Overview

Prerequisites

Course Description

You know how to program, but do you know what is going on behind the scenes to make the computer work? This course is designed to give you an introductory understanding of how your computer works as a physical device that executes lines of code. To do this, we will start with transistors and build up to gates, memory, a simple processor and assembly instructions. In the second half of the course we will explore C, a low-level programming language, and how it is translated into assembly instructions.

After completing this course, you should have knowledge in C and computer architecture that will provide a solid foundation for future courses relating to systems. Some of these courses include CIS 4710 (Computer Organization and Design), CIS 3800 (Computer Operating Systems), CIS 1900 (C++ Programming), CIS 3410 (Compilers), and many other courses.

Course Materials

Virtual Machine

For this course, we will be providing a Virtual Machine for you to complete your homework. We strongly recommend that you work on any coding assignments in this same environment. Assignments will be graded in an environment where as close to the virtual machine as possible, and behavior of low-level programs can change based on the environment it is run in. You are responsible for making sure that the programs you write work in the provided environment.

Website

The website acts as the central place for organizing material for the course. All essential material for the course is delivered through or linked through the course website. As an example, the website contains the course schedule, lecture materials, recitation materials, homework specifications, and this syllabus. We highly encourage you to explore, try some of the resources that are available, and become familiar with the site early on in the course.

Canvas

The canvas site contains the gradebook, surveys, and the check-in quizzes. You are free to use the website if you want, but if there is anything that is needed on canvas, it will be directly linked on the course website.

Ed Discussion Board

The Ed Discussion board provides a place for students to get support from course staff. Ed is also the primary mechanism for announcements, though we will try to repeat announcements at the beginning of recitation and lecture for convenience.

OHQ

The course has an OHQ that we will be using for virtual office hours. Please write at least a somewhat detailed explanation of your question/problem and what you have tried so far to fix it.

Textbook

There are no strictly required texts for this course, however, some find it helpful to read the course material from a textbook. Note that none of the textbooks listed will have everything used in this course (for example, we use the LC4 programming language which only exists at UPenn). As a result, we are suggesting the following texts:

If you are looking for a more traditional textbook, past versions of the course have required or recommended:

Past versions of the course also suggested that you had a copy of a C manual or reference. We provided some online referenes with cppreference.com and linux.die.net, but here are some that have been recommended in the past:

Course Components

Lectures

There are approximately 28 lectures throughout the semester, which occur from 5:15 to 6:45 on Mondays and Wednesdays. Attendance is not mandatory, but highly encouraged and is related to the Course-wide Participation portion of the grade

Recitations

The TA’s will hold weekly recitations throughout the semester. These are not required, but participating can contribute to the course-wide participation portion of your grade. While these are not required, feedback from last fall suggests that students who attend can find these “incredibly helpful” or “life-saving”, though your experience may vary. In these recitations, TAs will often go over course material covered in the last week and/or help students with getting started on the upcoming homework. Recitations will also be a great opportunity for you to ask questions about course topics and homework assignments. Recordings will be made available for those who cannot attend.

Course-wide Participation

Course-wide participation is an umbrella term that encompasses a few things. There are three ways you can earn credit toward your course-wide participation grade:

Note that you do not have to complete all of the listed activities to get full credit for course-wide participation. Full participation points can be earned just by doing the lecture polls and weekly check in assignments. Participation grades are kept internal to the staff (i.e. not disclosed to students).

Homework Assignments

Homework will be distributed, through the course website, but will be graded, and submitted through the course gradescope. There will be approximately 12 homework assignments spread out through the semester, typically with an assignment due every week.

Late submissions and the opportunity to fix assignments will be possible. More information can be found in the assignment policies section here

Exams

There will be a midterm exam in class on October 26th. There will be a final exam as well, but details on when this is scheduled has yet to be released to me.

Policies

Getting Help

It is very important to us that you succeed in CIS 2400. As a result, we are providing many resources to help you succeed. These include:

Please do not be afraid to ask for help if you don’t understand something. We are here to help you succeed. Additionally, some of the course staff will get lonely and bored if no one shows up to their office hours.

It is also very important to us that you maintain your mental wellness throughout the course. A few points are not worth losing sleep over. Everyone on the course staff is available to chat, and you can always attend office hours for a non-academic conversation if necessary.

