verilog learning experience)

FPGA／CPLD技术是近年来计算机与电子技术领域的又一场革命。本书以Xilinx与Altera公司的FPGA／CPLD为主，详细介绍了FPGA／CPLD从芯片到MAX+plusⅡ、Quartus与ISE开发环境和Verilog／VHDL语言，并以交通灯逻辑控制、电子钟与点阵LED显示、LCD液晶显示及计算机ISA接口和PCI接口的设计等为例，由浅入深地详述了如何应用FPGA／CPLD进行电子设计。书中的大多数电路图和源程序已经过实例验证，读者可以直接应用于自己的设计。本书的特点是强调实用性和先进性，力求通俗易懂。 本书适用于计算机、电子、控制及信息等相关专业的在校大学生，对广大工程技术人员也具有实用价值。(FPGA/CPLD technology in recent years the field of computer technology and electronic another revolution. Book Xilinx and Altera' s FPGA/CPLD based, detailing the FPGA/CPLD from the chip to MAX+plus Ⅱ, Quartus and ISE development environment and Verilog/VHDL language and logic control traffic lights, electronic bell with dot matrix LED display , LCD liquid crystal display and computer ISA interface and PCI interface design, for example, progressive approach to detail how the application of FPGA/CPLD for electronic designs. Circuit and the source of most of the book have been instances of verification, the reader can be directly applied to their own design. Characteristic of this book is to emphasize the practical and advanced, best straightaway. This book applies to computers, electronics, control and information and other related professional college students, the majority of engineering and technical personnel also has practical value.)
