 yehyeh, that's going to get interesting.  i'd be really interested to
see what happens on putting some data into the pipe.

 see fpmux.py btw - it does ready_io/valid_io signalling.  if you
ignore that, something similar can be used (one cls.send, one cls.rcv
function) to get an array of data into the pipeline (cls.send), and in
cls.rcv, delay by N fixed cycles (to wait for pipe propagation), and
start reading out of the pipeline.
