pex8311代码实现 altera的fpga 代码编程 实现本地读写 pex8311_test

递增方式在4位数码管上向上计数显示从0000-0001->0002……..9999….0000….0001…. -- 利用CPLD设计了一个4位十进制计数器，并用数码管显示当前计数值-Incremental approach in the four counts upward digital tube display from 0000-0001-

自适应滤波，对输入信号进行选择性的加权处理，使输出达到最优化，并且能够跟踪和适应系统和环境的动态变化(Least mean square，of the input signal processing, selective weighted output, and optimize can track and adapt to the dynamic changes of the system and environment)

代码用两种方法设计了一个基于多相滤波的内插器，低通滤波器采用128阶凯撒窗，内插倍数32，并且给定信号范围，验证了内插器的正确性，画出了内插前后信号的频谱。(The code design the interpolator based on polyphase filter using two methods.The low pass filter is 128 order Caesar window and interpolation multiple is 32.I give the range of the signal to verify the interpolator and plot the spectrum of the signal before and after the interpolator. )

网上流传的用来实现FPGA驱动VGA，从而实现一个pingpong小游戏的源码，实测可用。(a program embedded in a FPGA in order to drive the VGA and realize a little game named pingpong. tested.)

RS(255,223)编码器程序 从一本书上看到的，很不错的(RS(255,223) encode , very good good good )

SoC-Wishbone System IP核的VHDL语言源代码，需要的开发环境是QUARTUS II 6.0。(SoC-Wishbone System IP core VHDL language source code, the need for the development environment is QUARTUS II 6.0.)

两篇中文论文，详细叙述了Farrow滤波器的设计方式和理论基础，非常实用！(Two Chinese papers, described in detail Farrow filter design methods and theoretical foundation, very useful!)
