MULS.W instructions have an MA stage for accessing the multiplier. When the MA of the
MULS.W instruction contends with the operating multiplier (mm) of another MULS.W
instruction, the MA is extended until the mm ends (the M—A shown in the dotted line box in
figure 7.56) to create a single slot. When two or more instructions not related to the multiplier
are located between the two MULS.W instructions, contention between the MULS.Ws does
not cause stalling. When the MULS.W MA and IF contend, the slot is split.
