okaay, i have a first successful - one instruction (an add) -
execution of an "internal op" which is manually placed into the
instruction queue. adding the POWER decoder in front of that should
be a trivial exercise.
the code's been... messed about somewhat, to get it functional, and
the LDST and Branch Comp Units also need converting. however the core
out-of-order engine remains exactly the same, so this again should
just be a straightforward exercise.
we do need to write a "proper" Integer ALU - one that uses
PartitionedSignal for operations. this will be where all the pieces
and hard work that everyone's put in will gel together.
