Pipelined Datapath Custom Instructions

I've been looking for a while to find some information and tutorials on how to run pipelined custom instructions. Let's say we have (A+B) * (C+D) and we have 10 values for each of A,B,C,D, so 4...

The problem can be if you have to access to the external memory in order to load A,B,C,D data.
