- Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600MHz. Computer B has a CPI of 2.5 and can be run at a clock rate of 750 MHz. We have a particular program we wish to run. When compiled for computer A, this program has exactly 100,000 instructions. How many instructions would the program need to have when compiled for Computer B, in order for the two computers to have exactly the same execution time for this program? Please explain how to solveTwo computers have 8-stage fetch-execute cycles where branches are determined in stage 4.One computer is not pipelined, and the other is pipelined. Assuming that tp = 1, answer thefollowing questions when running a program with 50,000 instructions where 4,000 of theinstructions are conditional branches and each branch, if taken, skips over 5 instructions.a.

Suppose a program for a racing drone consists of a purely sequential part which takes 25 cycles to execute, and an iterated loop which takes 100 cycles per iteration. independent and cannot be further parallelized. If the loop is to be executed 100 times, what is the maximum speedup possible using an infinite number of processors (compared to a single processor)? Assume the loop iterations areTwo algorithms A and B report time complexities expressed by the functions n2and 2n, respectively. They are to be executed on a machine M that consumes 10–6 sto execute an instruction. What is the time taken by the algorithms to complete theirexecution on machine A for an input size of 50? If another machine N that is 10times faster than machine M is provided for the execution, what is the largest inputsize that can be handled by the two algorithms on machine N? What are yourobservations?Suppose a program segment consists of a purely sequential part which takes 100 cycles to execute, and an iterated loop which takes 400 cycles per iteration. Assume that the loop is dependent on the sequential part, i.e., both parts cannot run in parallel. Also assume that the loop iterations are independent, and cannot be further parallelized. If the loop is to be executed 100 times, what is the maximum speedup possible using an infinite number of processors (as many processors as you could possibly need) compared to a single processor?
- The runtimes of the five stages of executing an instruction in a non-pipelined machine are listed below. Instruction Fetch 100ps Instruction Decode 200ps 300ps 300ps ALU Memory 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.

- In a timesharing OS we have the following cpu timeline for two tasks X and Y. The timeslice is 1s.Both tasks are available in the system at the same time t=9:00:00.000 and order of arrival is the obviousX followed by Y. (The decimals reflect milliseconds if they showup in an indicated time reference.) There are no other processes (tasks) in the system other than X,Y. 1234567890 XYXYX--YXY The time line 1 indicates that at t=9:00:00s task X starts its execution and when t=9:00:01s is reached task Y takes over. The time line 1 indicates the 'first second' and time line 0 indicates the 'tenth second' above.Task Y completes its execution at t=9:00:10s, the completion of the tenth second since X started its execution. Task X has completed its execution earlier.
