verilog语言ddr3读写程序，axi总线协议，用于ddr3读写测试-ddr3 read and write

利用Spartan6的软核MicroBlaze来测试读写DDR3的历程。利用官方提供的函数以及实时查看内存来验证DDR3的读写是否成功-Use of Spartan soft-core MicroBlaze 6 to test reading and writing DDR3 course. The use of official functions and real-time view to validate DDR3 memory read and write was successful

DDR3读写在FPGA上的实现代码，经测试通过-DDR3 read and write FPGA implementation of the code, the test passed

ddr3 sdram 功能测试。读写测试还有自刷新测试，测试通过。-ddr3 sdram test,write and read ,aoturefresh
