JUART / nios2-terminal bandwidth limit

We are trying to use a part of a StratixII as a RS232 server : - 6 uarts, at 9600 baud, are connected to the outside world : actual computers - Data from the 6 uarts are "routed" by a NI...

you did not say which software are you using on the device... is it the standard altera hal?

did you try to use non-blocking writes?

what do you use for the communication among the two cpus?

I am prototyping with the StratixII (DSP) evalboard, and stock drivers/libs are used.

The data flow ( unidirectional for now ) :

2nd Nios2 -> UARTs -> UARTs -> Routing Nios2 -> JUARTs -> nios2-terminals

There is no commuication between the NIOS2s

All read/write by the "Routing Nios2" to the juarts/uarts are non-blocking.

Read/write by the "2nd Nios2" are blocking calls.
