- Suppose an instruction takes four cycles to execute in a nonpipelined CPU: one cycle to fetch the instruction, one cycle to decode the instruction, one cycle to perform the ALU operation, and one cycle to store the result. In a CPU with a four-stage pipeline, that instruction still takes four cycles to execute, so how can we say the pipeline speeds up the execution of the program?Assume that a lA32 computer has 8 execution stages and you want to execute a programwith 25 instructions. How fast a pipelined computer will execute the instructions than anon- pipelined computer?Is it still feasible to accomplish pipelined execution even if the time it takes to execute pipeline instructions is not balanced? Where can you perceive the inefficiencies in this situation?
- A hypothetical processor has 9 stages of a pipeline as shown in the table below. The first row in the table below shows the pipeline stage number, second row gives the name of each stage, and third row gives the delay of each stage in Nano-seconds. The name of each stage describes the task performed by it. Each stage takes 1 cycle to execute. This processor stores all the register contents in a compressed fashion. After fetching the operands the operands are first decompressed, and before saving the results in register file, the results are first compressed. a)How many cycles are required to execute one instruction on this pipeline? b)How many cycles are required to execute 19 instructions on this pipeline? Assume that no stall cycles occur during the execution of all instructions. c) Assume that all necessary bypass/forwarding circuitry is implemented in this 9 stage pipeline. How many cycles will the pipeline stall during the execution of below given two instructions? Briefly explain…Yes, even if pipeline instructions take a different amount of time to execute at different times. Where can the problems with this situation be found?If the execution times of the pipeline instructions are not balanced, is pipelined execution still possible? Where do you see the inefficiencies here?
- Can pipelined execution be attained if the times at which individual pipeline instructions run are not equal? Exactly what inefficiency have you noticed?Assume a 3GHz processor executes three classes of instructions(A, B, C).i. Calculate the average CPI for this sequence of program.ii. Calculate the execution time for this sequence of program.iii. If we use a system with four same processors, there will bespeed up by a factor of 4 for classes A and C, but class B willremain unaffected. Calculate the new execution time for thissystem. What is the overall speed up? Class A B C CPI for class 4 2 10 IC in sequence 100 200 300On a modern pipelined computer, how can a computer programme be optimised so that it runs rapidly and consumes little energy?
- What is pipelining in computer architecture, and how does it improve CPU performance? Provide a basic diagram to illustrate a 5-stage pipeline.An operation is considered to have been successfully stopped when the central processing unit (CPU) accepts the interruption and proceeds on to the next job. If the process is already underway, then why is it impossible to halt it? Since the execution and cleaning can wait till we've resolved the problem, there's no reason not to take care of them right now.Suppose that a microprocessor operates at 5MHz. How long does the bus cycle occupy, assuming no wait states are inserted?
