Hi, I'm trying to maximize the read bandwidth thru the High Performance (HP) DDR2 memory controller using the Stratix III devkit & the included Micron DIMM. I am getting less than I had hoped...

I would recommend the Avalon Multi-port DDR controller from Microtronix. I managed to read 512x128-bit data with one burst, in 512 clocks (continuous readdatavalid) plus around 25 clocks as read latency.

Have a look at http://www.microtronix.com/products/?product_id=92
