Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (classes A, B, C, and D). P1 with a clock rate of 2.0 GHz and CPIs of 1, 2, 2, and 1, and P2 with a clock rate of 4 GHz and CPIs of 2, 3, 4, and 4.
Processor Class A Class B Class C Class D
P1 3 2 1 4
P2 2 2 2 2
Given a program with a dynamic instruction count of 1.0E5 instructions divided into classes as follows: 10% class A, 30% class B, 40% class C, and 20% class D.
1. Which implementation is faster?
2. What is the global CPI for each implementation?
3. Find the clock cycles required in both cases?

Geneva’s manager would like to see some additional information to make sales decisions.enter a formula in cell j4 using the if function to it whether or not the item beaded earrings should go on sale. it will go on sale if its current sales rank (in cell g4) is 8th or lower. (hint: if the cell value is greater than or equal to 8, it will go on sale.)if this condition is true, the item will go on sale. (hint: the if_true value should be “yes”.)if this condition is false, the item doesn’t need to go on sale. (hint: the if_false value should be “-”.)copy the formula created in cell j4 to the range j5: j14
