Multiple choice (Select the best answer), Truel False : 1. What is the best way to measure the performance of a system : A) Use a benchmark program. B) Use any random program and measure the execution time C) Use the clock rate frequency Mhz as the measure (D) Use the MIPs measure. 2. What is the CPU execution time for an instruction that takes 7 clock cycles on a 1khz processor A) 142.85sec B) 0.07s C) 7000s D) 0.007s 3. What is the CPU execution time for the following program on a 100hz processor. The program has 400 instructions that are executed. Each instruction has a CPI of 2. A) 20,000s B) 0.5s C) 0.0000125s D) 8s 4. The Instruction execution rate MIPS is one of the best measures of performance. T/F 5. For a given ISA, performance improvements come from : A) Increases in clock rate (without increasing the CPI) B) Increases in both clock rate and CPI C) Decreases in both clock rate and CPI
