  • Consider the tradeoffs in designing a modern instruction set architecture.

  • Understand how parallelism is applied in modern processors, including pipelining, superscalar design, vector and VLIW instructions, multicore processors, and cache coherency.

  • Analyze numerical measurements of computing performance, applying them to choosing between computing system designs.


I recommend Computer Architecture: A Quantitative Approach, 5th edition by John Hennessy and David Patterson, published by Morgan Kaufmann, 2012. (This edition is reorganized extensively from previous editions, and it is much better.)

This book is not necessary for your success in this course: I will not assign readings or exercises from the book. However, I will not have extensive on-line course notes as in some other courses. Instead, lectures will roughly follow the book, and the Web page's course schedule will include cross-references to this book. The book is well-written, and it provides far deeper information than we can reasonably discuss; reading it as we go through the semester would be worthwhile.

(Please note that the first chapter is freely available (also on Kindle), so you can use it to decide whether to invest in the rest.)

There are a total of 1,000 points over the semester. Letter grades will be assigned with cutoffs at 900 for an A, 800 for B, 700 for C, and 600 for D.

Class attendance/participation 60 pts
Assignments 490 pts
Tests (two, 140 pts each) 280 pts
Final 170 pts
TOTAL 1,000 pts

I reserve the right to make adjustments in the entire grading scheme or in particular cases.

While I do not have a specific goal about the assigned grades, the grades I assign tend to average around 3.0. Note that I do not normally “curve” grades at the end of the course; instead, I monitor your progress and perform any “curves” as I grade tests. When I “curve” test scores, I add a fixed amount to all scores; as a result, some test scores may end up being above 100%. I anticipate, but will not insist, that the median test score will be around 75%. Normally, scores in the non-test categories will be higher; the average class grade will likely be a B even though the average test grade is a C.


Several points are designated for “class participation.” I will assign half of these points near the semester's middle, and the other half near the semester's end.

I do monitor your class attendance. If your attendance is excellent (missing one or fewer classes each half-semester), you will receive at least 60% of these attendance/participation points. If you feel your absence should be excused, please warn me about the absence a day in advance. Whether I excuse your absence is my call.

The remaining 40% of these points are for participation, including both questions during class and responses to questions during class. I may give more than full credit in unusual circumstances. Take this as an invitation: I value your active participation in class, and I expect you to show evidence of being fully tuned in during class sessions.


You will often have assignments. Unless otherwise specified, you should feel free to work alone or with one other student. If you work with somebody else, you should jointly submit a single solution. I reserve the right to change this policy, individually or collectively, at any time.

You may also ask occassional questions of classmates when you need help. Under no circumstances should I receive two copies of identical or near-identical solutions.

You will be given at least a week to complete each assignment, and they will normally be due at 5pm on Thursdays. For each 24-hour period from the time due, I will deduct up to 10% of the points possible.


The scheduled days for tests, listed below, will likely not change.

Tests will last 75 minutes. The final will be 120 minutes long.

If you miss a test, you must receive advance permission from me to receive more than a 0. (Dire medical emergencies usually constitute an exception.) If you are excused from the test, I will either double your lowest quiz or exam score or administer a make-up, at my discretion. Let me know well in advance — 24 hours for exams and quizzes, and two weeks for the final. I would like to remind you that, when e-mail is impossible, telephones exist also. Do not skip a test without my prior approval!

Note that I may require you to document your reason for absence. Travel arrangements and work schedules are not adequate reasons to miss a test.


Any instances of academic dishonesty (plagiarism, cheating on exams or quizzes, submitting work that is not fully your own, etc.) will be reported to the Academic Integrity Committee. For details on the procedures involved with academic dishonesty issues please refer to the Hendrix catalog.

You must properly attribute any work or ideas you use in assignments for this course which are quoted or derived from others. Plagiarism includes not only copying the ideas and the written and spoken words of others, but also copying or otherwise appropriating their computer files as well. Interfering with the work of others is also a serious academic offense.

Discussing or viewing others' solutions to assignments is officially out of bounds, as is discussing or showing your own solution to others. In practice, I realize, you may help other students; this presents a problem only when the solution you submit is substantially similar to another student's. A strong correlation between your solution and a classmate's solution constitutes evidence of cheating.

Office hours

Feel free to stop by my office any time you want to talk about something related to the class. I do have “office hours” listed on the Web page, but they are not intended to limit you. The office hours represent when I will try to be available in my office, but I'm equally available at all times that my office door is open. I'm also happy to arrange appointments.

If you're not in the building, feel free to telephone my office. And if I'm not in my office, you can send e-mail. But please try to contact me directly before e-mail: E-mail is much less efficient.


Most Hendrix students intuitively know the appropriate bounds for behavior in class. But: Cellphone use is prohibited during class, even for text-message or leaving the classroom to receive calls. Use of laptops is allowed, but only for activities related directly to what is currently being discussed; I reserve the right to prohibit them if I feel this policy is being abused.

Any inappropriate use of electronic devices (or of reading materials) is worse than an absence, since it distracts other students. It will count accordingly in the attendance/participation policy; you could potentially receive a negative score.

On tests, no electronic devices other than a simple watch are permitted.


It is the policy of Hendrix College to accommodate students with disabilities, pursuant to federal and state law. Any student who needs accommodation in relation to a recognized disability should inform the instructor at the beginning of the course. In order to receive accommodations, students with disabilities are directed to contact Julie Brown in Academic Support Services at 501–505–2954.
