For the following two sequences of instructions:
a:
LW $t0, 0 ($sp)
ADD $t0, $t0, $t0
SW $t0, 0 ($sp)
b:
ADD $t0, $a0, $a1
SUB $t1, $t0, $t1
ADD $t2, $t0, $t1

Use the given clock cycle times to answer the following questions Without Forwarding With ALU-ALU Forwarding With full forwarding 250 ps 275 ps 300 ps 3.1. What is the total execution time of each instruction sequence without forwarding and with full forwarding? What is the speed-up achieved by adding full forwarding to a pipeline that had no forwarding? 3.2. Add NOP instructions to this code to eliminate hazards if there is ALU-ALU forwarding only (no forwarding from the MEM to EX stage.) 3.3. What is the total execution time of each instruction sequence with only ALU-ALU forwarding? What is the speed-up over a pipeline without forwarding?
