Assume we need to implement the following sequence of Instructions with
forwarding by using a 5 stages pipeline.
sub x12, x11, x13
and x8 x12, x15
or x9,x16.x12
For clock cycle 5, what are the control values of A and B (the two outputs of
"Forwarding unit") respectively?
(The control values for the forwarding multiplexors
are shown in the following table)
MUX Control Source
A/B - 00
ID/EX
W/B - 10
EX/MEM
