Question: Consider a program running on an AMD Barcelona with an instruction count of 2.389E12 and an execution time of 750 s. (a) Find the CPI

Consider a program running on an AMD Barcelona with an instruction count of 2.389E12 and an execution time of 750 s. (a) Find the CPI if the clock cycle time is 0.333 ns. (b) If the program is made of three classes of instructions A, B, and C, half of the instructions are in class A, 20% are in B, and the rest are in C, find the CPI of class C instructions assuming that CPIA = 0.9 and CPIB = 1.05. (c) Find the increase in CPU time if the number of instructions of the program is increased by 10% without affecting the CPI.
