A processor with a clock rate of 3 GHz has a CPI of 6 for a particular program. What is the MIPS rating for this program? Answer: If the length of a clock cycle is 0.4 nanoseconds, what is the clock rate in GHz? Answer: Consider a system with only two types of instructions, A and B. Type A instructions each require 7 clock cycles, while type B instructions each require 2 clock cycles. The CPI for a particular program when executed on this system is 5. What must be the fraction of instructions executed that are of type A? (Give your answer as a decimal number to at most two decimal places, eg, 0.13.). Answer: Suppose that the floating point component of a processor is upgraded so that each floating point instruction takes only 1/4 as much time to execute as previously. (The execution times of all other types of instructions remain unchanged.) If the upgrade decreases the execution time of a particular program to 0.7 times what it was originally, what fraction of the original execution time must have been spent on executing floating point instructions? (Give your answer as a decimal number to at most two decimal places, eg, 0.13.)
