Q4. (20 points) Consider the following sequence of instructions being processed on the 5-stage RISC-V pipelined processor: lw r4, 100 (r2) add r5, r2, r3 sub r6, r4, r5 and r7, r2, r5 I. Identify all the data dependencies in the above instruction sequence. For each dependency, indicate the two instructions and the register that causes the dependency. I Assume that the pipelined uses full forwarding. Draw a pipelined diagram that represents the flow of instructions through the pipeline during...
I just need part (d) answered
7) [24 marks] Consider the following MIPS code segment that is executed on a 5-stage pipeline architecture that does not implement forwarding or stalling in hardware. (1) add $4, $1, $1 (2) add $7, $4, $9 (3) lw $2, 400S8) (4) sub $8, $1, $2 (5) SKSs, so($2) (6) sub $2, $8, $4 (7) lw $3, 2($1) (8) add $8, $4, $2 Identify the data dependences that cause hazards. You are to use the...
These two pieces of code are executed on a 5 stage pipelined processor. Code-A : Counting sum of 1 to 100 using a for loop . Code-B : Looping through 100 values and printing if values are +ve or -ve. There is 50-50 chance of value being positive or negative. This processor always predicts 'branch is taken'. Which code does suffer more from purging / aborting instruction on fly? a) Both will suffer equal b) Insufficient information c) Code A ...
Investment companies and performance evaluation 1) Consider two different hedge funds with the following data related to performance: Hedge fund Alpha Beta Fund A 5% 1.6 Fund B 3% 0.8 Assuming that beta is consistent with the type of investing we expected in both cases, which fund performed better. A. Fund A, because it had the higher return B. Fund A, because it had the higher alpha C. Fund B, because its alpha is more impressive than Fund A when...
2. (b) Alkenes are stabilized by alkyl substituents through hyperconjugation. Briefly (one or two typed lines), in the space below, describe how this stabilization works:
Problem 2: Consider two alternative simulation models with the following notation: 0,: mean performance measure of alternative l 2: mean performance measure of alternative 2 Yr1:average of the performance measure of alternative I observed during the rh replication for r-1,2,..., R2 From running two models, the data in the table below is obtained. Yzi average of the performanee measure of alternative 2 observed during the fh replication for rl 4 10 14 Answer the following questions: Calculate the sample average...
If a company’s control risk is initially assessed as low, the auditor needs to gather evidence on the operating effectiveness of the controls. For each of the following control activities listed as (1)–(10), do the following two tasks: a. Describe the test of control that the auditor would use to determine the operating effectiveness of the control. b. Briefly describe how substantive tests of account balances should be modified if the auditor finds that the control is not working as...
Management in Action CONTROL SYSTEMS AT FACEBOOK Controlling performance at Facebook takes many forms. One is Mark Zuckerberg's creation of new partnerships with third-party companies like Nielsen and comScore to ensure that his company reports accurate data about users' responses to advertising, such as the average time they spend looking at videos. These data helps advertisers decide where and how to spend their ad dollars, based on the ads' measured effectiveness. Some data reported in the fall of 2016 were...
The vice president of operations of Recycling Industries is evaluating the performance of two divisions organized as investment centers. Invested assets and condensed income statement data for the past year for each division are as follows: Business Division Consumer Division Sales $2,200,000 $2,490,000 Cost of goods sold 1,260,000 1,335,000 Operating expenses 698,000 831,300 Invested assets 1,100,000 2,490,000 1. Prepare condensed divisional income statements for the year ended December 31, 20Y8, assuming that there were no service department charges. Recycling Industries...
5.) (1 point) Ms. Marvel detects two gigantic asteroids traveling through space which will collide and send them on a trajectory to destroy the Earth. When they collide, she calculates that the 3-component vector describing the direction of their impact force are: 3 a = 1-51 12.5) -- and a2 = 2 11.25) Her plan is to blast the asteroids at the point where they meet to cause them both to remain absolutely still. What vector will describe the force...