Additionally, if you are experiencing some unforeseen and extenuating circumstances, please feel free to reach out to course staff for help. Notably, we are still in a global pandemic! Hopefully the pandemic is winding down for everyone, but we know things can come up in the middle of the quarter (whether it is related to the pandemic or not), and we are here to help.

Inclusion

You have a right to a learning environment that feels safe, where you are treated with respect and feel that you can contribute ideas constructively. Put another way, you have the right to an inclusive learning environment.

We want every student to feel that they have a safe and healthy learning environment, and if at any point you feel like this is not the case in any way, please let course staff know and we will see what we can do to help.

You can contact staff by making a private post on Ed, reaching out to course staff via email, talking to course staff at office hours, or scheduling a 1-on-1 with the instructor here: https://www.cis.upenn.edu/~tqmcgaha/#meetings

Disability Services

The Student Disability Services (SDS) is a unit within the Weingarten Learning Resources Center (WLRC) dedicated to ensure equal access to all University programs, activities and services. They offer a wide range of services for students with disabilities that are individually designed and remove the need to reveal sensitive medical information to the course staff. Please submit a request if you will have a medical need for extensions of exam times or assignment deadlines.

Grading Breakdown

Assessment Policies

Late Policy

For exams, lecture polls and weekly check-ins, no late submissions will be accepted, or extensions granted, except outside of special circumstances.

For Homework assignments, there are no late penalties or late submissions. Instead, homeworks will have an assigned due date and the ability to request for an extension. Extensions requests must be made by making a private (but NOT anonymous) post to the Ed discussion board, where you must detail:

Your post will be reviewed by a course staff member and we will let you know if we grant the request. Note that we are lenient and will likely grant most requests, and it doesn’t hurt to ask.

It is also worth noting a few things about the system:

Midterm Clobber Policy

The clobber policy allows you to demonstrate mastery of past material with regard to exams. In particular, you can replace your midterm exam score with the score of the midterm section of the final exam. This does not apply in reverse, we will not replace your midterm section of the final with your midterm exam score.

To accommodate for the midterm subsection of the final exam being harder/easier than the midterm exam itself, we have a formula that accounts for average and standard deviation.

  1. First, we calculate Potential Midterm Clobber Score with: (final_midterm_subscore - final_midterm_mean) / final_midterm_std_deviation * midterm_std_deviation + midterm_mean, capped at 100
  2. Then we take the maximum score between the calculated potential clobber score and the grade you had on the midterm. The higher of the two will be used to calculate your final grade.

Rescheduling Exams

If you know in advance that you will be unable to take an exam, please discuss it with the instructor as soon as possible, at least a day before the exam so that the reason can be verified and plans can be put in place. Make-up exams would likely take place after the initial exam.

For emergency absences, please reach out to the instructor when possible so that plans can be put in place.

Policies regarding absences for the Final Exam are covered by the University Provost; for Spring semester courses, a makeup Final Exam would be scheduled at the start of the following Fall semester. Requests for a makeup Final Exam due to reasons that could reasonably be anticipated (e.g. traveling for summer break) are unlikely to be approved.

Collaboration & Academic Misconduct

In general, we encourage collaboration, but there is a very fine line between collaboration and cheating. We can learn a lot from working with each other and it can make the course more fun, but we also want to ensure that every student can get the maximum benefit from the material this course has to offer. Keep in mind that the overall goal is for YOU to learn the material so you will be prepared for the exams and for job interviews etc. in the future. Cheating turns the assignments into an exercise that is a waste of both your time and ours; save us both by not doing it.

Cheating consists of sharing code or solutions to assignments by either copying, retyping, looking at, or supplying a copy of a file. Examples include:

Cheating is a very serious offense. If you are caught cheating, you can expect an initiation of a cheating case in the University system and a zero for the assignment. Depending on circumstances, you may receive a failing grade in the course. Cheating is an insult to the instructor and course staff, to the department and major program, and most importantly, to you and your fellow students. If you feel that you are having a problem with the material, or don’t have time to finish an assignment, or have any number of other reasons to cheat, then PLEASE talk with the instructor, we are more than happy to work with students as needed. Just don’t cheat.

If you are in doubt about what might constitute cheating, send the instructor an email describing the situation and we will be happy to clarify it for you.
