Suppose a computer M3 has an average CPI of 2.7 and a clock rate of 3.7 GHz. Please answer the following: (a) Calculate the runtime for a program P with 22,933 instructions, which uses an accelerating co-processor 45 percent of the time, and (b) determine how much faster (or slower) the accelerator needs to run for P to run 1.5 times as fast on M3 with the faster (resp. slower) accelerator.

Suppose a computer M3 has an average CPI of 2.7 and a clock rate of 3.7 GHz. Please answer the following: (a) Calculate the runtime for a program P with 22,933 instructions, which uses an accelerating co-processor 45 percent of the time. (b) determine how much faster (or slower) the accelerator needs to run for P to run 1.5 times (1.5X) as fast on M3 with the faster (resp. slower) accelerator. Hint: First set up your equation for Amdahl’s Law,...
Problem 1 Assume that a processor with a clock rate of 1 GHz clock runs a benchmark program w mix of instructions given in the table below. Instruction class CPI FP INT Load/Store (L/S) Branch Instruction count 50 x 106 110 x 106 50 x 106 10 x 106 By how much must the CPI of L/S instructions be improved if the program is to run two times faster?
5. If a processor clock ticks 4 billion times in a second and has a frequency of 1.5 GHz, with each clock tick, one or more instructions may complete, if a program runs on 3 GHz processor for 7 seconds, how many clock cycles did it run for? (10 points) If a program runs for 2 billion clock cycles on a 1.5 GHz processor, what is the execution time in seconds? (10 points)
Computer A executes the MIPS ISA and computer B executes the x86 ISA. On average, programs execute 1.5 times as many MIPS instructions as x86 instructions. Computer A has an average CPI of 1.5 and computer B an average CPI of 3. If computer B runs at a 3GHz clock frequency, what speed does computer A have to run at to be at least as fast as computer B?
About computer architecture and organization. Please solve those questions Thank you 2. A certain program has the following instruction classes, CPIs, and mixtures: Instruction Type CPI ratio 1.5 .40 2.1 .35 3 a. What is the average CPI for this processor? b. You have the following options: • Option 1: Reduce the CPI of instruction type B to 1.8 • Option 2: Reduce the CPI of instruction type C to 2.5 Which option would you choose and why? 3. Consider...
(6 pts) A program P2 is executed on computer system B, which has a 2.8571429 GHz clock frequency. A programmer writes code to read processor performance monitoring registers after the program completes (Intel refers to the part of the CPU that can be used to collect run-time information as the Performance Monitoring Unit or PMU). The performance monitoring unit indicates that 23,118,471,971 user instructions were executed (just the instructions of P2 excluding OS and overhead instructions) in 53,866,039,692 clock cycles....
Suppose we have developed new versions of a processor with the following characteristics: Version Voltage 1.5 V 1.2V Clock rate 2.4 GHz 3GHZ a) How much has the capacitive load varied between versions if the dynamic power has been reduced by 15%? Assuming that the capacitive load of version 2 is 70% the capacitive load of version 1, find the new voltage value for version 2 if the dynamic power of version 2 is reduced by 35% from version 1....
Question : Suppose a typical program has an instruction mix of 40%, 15%, 20%, and 25% for instruction types A, B, C, and D respectively. On processor P1, the CPIs for these instruction types are 1, 2, 3, and 4 respectively, and the clock rate is 2GHz. One representative program, S, executes 1 million instructions. (a). Processor P2 has the same ISA but needs 2 CPI for all instruction types. What clock rate would P2 need to have the same...
