1. When a MAC.W instruction is located immediately after another MAC.W instruction
When the second MA of a MAC.W instruction contends with an mm generated by a preceding
multiplier-type instruction, the bus cycle of that MA is extended until the mm ends (the M—A
shown in the dotted line box below) and that extended MA occupies one slot.
If one or more instruction not related to the multiplier is located between the MAC.W
instructions, multiplier contention between MAC instructions does not cause stalls (figure
7.24).
Sometimes consecutive MAC.Ws may not have multiplier contention even when MA and IF
contention causes misalignment of instruction execution. Figure 7.25 illustrates a case of this
type. This figure assumes MA and IF contention.
