Assume a 5?stage pipeline (instruction fetch, operand fetch, execute, memory, write?back). For the following code show any stalls and indicate where operand forwarding would be needed.


ADD R9,R9,R8
MUL R1,R2,R3
LDA R5,(4,R1)
SUB R5,R5,R1
ADD R7,R8,R9
MUL R7,R1,R5


With no internal forwarding (operand fetch in bold where operand fetching is needed)





With internal forwarding (operand used in next cycle after its creation)
