A MULS.W instruction has an MA stage for accessing the multiplier. When the MA of the
MULS.W instruction contends with an operating MAC instruction multiplier (mm), the MA is
extended until the mm ends (the M—A shown in the dotted line box in figure 7.27) to create a
single slot. When two 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. When the MULS.W MA and IF contend, the slot is split.
