RS232协议的fpga实现

约束所有时钟（包括你的设计中特有的时钟）对准确的时序分析结果而言是必不可少的。Quartus II TimeQuest Timing Analyzer为各种各样的时钟配置和典型时钟提供许多SDC命令。(Constraining all clocks, including the clocks unique to your design, is essential for accurate timing analysis results. The Quartus II TimeQuest Timing Analyzer provides many SDC commands for a variety of clock configurations and typical clocks.)

先用Matlab理论仿真，再用Verilog语言在ISE环境下编写程序，可通过手机发送指令来控制上下变频器的参数。(Firstly, we use the theory of MATLAB to simulate, and then use Verilog language to write programs in ISE environment. The parameters of up-down converter can be controlled by sending instructions from mobile phone.)

这是一个利用verilog语言编写的信号发生器的例子，值得参考(this is a code about signal generator by VIERILOG LANGUAGE!)

频率计 测量范围1-100MHz 测量阈值0.1s 计数部分为FPGA/CPLD 语言VHDL 显示部分为51 单片机加八位数码管 语言C(Frequency meter Measuring range 1-100 MHZ Measure threshold is 0.1 s Count part of FPGA/CPLD Language VHDL Display part of 51 MCU with eight digital tube Language C)

关于FPGA针对LCD资源配置，及相关电路层次关系(LCD FPGA)

说明：  介绍了FPGA的使用以及modelsim联合synplify工具的使用方法(This paper introduces the use of FPGA and the use of Modelsim joint Synplify tool)

ＡＥＳ的Ｖｅｒｉｌｏｇ实现源码，速度还可以，ｓ盒使用ｃａｓｅ实现的，ｔｅｓｔｂｅｎｃｈ的测试数据有２百多，已经过验证。在ＤＣ　下跑到８００ｍＨＺ．

FPGA实现的卷积编码，1/2编码效率，可在此基础上改为其他码率，如2/3 3/4等

PCI slave IP core, in VHDL language ,has been verified,it is very easy to use. it is an ideal IP to study PCI,design PCI Bridge

此为数学形态滤波器消燥的代码，用于一维信号，涉及一个具体的例子，需要的话可以自己修改，修改相应的结构元素。(This is a mathematical morphology filter away dry code, used to one dimensional signal, involving a concrete example, necessary can change ourselves, change the structure of the corresponding elements)
