PowerPC_DDR_controller

Has anyone use the PLB DDR controller for the PowerPC in the EDK 7.1? I have implented it in my design and it takes 150 clock counts for the PowerPC to read or write data in the DDR memory. I think its too slow!


Probably you don't have the burst option enabled. It will cost a few more LUTs, but as you've seen, performance is disastrous without it.
