SDRam Controller is there a better one ?

Hi,

Having some imilar issues, I did some tests on the SDRAM controller.

Yes there are better controllers, but the bottleneck is most of the time the clock domain crossing :

-> running the SDRAM controller on 160Mc (better usage of the memory bandwidth) and the processor on 50Mc gives a slower system due to clock synchronisation.

-> maybe a solution like the SDRAM controller from Microtronix can give you some speed advantages : 2 slaves on one controller, so if both the cpu and the other masters are working on a slower speed, the SDRAM controller can keep up due to its higher bandwidth on a higher clock speed. But here also, the clock synchronisation must been done.
