Notes:
• In the rel11 and rel8 fields of the hardware specifications, the assembler calculates values and sets them as shown below:
(label12-PC-2)/2 → rel11, (label9-PC-2)/2 → rel8; label12 and label9 have a sign.
• A delayed branch always occurs after the next instruction (delay slot) is executed.
• Instructions that can be placed in the delay slot are all 1-cycle, a-, b-, c-, and d-cycle instructions.
Multicycle instructions cannot be placed in the delay slot.
