Given : Instruction Type 1, 2, and 3 on Machine M           …

Given : Instruction Type 1, 2, and 3 on Machine M             CPI1 = 1; CPI2 = 3; CPI3 = 4 Answer with just a number a. What is Average CPI of machine M running a program P that has 29% Type 1 instructions, 31% Type 2 instructions, and the remainder Type 3 instructions? Answer with just a number. b What is the execution time if  program P has 20000 instructions and machine M has a clock rate of 5 GHz? Give your answer in microseconds. Just a number no units. c. What is the speedup if M’s clock rate is improved to 7.5 GHz. Just a number.   d. What is the speedup from the original time calculated in part b if the clock rate is improved to 7.5 GHz and type 3 instructions are improved to 2 CPI? Just a number.  Three numbers after the decimal point.
