Question 1

A non-pipelined CPU with a clock frequency of 2 GHz has instruction latencies with relative frequencies of instructions as shown in the following table.

 

Instruction Type Instruction Latency Relative Frequency
Loads 5 30%
Stores 4 15%
Branches 3 10%
Jumps 2 5%
ALU/Logic 4 40%

 

  1. Calculate the average CPI.
  2. Calculate the average instruction execution time (IET).

A pipelined version of the CPU adds 0.1 ns overhead.

  1. Calculate the average instruction execution time of the pipelined CPU.
  2. Calculate the speedup obtained with the pipelined CPU.

Question 2

Consider the code sequence shown in the box on the right. Each instruction is numbered for reference (I1 – I7).  Assume execution on a 5-stage pipeline.

 

  1. Make a list of the RAW (read after write) data hazards in the code sequence.  Using the reference numbers, your list should state the two instructions associated with the hazard and the register on which the hazard exists.
  2. In your list of hazards, place an asterisk (*) in front of those that are resolved by data forwarding.
  3. Place a hash (#) mark in front of any hazards not resolved by data forwarding. If any exist, determine if the hazards can be resolved by reordering the code sequence and show the new sequence.

 

Question 3

The basic formula for calculating AMAT is

The time for a hit is equal to the hit rate * cache access (hit) time.  Recall the miss rate is

1 – hit rate.

For a 2-level cache, the AMAT formula is expanded to

The following table defines the profile for a multilevel cache hierarchy with main memory.

 

Memory Level Hit Time Hit Rate
L1 Cache 0.5 ns 80%
L2 Cache 1.8 ns 95%
L3 Cache 4.2 ns 98.5%
Main Memory 70 ns 100%

 

Misses in all three levels of cache will eventually hit in the main memory.

  1. Derive the formula to calculate the AMAT for this multilevel cache design.
  2. Using the information in the table and the derived formula, calculate the average memory access time for this memory hierarchy.

 

Question 4

Using the code sequence in Question 2, create a pipeline diagram that shows the execution of the instructions by cycle.  Example:

Be sure to indicate any stalls due to unresolved hazards if any exist.

How many cycles are required for the code to execute in the pipeline?

ENGL 112: ARGUMENT ANALYSIS WORKSHEET

Instructions: Find an article online about a topic that interests you. You may use a database from our library that’s provided on the course page, or you may use an online search engine. The Opposing Viewpoints database would be the easiest and most reliable for this type of assignment. That particular database would also give you great ideas for research paper topics.

Read your chosen article closely and answer ALL of the following questions to the best of your ability. Think of each assignment as practice. The more you do, the more prepared you’ll be for doing research and to write your own paper.

NOTE: These are not essay assignments. You only need to answer each question.

  1. What is the issue (the main topic)?
  2. What is the argument (writer’s position on the main topic)?
  3. Identify and provide the one sentence you think is the writer’s main claim.
  4. What reasons does the writer give to support the main claim (HINT: Examine the topic sentence—first sentence—of each body paragraph).
  5. What kind of evidence does the writer provide to support the claim?
  6. What counter argument(s), if any, does the author mention? A counter argument identifies a position opposite that of the writer and explains why that opposing view is flawed.
  7. Did the author influence your thinking about the argument? Why or why not?
  8. What is your position on the topic and what reasons do you have for your position?
  9. Create an APA reference entry for the article (use the library APA link for help).

Scenario 1: You’re working on a VR title and a new gun was introduced into the game. The gun has unlimited ammo and only one skin. Write at least five test cases for how you would test the gun.

Scenario 2: You are the client that joins another tester who is the host. The client and host shoot at the same enemy. The host stops shooting and moves on to another enemy. You keep shooting but the enemy keeps walking and does not seem to take damage. The host does not see this issue. What do you do? How would you write a bug for this?

Scenario 3: You are working with 7 other testers to test an 8-player multiplayer game. There is a lobby players can join in on before a game will start. Players can: search for a game, be invited to a match, join a friend’s lobby, join mid-game, or create a private match. What are some tests you would do? How would you communicate them to the team?

What are dimensions of a product quality? How the quality of the Product can be improved? Discuss its cycle. What are different types of Quality through which customer satisfaction and fitness for use can be ensured?

/in /by

Quality

Quality plays a very vital and important role in any project whether it be a manufacturing or service industry not only to increase market share but also to avoid accidents. At its simplest, quality means meeting the intended purpose. Quality is also known as ‘fit for use.’ Quality products meet the stated requirements, have tolerable levels of defects, and are consistently produced. In short, quality means accurate (correct) and precise (consistent) results within a project.

Quality improvement is the framework used to systematically improve care. Quality improvement seeks to standardize processes and structure to reduce variation, achieve predictable results, and improve outcomes for patients, healthcare systems, and organizations.

Q1. What are dimensions of a product quality?   (5 Marks)

Q2 How the quality of the Product can be improved? Discuss its cycle.    (5 Marks)
