Section 7 Pipeline Operation
2. When a MAC.W instruction is located immediately after a MAC.L instruction

When the second MA of the MAC.L instruction is extended to the end of the mm, contention
between the MA and IF will split the slot in the usual way. Figure 7.46 illustrates a case of this
type, assuming MA and IF contention.
When the second MA of the MAC.W instruction contends with the mm produced by the
previous multiplication instruction, the MA bus cycle is extended until the mm ends (the M—
A shown in the dotted line box in figure 7.47) to create a single slot. When two or more
instructions that do not use the multiplier occur between the MAC.L and MAC.W instructions,
the stall caused by multiplier contention between MAC.L instructions is eliminated.
