- 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.Consider a 32-bit computer with the MIPS assembly set, that executes the following code fragment loaded in memory in the address 0x0000000. li $t0, 1000 li $t1, 0 li $t2, 0 loop: addi $t1, $t1, 1 addi $t2, $t2, 4 beq $t1, $t0, loop This computer has a 4-way associative cache memory of 32 KB and lines of 16 bytes. Calculate the number of cache miss of the previous code, and the hit ratio, assuming that no other program is executing and that the cache memory is initially empty.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.

The scheduler has not done any juxtaposing of the commands. a. There will be no hazard situation as the load word deals with the data memory and the read is from the registers. b. There will be no hazard situation, since the read is from the same location where the write is taking place. c. It is possible to avoid a bubble in the flow by forwarding from the write back stage. d. It is not possible to avoid Data Hazard issues here and inserting a bubble is a way out of this issue.
- In this exercise, we examine how pipelining affects the clock cycle time of the processor. Problems in this exercise assume that individual stages of the datapath have the following latencies: IF ID EX MEM WB 270 ps 150 ps 240 ps 290 ps 180 ps Also, assume that instructions executed by the processor are broken down as follows: alu beq lw sw 40% 15% 35% 10% 3.0.1 What is the clock cycle time in a pipelined and non-pipelined processor? 3.0.2 Assuming there are no stalls or hazards, what is the utilization of the data memory? 3.0.3 Instead of a single-cycle organization, we can use a multi-cycle organization where each instruction takes multiple cycles but one instruction finishes before another instruction is fetched. In this organization, an instruction only goes through stages it actually needs (e.g. ST only takes 4 cycles because it does not need the WB stage). Compare clock cycle times and execution times with…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?1. Consider the operation of a machine with the data path of the figure below. Let us call thismachine "Teletraan-1". Teletraan-1 has no pipeline. Suppose that fetching an instruction takes4 nsec, decoding an instruction takes 1 nsec, fetching the operands from memory or registersto ALU takes 2 nsec, running the ALU takes 2 nsec, storing the result back to the destinationregisters takes 1 nsec.How much time does Teletraan-1 need to execute 1 million instructions?A. 1 nsec x 1 million = 0.001 secondB. 2 nsec x 1 million = 0.002 secondC. 4 nsec x 1 million = 0.004 secondD. 10 nsec x 1 million = 0.01 second 2. Since the above machine Teletraan-1 has no pipeline, an instruction must be completed in oneCPU clock cycle. As a result, a CPU clock cycle must be longer than or equal to the executiontime of one instruction. To improve it, we developed "Teletraan-2". Teletraan-2 has a fivestage pipeline. It takes 5 nsec to fetch an instruction, 2 nsec to decode an instruction, 3 nsec tofetch…

For each possible outcome, explain how we might arrive at those values. You will need to show all possible interleavings of instructions. c) How could you make the execution more deterministic so that only one set of values is possible?In this exercise, we examine how pipelining aff ects the clock cycle time of the processor.
