这是一篇介绍用verilog语言实现viterbi译码和rake接收机的文章，实用性很强的，在这里也感谢这篇文章的作着...

1。源文件保存在src目录，QII的工程文件保存在Proj目录； 2。程序实现的功能是在VGA显示器上显示彩色条纹，共8种颜色， 可以使用嵌入式逻辑分析仪观测信号； 3。modelsim仿真文件在proj--simulation--modelsim中(1. The source file is saved in the src directory QII project file is saved in the directory Proj 2. The functionality of the program is displayed on a VGA monitor color stripes, 8 colors, you can use the embedded logic analyzer observed signals 3. the modelsim simulation files in the proj- simulation- modelsim)

verilog写的39阶通带为20KHz的半带fir滤波器，经测试正确。(verilog halfband FIR)

说明：  xilinx 平台的SPI从接口实现源码，供参考学习(used xilinx,slave-spi interface.)

说明：  图像采集 VGA输出 图像的边缘 ov7670(V image acquisition VGA output image edge)

ISE时序约束笔记——Global Timing Constraints，这个文档中详细介绍了如何使用ISE中约束工具和原理，对fpga水平提高有很大帮助(In this file , global timing constraints is introduced very clearly. It can really helps)
