Question

This is a question for a Computer Organization course:

Answer the following with 1 to 2 short SENTENCES for full credit:

1. What is a multicycle datapath, and what does it do?
2. What are the advantages and disadvantages of a single-cycle datapath?
3. What is forwarding in a pipeline processor?
4. What is Branch Delay Slot?

Answer 1

Answer)

A) Multicycle implementation is the break up of the instruction as separate steps where each step would take the single clock cycle where each functional unit can be used for more than one of its instruction as it is being used for different clock cycles which helps in reducing the average instruction time.

B) Advantages and disadvantages of a single-cycle datapath

This accommodates the inputs which are being used for in different ALU . This doesn't need any separate adders for the PC or the branch calculations

The disadvantage is it has many different temporary registers available on it.

C) The operand forwarding is considered as an optimization in the CPUs pipelined to limiting the performance deficits which happen due to pipeline stalls. It is the data hazard which is responsible for leading to the pipeline stalls while the current operation gets to wait for the results of the earlier operation which is yet to be over

D) The branch delay slots are considered when the branch instruction gets involved, it is the location of the following delay slot instruction which is called the branch delay slot.
