thanks for answer.

You're right I'am a little bit confused about this solution.

byteenable should be 8bytes, I understand. but how all operation of data transfer should look like?

To send 64-bit vector from nios to slave input

do i have to do it like this:

set the byteenable to 0000_1111

send 64-bit data (the master will send first 32-bit)

then

set the byteenable to 1111_0000

send 64-bit data (the master will send last 32-bit)

am i right or did i missunderstood the whole process?

Maybe there is a easier solution for such transfer?
