3. Compute the total execution time for a single cycle architecture. The cycle time is 5-cycles. 5 + 10 = 10 ADDI $50, $t0,50 SW $50, 8($t1) ADD $51, $50, $t2 BEQ $s2, $s1, 10 SUB $s3, $s2, $50 AND $54. $s3. $53 OR $55, $s6, $s7 [$s2 and $s1 are not equal] Now you want to improve the performance/reduce the execution time through multi-cycle pipeline. Assume each stage takes 1-cycle. Also, assume no hazard optimization technique (as example NO forwarding or rescheduling etc.) has been implemented in this architecture. What will be the new execution time
