In this exercise, we exаmine hоw dаtа dependencies affect executiоn in the basic 5-stage pipeline described. Prоblems in this exercise refer to the following sequence of instructions:Instruction 1) lw r1,r2,r3Instruction 2) add r2,r1,r4Instruction 3) and r1,r1,r2Also, assume the following cycle times for each of the options related to forwarding:Without forwarding: 250psWith forwarding: 300ps (a) [4 points]Indicate dependences and their type (type mean: Data hazard with sub-category: Read before Write, load and use, etc.)(b) [4 points] Assume there is no forwarding in this pipelined processor. Indicate hazards and add stalls to eliminate them.(c) [4 points] Assume there is full forwarding. Indicate hazards and add stalls to eliminate them. (when answering forwarding options please mention whether the forwarding is from EX/MEM to EX/MEM or MEM/WB to EX/MEM for all the cases of hazards mentioned in (a))(d) [4 points] What is the total execution time of this instruction sequence without forwarding and with full forwarding? Please use the clock cycle time mentioned above. [Hint: Calculate the total number of clock cycles needed with stall and then multiply with the above times(250 or 300ps based on case) to find out the total time needed to execute the program. You should get the total number of cycles needed without forwarding from (b) and with forwarding from (c)](e) [4 points] What is the speedup achieved by adding full forwarding to a pipeline that had no forwarding? [Hint: The ratio of the above two quantities is calculated in (d). time for Without forwarding/time for with forwarding]
