Course Description

This course is a graduate course on computer architecture with an emphasis on a quantitative approach to cost/performance design tradeoffs. The course covers the fundamentals of classical and modern processor design: performance and cost issues, instruction sets, pipelining, caches, physical memory, virtual memory, I/O superscalar and out-of-order instruction execution, speculative execution, long (SIMD) and short (multimedia) vector execution, multithreading, and an introduction to shared memory multiprocessors.


CIS501 is a graduate-level course on computer architecture that assumes significant prior knowledge of computer organization and architecture (do not be mislead by the word "Introduction" in the course title). You should already be familiar with hardware caches, instruction execution pipelines, basic logic design, and some assembly-level programming. Students will have expected to have had a course that covers the material in a textbook such as Patterson and Hennessy's "Computer Organization and Design: The Hardware/Software Interface". Penn's CIS371 is an example of such a course.

If you do not have the appropriate background, you should either consider not taking the course or spend significant time review this textbook and the lecture notes from CIS371.

Previous CIS501 Offerings

This course is based on my previous offerings of CIS501 over the last few years:


We will use the following textbook:

Those of you who feel that you are lacking in certain areas may also want to acquire a copy of the most recent edition of Patterson and Hennessy's "Computer Organization and Design: The Hardware/Software Interface".


  • Paper Reviews: 5%
  • Homework: 20%
  • Midterm exam: 30%
  • Final exam: 45%


There will be a midterm exam and a final exam. The final exam will be cumulative and will be held during the final time slot for the course. The final exam will also count as the PhD Architecture WPE I exam.


There will be several homework assignments, consisting of problems to be worked out by hand and/or coding of simulations. Homework is due at the beginning of the class period for which it is assigned. As for late homework, see the course overview slides for the specific policy.

Paper Reviews

We will read several papers from the research literature during this course. Before we discuss the paper in class, you will meet in groups to discuss the paper and write a concise response to a few high-level questions about the paper. To avoid the same groups for each paper, you may be in a group with a student at most once.

Academic Misconduct

Academic misconduct such as cheating will not be tolerated. The work you submit in this class is expected to be your own. If you submit work that has in part or in whole been copied from some published or unpublished source (including current or former students), or that has been prepared by someone other than you, or that in any way misrepresents somebody else's work as your own, you will face severe discipline by the university. (Adapted from text appearing at the Office of Student Conduct page.)

Any detected cases of cheating will be pursued. Penalties can include: receiving a zero on the assignment (the minimum penalty), failing the course, having a note placed in your permanent academic record, suspension, and ultimately expulsion.
