UART 完整

read data of type character from flash memory

本代码实现一个fir滤波器，结合matlab对数据进行进行验证，最后用modesim对编写的代码进行仿真，最终用matlab和fpga实现一个功能正常的fir低通滤波器，这里附有源代码，并且用verilog代码编写，具有很大的参考作用对于刚学习fpga的朋友，希望你们能真正的对所学的东西感兴趣，这个是我上传代码的初衷，希望你们学业进步，继续做一个对技术有信心的人才。

verilog编码器、计数器、加法器的程序(Verilog encoder, counter, adder procedures)

本代码实现了sd卡接口驱动功能，实现了在sdmode下50Mbps的读写速率，也可以通过添加额外的命令来实现100Mbps的速写速率，而文件系统的实现可以在本接口的基础上来轻松完成，从而实现针对你的应用所需要的功能，本代码非常易读，大家可以轻松看懂！

说明：  emif接口转axi接口，在多个项目中使用，功能完善(EMIF interface to Axi interface, used in many projects, perfect function)

《数字信号处理的FPGA实现（第三版）》作者：U.Meyer-Baese 的配套源码，基于quartus9.0编写，使用的cyclone ii。其中包含FIR IIR FFT等算法的实现，对学习图像处理很有帮助。( FPGA digital signal processing (third edition) Author: U.Meyer-Baese The matching source, based on quartus9.0 preparation, the use of cyclone ii.

design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip’s SPI MCP3202 12-Bit A/D converter. The 8 most significant bits of the converted data will be displayed on two seven segments of the NIOS development board. The sampling frequency is 20kHZ. Use a potentiometer.(design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip' s SPI MCP3202 12-Bit A/D converter.
