3. When a MULS.W instruction is located immediately after another MULS.W instruction
Figure 7.66 MULS.W Instruction Immediately After Another MULS.W Instruction (IF and
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 7.65) to create a single slot. When one or more instructions not related to the multiplier
is 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.
When the MA of the MULS.W instruction is extended until the mm ends, contention between
the MA and IF will split the slot in the usual way. Figure 7.66 illustrates a case of this type,
assuming MA and IF contention.
