The final exam is cumulative.  Thus, it covers all the lectures, labs,
homeworks, and software assignments.

The new material since Exam 2 is the material on control.  Focus on
the lecture notes and labs since the exam for this new material. 

At the exam, you will be given: the green card, C.5.10 (the individual
ALUs) and C.5.12 (the fullest N-bit ALU, the one that also handles
BEQ), the final single-cycle control diagram (the handout with Lab 13;
Lecture Notes Chapter 4, Part 2, Slide 19); the Control Unit Design
circuit figures (Lecture Notes Chapter 4, Part 2, Slide 16); and the
final multi-cycle control diagram (the handout with Lab 14; Lecture
Notes Multi-Cycle Control, Slide 39).
