1> the uart rs232 available in sopc are without fifo is it possible to add fifo by modifying the same uart core[/b]
--- quote end ---
that uart's code is generated on-the-fly by the sopc builder, so you could modify it, but it would be tricky, and you'd have to figure out a way to keep your changes from being overwritten when the sopc gets regenerated. good luck there.

--- quote end ---
not that i'm aware of. there are free cores, and cores that integrate with sopc builder, but not both.

usually the ip data sheet gives some clue to this.

maybe. assume it's going to need a driver unless you can find one out there already.

- apprx how much design time it will take to
design hdl uart, device driver for a single person?
--- quote end ---
a while. this depends on many unmeasurable factors, so i couldn't give you a number. but it won't be easy.
<!--quotebegin-prasad_forums@Oct 26 2005, 01:03 AM i think in sopc builder when we instantiate uart
we get tab which asks for fifo size as it is in built.
