Welcome to EECS 127/227A, Spring 2026!

Lecture recordings from Spring 2024 are available here. Lecture recordings from Fall 2022 are available here. They cover a lot of the course material, but neither set of material is a strict superset of the other.

Previous semesters’ staff have written a course reader (i.e., set of course notes), accessible here. This semester’s staff will periodically update and improve the reader.

Readings posted next to each lecture use the abbreviations:
