In this exercise, we examine how data dependencies affect execution in the basic 5-stage pipeline described in Section 4.5. Problems in this exercise refer to the following sequence of instructions: Also, assume the following cycle times for each of the options related to forwarding: Without forwarding With Full forwarding 250ps 300ps

a) How many RAW data dependencies are there?

b) How many WAR data dependencies are there?

c) How many WAW data dependencies are there?

d) What is the total execution time of this instruction sequence without forwarding and with full forwarding?

7) In this exercise, we examine how data dependences affect execution in the basic 5-stage pipeline described in Section 4.5. Problems in this exercise refer to the following sequence of instructions: or rl,r2,r3 or r2,rl,r4 or rl,rl,r2 Also, assume the following cycle times for each of the options related to forwarding: Without forwarding 250ps With Full forwarding 300ps a) b) c) d) How many RAW data dependencies are there? How many WAR data dependencies are there? How many WAW data dependencies are there? What is the total execution time of this instruction sequence without forwarding and with full forwarding
