Figure 8.56 Example of No Multiplier Lock Contention when Following Instruction is
If the following instruction is an instruction in category “Register write instructions (II),” it is
executed when there is one slot remaining in the lock interval (figure 8.57).
STS and STS.L instructions do not lock the multiplier. Therefore, parallel execution is
possible for an STS instruction and MUL.L instruction, etc.
