I am using Artix 7 FPGA Nexys 4 DDR and using MIG to access DDR memory. I am supplying 200MHz clock to MIG and uisng AXi bus to write data. The data wrties to the DDR (2MB) is very slow. I am wrting video frame data to DDR. It takes TFT controller to write the frame 15.8ms. DDR wtire is takes about 333ms to wrtie one frame to DDR memory. Is there any way to speed up DDR writes using AXI bus interface? I have attached a picture of my harware setup. Any pointers to get the DDR memory write speed up? Thanks
