$1)$ Indicate dependences and their type.

$2)$ Assume there is no forwarding in this pipelined processor.

Indicate hazards and add nop instructions to eliminate them.

$3)$ Assume there is full forwarding. Indicate hazards and add NOP instructions to eliminate

them.

$4)$ What is the total execution time of this instruction sequence without forwarding and with

full forwarding? What is the speedup achieved by adding full forwarding to a pipeline that

had no forwarding?
