Multiple-output custom instructions in Nios-II

Hi there

i guess some people here work with Nios-II and SoPC builder. I have a question regarding the potential use of the internal register file.

The internal register file is useful for performing multi-cycle operation for user-supplied custom instructions. Is it possible to implement a custom instruction as the following:

(out0,out1,out2) <- function-of(inp0,inp1,inp2,inp3)

I mean is it possible to commit the output operands (out0-out2) in 3 consecutive cycles?

thanks in advance
