Question

Consider the following MIPS segment code when answering the questions below:

sw $t5, 0($t2)

sub $t3, $t1, $t6

lw $t1, 12($t5)

or $t5, $t1, $t3

Consider running this code on the 5-stage pipelined processor that does not support forwarding and hazard detection. What is the total number of cycles required to execute this code?
