Timing Notes:
5 . Five major cycles for instruction set-up and exit. One major cycle per word
(nonconflict case) or two major cycles per word (conflict case).
Nonconflict case occurs when two PPs communicating to each other are not in
the
slot at the same time.
Conflict case occurs when two PPs communicating with each other are in the slot at
the same time.
