Course Plan

• Program structure and assembly programming– Data types: integers, floating points, complex data types– Arithmetic and logical operations– Control flow

• Running programs– Processor architecture– Memory hierarchy– Linking– Operating systems– Performance optimizations

SSE2030: Introduction to Computer Systems, Spring 2018, Jinkyu Jeong (jinkyu@skku.edu) 13

Course Components

• Lectures– Backgrounds– Concepts

• Projects– The heart of this course!– Provide in-depth understanding of an aspect of systems– C/Assembly programing on Linux platform– Design, implementation, measurement, optimization– Each project must be done individually

SSE2030: Introduction to Computer Systems, Spring 2018, Jinkyu Jeong (jinkyu@skku.edu) 14

Prerequisites

• Courses– Basis and Practice in Programming or equivalents– Logic circuits: ICE2001– Data structures and algorithms or equivalents:

SSE2029 or ICE2002

• Required skills– C programming – Basic knowledge of Unix/Linux systems

Grading Policy

• Grading system– Class attendance: 10%– Exams: 50%• Midterm: 20%• Final: 30%– Projects: 40%– Subject to change

• Class attendance policy– If you miss any of the exams, you will fail this course– No lateness is allowed– Up to four absences will be tolerated

SSE2030: Introduction to Computer Systems, Spring 2018, Jinkyu Jeong (jinkyu@skku.edu) 20

Class Attendance Policy

• Each of you will have a designated seat (aka �����).– Take a seat you like this Wednesday (3/7) and that seat

will be yours for the first half of the semester.– We will do the same thing after the midterm.– Instructor reserves the right to reassign seats as

necessary.

• TA will check the attendance by marking empty seats– Don’t be late; he may check the attendance at the

beginning of the class (or at any random time)

SSE2030: Introduction to Computer Systems, Spring 2018, Jinkyu Jeong (jinkyu@skku.edu) 21

Cheating Policy

• What is cheating?– Copying another student’s solution (or one from the

Internet) and submitting it as your own– Allowing another student to copy your solution

• What is NOT cheating?– Helping others use systems or tools– Helping others with high-level design issues– Helping others debug their code

• Penalty for cheating– Severe penalty on the grade (F) and report to dept. chair– Ask helps to your TA if you experience any difficulty!

SSE2030: Introduction to Computer Systems, Spring 2018, Jinkyu Jeong (jinkyu@skku.edu) 22

Summary• This course was sometimes known to be tough, but it

won’t in this semester J

• You will gain systems-level perspective, which is required whether or not you are on the system software track

• SSE2030 serves as a foundation for upcoming courses:– System Software Experiment 2 (SSE2033)– Computer architecture, Operating systems– Programming languages/compilers– Microprocessor systems, Embedded systems, …
