Midterm Policies

The midterm will be a 72-hour take-home exam, though it is only intended to take you 1 - 4 hours. You will be given the entire window to work on the exam.

The exam will be run via question prompts in Gradescope and may involve using computational artifacts (i.e., text, source, assembly, and executable files) on a computer terminal. Responses are submitted via Gradescope.

You will be allowed to ask clarifying questions about the exam to the course staff on Ed Discussion and in office hours. We want to make sure that you are interpreting the questions correctly and not answering the wrong questions, but we cannot help you with the process of solving the exam questions. The exams are open book/notes (e.g., website, book, readings, lecture notes, recordings, attu, CSE VM, midterm reference sheet).

The only discussion allowed is with classmates following the "The Gilligan's Island Rule". Writing on a board or shared piece of paper during the meeting is acceptable; however, you should not take any written (electronic or otherwise) record away from the meeting. Everything that you derive from the collaboration should be in your head. After the meeting, engage in at least a half-hour of mind-numbing activity (like watching an episode of Gilligan's Island), before starting to work on the assignment. This will assure that you are able to reconstruct what you learned from the meeting, by yourself, using your own brain and should prevent your written answers from being too similar to one another's. In all other cases, discussion with other people, including online forums, message boards, and "homework help" sites is prohibited.

Midterm Topics

Memory, Data, and Addressing: pointers, endianness, data sizes, bitwise operators

Number Representation: binary, integers, floating point

x86-64 Topics: registers, instructions, control flow

Procedures and the Stack: stack structure, calling conventions, register conventions, recursion

Building an Executable: compiling, linking, loading

Some of the old exams may contain questions on topics that we did not cover before the midterm this quarter; you should skip over such questions.
