- Suppose without pipelining, a processor takes 100sec to complete execution of 05 instructions, assuming each instruction require same amount of time for execution. If we can have 5 stage ideal pipeline for the same processor, then How much time will it take to complete execution of these 05 instructions? How much speedup we can achieve?Consider three different processors P1, P2, and P3 executing the same instructionset. P1 has a 3GHz clock rate and a CPI of 1.5. P2 has a 2.5GHz clock rate and a CPI of 1.0, P3has a 4GHz and a CPI of 2.5.a) Which processor has the highest performance expressed in instructions per second?b) If the processors each execute a program in 5 seconds, find the number of cycles and thenumber of instructions.c) We are trying to reduce the execution time by 20% but this leads to an increase of 15% inthe CPI. What clock rate should we have to get this time reduction?Let's assume that there are three processors, Pa, Pb, and Pc, like below. You can assume 1-way superscalar, no hyper-threading, and no pipelined for all processors. Pa: 4 GHz clock rate, CPI: 2.2 Pb: 3 GHz clock rate, CPI: 1.5 Pc: 2.5GHz clock rate, CPI: 1.05.1. Show each processors' performance in terms of instruction per second.
- Assuming the clock periods for two pipelined machines are as follows: Machine 1 without forwarding: 300ps Machine 2 with forwarding: 400ps What is the total execution time of this instruction sequence on Machine 1 and Machine 2?Consider three different processors P1, P2, and P3 executing the same instruction set. P1 has a 3 GHz clock rate and a CPI of 1.5. 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 2.2. Which processor has the highest performance expressed in instructions per second? If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions.consider a CPU that implements two parallel fetch-execute pipelines for superscalar processing. Show the performance improvement over scalar pipeline processing and no-pipeline processing, assuming an instruction cycle similar to figure 4.1 in the Section I B of "Advanced Systems Concepts", i.e.: a one clock cycle fetch a two clock cycle decode a three clock cycle execute and a 200 instruction sequence: Show your work. 7. o pipelining would require _____ clock cycles: 8. A scalar pipeline would require _____ clock cycles: How high is the increase in speed (percentage) compared to no pipelining? 9. A superscalar pipeline with two parallel units would require ______ clock cycles: How high is the increase in speed (percentage) compared to no pipelining?
- A non pipelined processor has a clock cycle of 8.0 ns to execute each instruction. If a 6-stages pipeline is implemented, with an overhead of 0.06 ns per stage, the new clock cycle should be?Question: Suppose a program of 600 instructions runs on a 2 GHz processor. The frequency of instructions and the clock cycle counts per instruction are given as follows. What is the average CPI of this instruction mix? Operation Frequency Clock Cycles ALU operations 55% 1 Loads/Stores 30% 2 Branches 15% 3 Question: Continue from the previous question. What is the CPU time of the program in nanoseconds? Question: Suppose a processor P has a 2.5 GHz clock rate and a CPI of 1.5. If the processor executes a program in 3 microseconds, find the number of instructions in the program.Consider two processors P1 and P2. P1 has a clock rate of 2 GHz, average CPI of 0.8, and requires the execution of 5.0 x 10^9 instructions for a given task. P2 has a clock rate of 3 GHz, an average CPI of 1.2, and requires the execution of 6.0 x 10^9 instructions for the same task. Does the processor with the highest clock rate have a better performance? Justify your answer.
- Suppose on a non-pipelined single-processor machine, you have the following breakdown: alu instructions make up 25% of the dynamic instruction count, and take 2 cycles to execute. Load/store instructions take 10 cycles to execute and make up 30% of the mix. Jumps take 4 cycles and make up 15%. All other instructions average 1.5 cycles. a. What is the average CPI? b. Suppose the architecture above is pipelined. If there are no stalls for any reason, what is the new CPI? c. If, for the architecture described in questions a and b, Load/store instructions generate 2 stalls on average, alu 0.2 stalls, and jumps cause 1 stall, what is the actual pipelined cpi?The runtimes of the five stages of executing an instruction in a non-pipelined machine are listed below. Instruction Fetch 100ps Instruction Decode 200ps ALU 300ps Memory 300ps Write Back 200ps This is then converted into a pipelined machine M1 using the most critical stage as the cycle time. For a new machine M2, we are allowed to break up exactly one stage into two substages of equal times giving us a six stage pipeline. A1: Discuss in short clear sentences the latency differences between the machines M1 and M2. A2: Discuss in short clear sentences the throughput differences between the machines M1 and M2.Q: Consider three different processors P1, P2, and P3 that support the same instruction set. P1 has a 3 GHz clock rate and a CPI of 1.5. 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 2.2. (a) Which processor has the highest performance expressed in instructions per second? Show your calculations. (b) If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions for each processor. (c) We are trying to reduce the execution time by 30% (i.e., execution time is reduced from 10 seconds to 7 seconds). However, this leads to an increase of 20% in the CPI. For each processor, what clock rate should we have to get this time reduction? (Show the calculations you did to answer this question.)
