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
