Since the ROB is a FIFO-Buffer we need to put new entries at the bottom of the table.
In WB I move the value of the topmost Entry in the ROB to the given Register and set the bsy-flag to 0
So far so good
Now I want to add a new Entry.
But of course I can't put that one on the top
So my question is, if I need to move all Entries one up or if I need to wait till the whole ROB is empty so I can put new Entries in there.
Of course the assumption is that the ROB is full at the beginning,
