fpga通过usb 向电脑发送计数器的数据

SPI slave接口协议，基于verilog，调试可用

说明：  使用DDR3IP核进行仿真，写入读取数据(Using DDR3IP core to simulate, write and read data)

一个解决除法溢出的例子，可以学习到很多，注释很详细(A solution to the division overflow example, you can learn a lot, very detailed notes)

Set a bit and return its old value.

这是一个nios工程，控制TFT液晶屏的程序。FPGA平台用Verilog HDL语言编写的，MCU软核程序有C语言编写。通过这一个完成的工程，你就会明白SOPC的一些实现方法。(This is a nios engineering, control TFT LCD screen program. The FPGA platform Verilog HDL language preparation with the nuclear program has a soft, MCU written in C language. Through this a complete project, you will understand some of the SOPC methods of realization. )

Reed-solomon decoder, encoder design note

采用xilinx的ROMIP核产生类似正弦信号，经过FFt后可以观察结果(Using the xilinx ROMIP nuclear generating similar sinusoidal signal can be observed through the results after FFt)

IT IS THE DP MEMORY MODULE. IT CONTROLS THE DP MEMORY

说明：  FPGA串口实现。 发送和接受数据功能代码(FPGA serial interface. Send and receive data function code)

说明：  编码方式为213的Viterbi卷积码编码器和译码器的FPGA的实现，包含整个QuartusＩＩ的工程文件，解码方式为寄存器交换法(Encoding for the 213 convolutional code encoder and Viterbi decoder FPGA realization of the project file that contains the entire QuartusII, decoding method for the register exchange)
