用VHDL编写的关于SCAN的一个小程序，希望大家看了后能喜欢，也可以学学哟！...

FPGA三国论战，入门介绍和高端见解！对于FPGA初学者很有用。(Three FPGA controversy, and high-end introduction to ideas! For FPGA useful for beginners.)

可以产生正弦波，三角波、锯齿波、方波，要求频率1Hz-100kHz，步进1Hz，具有自动扫频功能； 正弦波的相位可调，方波的占空比可调； (Can generate sine wave, triangle wave, sawtooth wave and square wave, the required frequency of 1 hz- 100 KHZ, step 1 hz, with functions of automatic frequency sweep The phase adjustable sine wave, square wave duty ratio is adjustable )

讲述软解调很不错的一片文档，主要阐述的是8PSK的软解调FPGA实现，但对8PSK的软解调原理阐述很清楚，没有多余的东西，但需要注意其中各个调制符号点得顺序。(About soft demodulation of a document is very good, mainly on the soft 8PSK demodulation FPGA, but soft 8PSK demodulation principle describes very clearly, no extra stuff, but need to pay attention to the point where each modulation symbol was in order.)

基于System Generator的图像处理工程,多媒体处理FPGA实现的源码,图像形态学部分,腐蚀,膨胀,细化算法(System Generator based image processing engineering, multimedia processing FPGA implementation source code, image morphology section, corrosion, swelling, thinning algorithm)

FPGA开发超声波测距，可改写工业探伤或倒车测距等系统，quartus2下选择EP2C5Q208C8（CycloneⅡ） 支持目前淘宝上能买到的所有4-5针超声波模块 应用cycloneⅡ自带除法模块 开发板为有光技术YG2.1 生成电路规模较小 ！！注意：移植程序仅需重新约束数码管和超声波模块的针脚 (Ultrasonic Ranging FPGA development, industrial inspection or reverse rewritable ranging systems, EP2C5Q208C8 (CycloneⅡ) under quartus2 4-5 needle ultrasonic module supports all currently scouring the treasure can buy Applications cycloneⅡ own division module Development board bright technical YG2.1 Small scale generating circuit ! ! Note: The migration program only re-constraint digital and ultrasonic modules Pin)

基于fpga的多功能数字时钟的实现，已经编译过了，绝对可行-fpga-baseed clock

低密度校验码 ，很好用的代码，功能已经实现编码和译码(fpga ldpc)

ULTRACTR的源码，xps工程实现，基于PPC平台-ULTRACTR source code, xps engineering, based on the PPC platform

Xilinx FPGA 时序约束资料，原厂出品，经典不需要理由(Xilinx FPGA timing constraint information, original, classic no reason)

用MSP430进行压力测试，完成数据的分析(with msp430 to continue on press test.to complete about the anlysys about data)
