Consider two different implementations of the sameinstruction set architecture.

Consider two different implementations of the sameinstruction set architecture. The instructions can be divided intofour classes according to their CPI (class A B C and D). P1 witha clock rate of 2.5 GHz and CPIs of 1 2 3 and 3 and P2 with aclock rate of 3 GHz and CPIs of 2 2 2 and 2.
