VHDL学习总结，简要概括了VHDL，非常适合做学习的总结

这里面有许多vhdl的例子，相信对这语言的初学者受益匪浅-There are many examples of vhdl, I believe that beginners benefit from this language

使用vhdl语言在altera公司的up3板上产生vga信号，里面有详细的解析和说明，是一个很好的教程。-use of the VHDL language ALTERA company"s board up3 have vga signal containing a detailed analysis and explanation is a good guide.

成功解决FPGA设计时序问题的三大点.word说明文档，很详细(FPGA design timing problems successfully solved the three points)

DDR SDRAM的资料，有兴趣的朋友可以下下来-DDR SDRAM information, interested to see friends down under

交织器主要是对输入数据按照一定的规则打乱以便减少数据中过长的连0或者连1的出现。交织矩阵为行列矩阵，msgin为输入比特，msgout为交织输出比特，row和rol为交织器的行和列，可以通过改变col改变交织深度。先把输入的比特流数据改变为一个矩阵，再按照一定的方式输出为比特流数据

说明：  FPGA Verilog浮点数乘法运算，采用单精度浮点型小数格式，运算结果精度可设置，可封装成IP核(FPGA Verilog floating-point multi operation, using single precision floating-point decimal format, the accuracy of the operation results can be set, can be packaged into IP core)

ALTERA的FPGA的IP核的源代码,为使用ALTERA的FPGA的相关设计提供参考.-Altera FPGA IP core of the source code for the use of Altera FPGA design to provide the relevant information.

说明：  基于PCF8591数模转换和DDS技术的信号发生器系统设计(Design of Signal Generator System Based on PCF8591 Digital-to-Analog Conversion and DDS Technology)

in this code very useful for designing real number concept
