Figure 7.93 TRAP Instruction Pipeline
The pipeline has nine stages: IF, ID, EX, EX, MA, MA, MA, EX, and EX (figure 7.93). The MAs
do not contend with IF. TRAP is not a delayed branch instruction. The two instructions after the
TRAP instruction are fetched, but they are discarded without being executed. The IF of the branch
destination instruction starts from the slot of the EX in the ninth stage of the TRAP instruction.

Figure 7.94 SLEEP Instruction Pipeline
The pipeline has three stages: IF, ID and EX (figure 7.94). It is issued until the IF of the next
instruction. After the SLEEP instruction is executed, the CPU enters sleep mode or standby mode.
