每个代码见压缩包内文件名，分别为使用单片机控制AD9627的代码，已在硬件电路实现；基于FPGA的DDR SDRAM控制源代码，将文件夹内文件加入同一工程即可；以及三份FPGA内部学习资料。

C代码开发环境为KeilC，verilog代码开发环境为Quartus。

-See each code within the compressed package file name, respectively, for the use of the AD9627 single-chip control of code, has been in the hardware circuit　FPGA-based DDR SDRAM control source code, will be adding a document folder to the same project　and three FPGA internal learning materials. C code development environment for KeilC, verilog code development environment for the Quartus.
