Description Luke Kenneth Casson Leighton 2019-06-28 07:26:43 BST
special-cases do not need to go through the pipeline.  however this means
that two results can be generated in one clock.  fortunately, the muxid
protects two results from occurring with the same muxid (Fan-in, Fan-out
ReservationStation class).
