The lui instruction in the following instruction sequence is fetched in cycle 1 on our pipeline that includes both a data hazard unit and a forwarding unit. Indicate the total number of clock cycles consumed by this code running on the pipeline. The bltz instruction IS a delayed branch which branches to the instruction with label loop if register $12 contains a value that is less than 0. Explain your answer.

lui $4,0x400C

ori $4, $4, 0x2000

addiu $12, $0, -392

addu $8, $4, $12

nop

loop:

lw $14, 0($8)

lw $16, 400($8)

addu $14, $14, $16

sw $14, 800($8)

addiu $12, $12, 4

bltz $12, loop

addiu $12, $12, 4

xor $12, $12, $12

nop
