DMULS.L instructions have an MA stage for accessing the multiplier. When the second MA
of the DMULS.L instruction contends with an operating MAC.L instruction multiplier (mm),
the MA is extended until the mm ends (the M—A shown in the dotted line box in figure 7.48)
to create a single slot. When two or more instructions not related to the multiplier come
between the MAC.L and DMULS.L instructions, MAC.L and DMULS.L contention does not
cause stalling. When the DMULS.L MA and IF contend, the slot is split.
MULS.W instructions have an MA stage for accessing the multiplier. When the MA of the
MULS.W instruction contends with an operating MAC.L instruction multiplier (mm), the MA
is extended until the mm ends (the M—A shown in the dotted line box in figure 7.49) to create
