MULS.W instructions have an MA stage for accessing the multiplier. When the MA of the
MULS.W instruction contends with an operating MAC.W instruction multiplier (mm), the MA
is extended until the mm ends (the M—A shown in the dotted line box in figure 7.37) to create
a single slot. When one or more instructions not related to the multiplier come between the
MAC.W and MULS.W instructions, MAC.W and MULS.W contention does not cause
stalling. There is no MULS.W MA contention while the MAC.W instruction multiplier is
operating (mm). When the MULS.W MA and IF contend, the slot is split.
DMULS.L instructions have an MA stage for accessing the multiplier, but there is no
DMULS.L MA contention while the MAC.W instruction multiplier is operating (mm). When
the DMULS.L MA and IF contend, the slot is split (figure 7.38).
