15-745 Syllabus


Alfred V. Aho, Monica S. Lam, Ravi Sethi, and Jeffrey D. Ullman.
Compilers: Principles, Techniques, and Tools (2nd Edition).
Pearson Addison Wesley, 2006. ISBN: 978-0321486814.
(Note: It is important to use the 2nd Edition, rather than an earlier edition.)

This is a graduate-level course. If you need to brush up on the material covered in undergraduate-level compiler courses, please review the earlier chapters of this book and take a peek at the CMU undergrad compilers course: 15-411.


Your final grade for the course will be based on the following weights:

The project in 15-745 is an open-ended research project, done in groups of two (or three, with special permission). The project requires a proposal report, a milestone report, a final report, and a poster presentation.


Also available as an ical file that you can subscribe to.

Note: Class will meet on average two times per week, but we will frontload the lectures at the begining of the semester. This schedule is subject to change, so please hold all three days (Mon, Wed, Fri) open each week.
