IC Questions 1. Consider three different processors P1, P2, and P3 executing the same instruction set P1 has a 3 GHz clock rate and a CPI of 15 P2 has a 2.5 GHz clock rate and a CPI of 1.0. P3 has a 4.0 GHz clock rate and has a CPI of 22 a. Which processor has the highest performance expressed in instructions per second instructions per second = clock_rate/CPI b. If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions, Number of cycles - cpu_time clock_rate Huber of instructions - number of_cycles/CPT c. We are trying to reduce the execution time by 30% but this leads to an increase of 20% in the CPI. What clock rate should we have to get this time reduction? Hints: See Slide 32-36 1 GHz 10 hertz CPI Cycles per Instruction 2. Assume a color display using 8 bits for each of the primary colors (red, green, blue) per pixel and a frame size of 3840*2160 (UHD-1 or standard 4k). a. What is the minimum size in bytes of the frame buffer to store a frame? b. How long would it tako, at a minimum for the frame to be sent over a 1000 Mbit/s network (Gigabit)
