i've found the sdram controller performance to be pretty awful. given

the logic area it occupies and its performance, i no longer consider it a

viable alternative for many new designs.

i've switched to psram (pseudo sram) for new designs. it eliminates

the sdram controller and it performs better[/b]. The cost is

very attractive ... the expense is the number of pins you must use.
