15-849: Low-Power Computing


There are no required textbooks for the course. Depending on your background, you may find some of the following texts useful for references. In general, we assume that the average student taking this course is familiar with undergraduate operating systems, networks, and computer architecture concepts.

Possibly useful as references in your projects:


Your final grade for the course will be based on:

The midterms will be non-cumulative midterms, one in the middle and one towards the end of the semester.


This class is evolving rapidly; everything here, including the grading criteria, is subject to change.



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

Note: The schedule is (clearly) still evolving. For an unordered list of papers we'll be reading, see the course Wiki.
