Develop a program consisting of primitive CPU instructions to implement the following procedure: integer i,a; i = 0; while (i 10) do a = i2; i = i + 1; endwhile
Suppose the implementation of an instruction set architecture uses three classes of instructions, which are called A, B, and C. The total dynamic instruction count is 1 x 10^7 and the processor's clock rate is 2.5 GHz. Details for the three classes are given in the table below: Class CPI % of instructions A 1 20% 50% C 3 30% Complete the following table. Express all answers in scientific notation and round to two decimal places, when needed. Class Instruction Count Number of Clock Cycles х 10^ x 10^ A х 10^ х 10^ x 10^ х 10^ C
The inquiry is phrased as follows: "Are you able to offer an overview of CPU scheduling strategies?"
Q3) b There are two implementations; computer “A” with 1.75 GHz processor and 512 MB of RAM, while the processor speed of computer “B” is two times faster than A, i.e. 3.5GHz and similarly 1 GB of RAM. There is program with 10 instruction runs on A in 20ns while in the same period of time the another program with 20 instructions runs on B. Determine the CPUs performance and decide which one is faster.

What measures may be taken to ensure that a CPU's processing cycles are not needlessly squandered while it attempts to handle a huge number of instructions all at once? Can you tell me how much the presence or absence of specific elements affects the viability of this plan? Give an example of one of the results they generate.
Follow this steps. Have to Consider two different implementations, M1 and M2, of the same instruction set. There arethree classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 2.0GHz and M2has a clock rate of 2.5GHz. The average number of cycles for each instruction class and their frequencies(for a typical program) are as follows:Instruction Class M1-Cycles/InstructionClass M2 -Cycles/InstructionClasss FrequencyA 1 2 60%B 3 2 30%C 4 3 10%(a) Calculate the average CPI for each machine, M1, and M2.(b) Calculate the average MIPS ratings for each machine, M1 and M2.(c) Which machine has a smaller MIPS rating? Which individual instruction class CPI do you needto change, and by how much, to have this machine have the same or better performance as themachine with the higher MIPS rating (you can only change the CPI for one of the instructionclasses on the slower machine)?.

Assume for a given program, 60% of the executed instructionsare of Class A, 10% are of Class B, and 30% are of Class C. Furthermore,assume that an instruction in Class A requires 3 cycles, an instruction inClass B requires 2 cycles, and an instruction in Class C requires 2 tocomplete. i. Compute the overall CPI for this program.ii. Compute the clock rate of the CPU when the time it takes tocomplete 20 instructions is 1.73 ???????????
Convert the given code fragment to assembly code fragment, using only instructions of the following types. These instructions are generally discussed in class. Here X,Y,Z are any memory locations; R, R1, R2 are any general registers; L is a label in the code (you can use any names as labels, ex. L, L1, L2 etc. ). load X, R //copy contents of memory location X into R. store R, X //Store contents of R into Mem location X cmp R1, R2 //Compute R1-R2 and update condition codes; //throw away result of subtraction. jmp L //Jump to location L in the code. jmpp L //If P bit is 1, Jump to location L in the code add X, R //Add contents of X,R and store result in R; //Also update the condition codes. Be careful about what type of argument is allowed in the instruction (Memory or Register). Ex. the first argument of ADD instruction is memory, not register. Do Not…
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. Wehave a particular program we wish to run. When compiled for computer A, thisprogram has exactly 100,000 instructions. How many instructions would theprogram need to have when compiled for Computer B, in order for the twocomputers to have exactly the same execution time for this program?
