SHORT ANSWER:
Given the following MIPS code:
lw $s1, 0($s5)
add $t0, $s1, $s2
beq $t0, $t1, next
sub $t2, $t1, $t0
addi $t2, $t2, 1
j after
next: sw $s1, 20($t1)
after: sw $t0, 0($s5)
Considering the above code, and a multi-cycle processor. In which cycle of the program run does the ALU add the values from registers $s1 and $s2? Assume the first instruction starts running in cycle 1.
Explanation / Answer
Answer
By the instructions given in the cycle 2 ALU adds the values from registers $s1 ans $s2 and then stores in $s2 registers as given instruction.
