- Processor R is a 64-bit RISC processor with a 2 GHz clock rate. The average instruction requires one cycle to complete, assuming zero wait state memory accesses. Processor C is a CISC processor with a 1.8 GHz clock rate. The average simple instruction requires one cycle to complete, assuming zero wait state memory accesses. The average complex instruction requires two cycles to complete, assuming zero wait state memory accesses. Processor R can’t directly implement the complex processing instructions of Processor C. Executing an equivalent set of simple instructions requires an average of three cycles to complete, assuming zero wait state memory accesses. Program S contains nothing but simple instructions. Program C executes 70% simple instructions and 30% complex instructions. Which processor will execute program S more quickly? Which processor will execute program C more quickly? At what percentage of complex instructions will the performance of the two processors be equal?A(n) ________________ instruction always alters the instruction execution sequence. A(n) ______________ instruction alters the instruction execution sequence only if a specified Condition is true.Will upvote!

- 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.On a uniprocessor, portion A of program P consumes 24 seconds, while portion B consumes 822 seconds. On a parallel computer, moderately serial portion A speeds up 4 times, while perfectly parallel portion B speeds up by the number of processors. 1- What is the speedup of program P on 1,024 processors? _______ times 2- How many processors are required to achieve at least half the theoretical maximum possible speedup on P?Consider the following portions of three different programs running at the same time on three processors in a symmetric multicore processor (SMP). Assume that before this code is run, Total is 15, val_1 is 45, val_2 is 25, and val_3 is 5. Core 1: Total = Total + val_1;Core 2: Total = Total - val_2;Core 3: Total = Total + val_3; 1. Show the assembly code for both instructions. Assume that Total, var_1, and var_2 are stored at 0x0100, 0x0120, and 0x0130 respectively.2. What are all the possible resulting values of Total? For each possibleoutcome, explain how we might arrive at those values. You will need to show all possible interleavings of instructions.3. How could you make the execution more deterministic so that only one set of values is possible?
- On an ARM processor, assuming that [N-bit] = 0, [Z-bit] = 0, [C-bit] = 1, [V-bit] = 1, predict whether each of the following branch instruction is going to make the flow of control branch to the instruction labeled by NEXT (i.e., YES or NO). (These instructions are NOT executed one after the other one; instead, each instruction starts with the initial conditions given in the statement.) (a) BLS NEXT (b) BNE NEXT (c) BLE NEXT (d) BVC NEXTThe 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.Suppose you have a computer that does instruction processing in anatomic way, with a clock cycle of 7ns and one instruction executioncompleted every cycle.You now split the processing into the five stages of the RISC pipeline,and you get required processing times of• IF: 1ns• ID: 1.5ns• EX: 1ns• MEM: 2ns• WB: 1.5nsYou now have added 0.1ns of delay between each of these stages. What’s the clock cycle time of this 5-stage pipelined machine?
- In the MIPS micro-architecture, the PC is incremented for each instruction, during the "Instruction Fetch" stage. The value of the PC may also be updated later within the "Memory Access" phase. * If the value of the PC is: 0x0000 2F1C, what is the value of the PC after you complete the execution of the instruction: ``addi $t0, $s0, $ra``?* <!-- response -->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.

Let the processor be a nice, simple RISC single-cycle machine. The instructions below are executed.
