Draw the timing diagrams for the following cases.

40 beq $2, $3, 7 /* if equal jump to 72= 28+44

44 add $4, $2, $3

48 add $7, $5, $6

52 add $4, $2, $3 :

72 add $4, $4, $3

i) The pipeline uses no enhancement for any instruction (i.e., no forwarding, no moving branch test to ID stage).

ii) The pipeline moves the branch test to ID stage.

iii) The pipeline uses dynamic branch prediction at IF stage. Assume branch is predicted to be taken and is in fact taken in the execution.
