Text:

1. Computer Systems: Architecture, Organization, and Programming, Arthur B. Maccabe, Irwin, 1993.

2. CSE 360 Course Packet -- You will need the Packet to do course assignments.

CIS360 6

Grading Policy: An assigned grader will grade all homeworks

and labs – your lecturer will grade the midterm and final.

Missed assignments or tests without prior approval will receive a grade of zero.

Reasonable excuses must be given in writing to me one week prior to the due date or test date, at which time the circumstances will be evaluated, and approval granted or rejected.

No late homeworks or labs will be accepted. Exams are closed book, closed notes, and cover

all of the material up to that point.

CIS360 7

Grading Weights:

Homeworks (6) 25% as assigned

Labs (3) 25% as assigned

Midterm 20% around the 7th week

Final 30%as indicated in master schedule

Grading Scale - to be determined

Students with Disabilities

If you need an accommodation based on the impact of a disability, please contact me to arrange an appointment as soon as possible.

Office for Disability Services – verifies the need for accommodations– Helps develop accommodation strategies.

If you have not previously contacted the Office for Disability Services, I encourage you to do so.

CIS360 9

Academic Misconduct

Academic misconduct is defined as any activity which tends to compromise the academic integrity of the institution, or subvert the educational process.

University policy requires that all cases of suspected academic misconduct be submitted to the Committee for Academic Misconduct for a hearing and evaluation. – Any academic misconduct will be dealt with

via the appropriate University authorities.

CIS360 10

Academic Misconduct

Homework, lab assignments, and exams are to be your own work.

High-level discussion of assignments is encouraged, but the more specific your discussion, the closer you come to cheating. – The policy on collaboration with others is

fairly liberal -- but please don't be tempted to test its limits.

CIS360 11

Academic Misconduct

You may not write or otherwise record any part of your solution to an assignment while someone is helping you.

You may not take a physical or electronic copy of any part of a solution to an assignment from anyone.

You may not give a physical or electronic copy of any part of a solution to an assignment to anyone.

CIS360 12

Academic Misconduct You are encouraged to talk with others

(especially others in the class) about the design, logic, and implementation of a program. – do not give anyone or take from anyone

written or recorded material– write up your own solution without assistance.

Professional ethics: – You may not turn in an assignment solution

from a previous quarter's offering of the course

CIS360 13

Expectations

Read your e-mail Read, reply to the class Newsgroup Attend class Complete homeworks and labs on time Read the assigned pages from the text

CIS360 14

Can I change my section?

Not until Brutus updates – at the end of the first week– only if there are seats available.

Priority will be given– CSE Majors that are Graduating Seniors– CSE Majors– People who attend class the first week

CIS360 15

Can I work on labs from home?

Yes, perhaps you can, but on your own initiative, without special assistance from your instructor or grader.

Theoretically, the assembler used in this class is one that can be downloaded for free from the Internet.

Don’t ask me how to find or use these programs.

You will still have to use the stdsun.cse.ohio-state.edu submit program to turn in your assignments.

CIS360 16

Working from home

Programs supporting the secure shell (ssh) and file transfer (ftp) protocols can be especially useful in this regard.

Your computer account for this class is on stdsun.cse.ohio-state.edu.

Information about remote usage of the cse network may be found at – www.cse.ohio-state.edu/help/uguide/

node159.html#sec:remote_usage

CIS360 17

Who do I approach if I have a problem with grading?

For labs and homework, email your grader.

For exams, email (or see) me– Wayne Heym, w.heym@ieee.org

CIS360 18

The Class Newsgroup

Server: news.cse.ohio-state.edu   Group: cse.course.cse360 It’s a place for students to discuss

issues related to course work. Post any questions you might have. Use discretion when making a posting. Look out for important announcements. Instructors/Graders answer questions

whenever they can.

CIS360 19

Course Objectives Principles of Computer Organization and

Architecture– Basic Machine Representation of Signed

Integers, Character Strings, Arrays, Stacks, Records, Linked Lists;

Assembly Language Programming. – Fundamentals of Computer Instruction Set

Architectures; – Low Level Algorithms for Data Manipulation and

Conversion and Parameter Passing

CIS360 20

Course Objectives Understanding the architecture (how the

computer executes assembly language instructions) is the more important aspect of a course at this level.

The fundamental concept to understand is that everything in the computer is represented by ones and zeros (by electric current flowing or not flowing at a specific place, or by something being magnetized one direction or the other, etc.).

CIS360 21

Course Objectives At the lowest level, this course will

cover various binary formats of assembly language instructions and various ways in which data can be represented using ones and zeros and how these can be organized into a program.

At high levels, assembly language programming techniques will be studied and a specific assembly language will be used to illustrate these techniques.

Homework #0-0

This homework is designed to help you to get acquainted with this course, and to get started. 

Surf to my webpage and find the following: – Office Location– Office Hours– Email Address– Course Overview– Course Schedule– Date/Time of the midterm and final

examination

CIS360 23

Homework #0-1

Purchase the textbook written by Maccabe.

Find the reading assignment for the second class-meeting in the CSE 360 Course Schedule, and read the assigned material. 

Pledge to do the reading assignment before each class meeting.

CIS360 24

Homework #0-100

Look over the Course Packet – It contains a wealth of information crucial

to pursuing this course of study, including in-class exercises, and the overhead transparency slides.

Plan to bring the Course Packet to each class meeting after today.

CIS360 27

Homework #0-101 Find answers to the following questions.

– If you fail to electronically submit a homework or laboratory assignment by the due date/time Will you later be able to receive any credit for that

assignment?

– Suppose you have electronically submitted on time, but, later, you electronically submit again, but after the due date/time. Will you receive any credit for that assignment?

– Assignments are acceptable only as plain text files; be sure you know what a plain text file is.

– Where can you find Homework #1 and later assignments, as they become available?

CIS360 28

Homework #110

In the Course Packet, read the section of the Syllabus on “Academic Misconduct.”

Information Representation 1 Positional Number Systems: position of

character in string indicates a power of the base (radix). Common bases: 2, 8, 10, 16. (What base are we using to express the names of these bases?)– Base ten (decimal): digits 0, 1, 2, 3, 4, 5, 6, 7, 8,

9 form the alphabet of the decimal system. E.g., 31610 =

– Base eight (octal): digits 0, 1, 2, 3, 4, 5, 6, 7 form the alphabet.

E.g., 4748 =

CIS360 33

Information Representation 2

– Base 16 (hexadecimal): digits 0-9 and A-F. E.g., 13C16 =

– Base 2 (binary): digits (called “bits”) 0, 1 form the alphabet.

E.g., 100110 =

– In general, radix r representations use the first r chars in {0…9, A...Z} and have the form dn-1dn-2…d1d0. Summing dn-1rn-1 + dn-

2rn-2 + … + d0r0 will convert to base 10. Why to base 10?
