The single thread performance of processor generally increases with the area of the processor.
Consider that in the technology node available to us the singlethread performance of a core
increases with the square root of the area. For example, if you increase the area of a core by four
times, the performance doubles. You are analyzing the performance of three processors P P and
P that have different area for a single core as follows:
P: Single core area A
P: Single core area A
P: Single core area ANow assume that you have an area budget of A You can utilize this area to include multiple
cores of the same type, eg cores of P or cores of P Which of the three processors
will give the maximum speedup in this case? What is the speedup with respect to a single
processor P The workload is same as that of part a ie the serial portion is S
c Finally, you build a heterogeneous system that has one processor P and processor Ps
total area is A Now the serial portion is of the workload is running on P while the parallel
