16-bit sdram and 32-bit opb bus

Is it possible to use the opb sdram controller with a 32-bits opb bus to a microblaze one side and a 16-bits sdram to the other side? What if I do a

32-bits access to sdram. Will the controller convert this automatically in two 16-bits cycles? The datasheet of the opb sdram controller says: "Since the sdram will always be accessed to provide data the width of the OPB bus, ...". So it looks like it will convert a 32-bits access to two 16-bits accesses, but can anyone acknowledge this?

Hello Frank,

You are exactly right - the OPB SDRAM controller will convert the 32-bit access on the OPB bus to two 16-bit accesses to the SDRAM. (it actually looks like a SDRAM burst of 2).

Thanks! anita
