[Dec. 19, 2005]
Unclaimed marked assignments, midterms, and laboratory reports can now be picked up from a labelled tray in the main ECE office. The marked assignment #5 solutions will be distributed in the tray towards the end of next week (approx. Dec. 15). Model solutions to Assignment #5 will be posted on this website on Monday, Dec. 12. [Dec. 8, 2005]
In accordance with the official schedule for the final examinations, the final examination for CMPE 401 will be held in the NREF building, on the second floor, in room 001 (NRE 2 001) on Monday, December 19, 2005. The exam will start promptly at 9:00 am and will last 2 hours. You will be permitted to freely consult one hardcopy of the lecture slides. You are also permitted to use any kind of electronic calculator. In addition, you are also permitted to bring a copy of the M68000 Programming Reference Card. You will not be permitted to consult marked assignment solutions, marked midterm examinations, or model solutions for assignments or any past examinations. The questions on the examination will cover the entire contents of the courses, although there will be somewhat more emphasis on material covered in the second half of the course. [Dec. 6, 2005]
The CCNET website for this course has now been loaded up with the student records, and currently holds the grades for assignments 1, 2 and 3 as well as the midterm. You will need to complete a short registration process at the course's CCNET site in order to see your grades. At the course CCNET home page, click on the STUDENTS link to get to the student login prompt. You can then register to use your account using your student ID number. Please report any errors either to Bruce Cockburn or Nancy Minderman. [Nov. 18, 2005]
Lab #4 was released in class on Monday. Do not forget to complete the prelab before your lab section. Doing the prelab will greatly reduce the amount of time you spend on this lab. The lab4 tar file is now ready. [Nov. 15, 2005]
Model solutions for the midterm are now available in both HTML and pdf formats. The average mark on the midterm was 56.18%. [Nov. 12, 2005]
Lab #3 was released in class on Friday. The specification for the bonus section has been expanded. Consult it if you intend on completing the bonus section. Do not forget to complete the prelab before your lab section. The lab3 tar file is now ready. [Oct. 31, 2005]
The midterm exam conditions were announced in class on Friday, October 28. The exam will cover all of the material that has been discussed in the lectures, up until the end of section 8. You are permitted to bring the following aids into the class room: a hardcopy of the lecture notes; an electronic calculator; a 68000 Programmer's Reference Card; a copy of the MicroC/OS-II programming reference sheets from the course website. You are not permitted to bring in any model solutions of assignments or past examinations. You are not permitted to bring in a textbook. [Oct. 30, 2005]
If you need to allocate space for a variable that persists between calls of PollDuart add the following code to the bottom of your duart.s file. Replace the .end directive at the bottom of the file with:
```
		.data
		label:
		.byte 0
		.end
```
and replace label with an appropriate name for your variable(s). Treat 'label' as an absolute long for addressing-mode purposes. [Oct. 19, 2005]
The lab2 tar file has been released. [Oct. 3, 2005]
Lab #2 has been released. The tar file will be released on Monday. Remember to complete the pre-lab before coming to your lab section. Open House demos will be taking place in the lab tomorrow, Saturday the first of October from 10:30 to 3:00 or so. My apologies for the disruption. [Sept. 30, 2005]
The lab1 tar file was released yesterday. [Sept. 20, 2005]
Lab #1 has been released. Do not forget to complete the prelab before the lab section starts. Remember to pick up your lab kits from the EEClub. Pick up the breadboard and cables from the lab instructor in E5-002 today from 2-5PM and Monday from 2-5PM. The lab tar file will be ready on Monday for download. I will make an announcement when it is ready.[Sept. 16, 2005]
The course notes are now on sale at the EE Club office in ETLC E2-040B. The price is $9.00. Please pick up a set before the lecture on September 9. [Sept. 8, 2005]
Marks and other information will be made available via CCNet at CMPE401 CCNet. [Sept. 6, 2005]
The website for fall 2004 semester has been archived and can be accessed here. [June 1, 2005]

Code of Student Behaviour:

It is the student's responsibility to be familiar with, and to adhere to, the terms of the University of Alberta's Code of Student Behaviour. Included in the Code are descriptions of unacceptable behaviour for students attending the University, the sanctions for the commission of academic offences, and explanations of the complete discipline and appeal procedures. In particular, please note the definitions of plagiarism in section 30.3.2(1), of cheating in section 30.3.2(2), of misrepresentation of facts in section 30.3.6(4), and of participation in an offence in section 30.3.6(5). For example, cheating includes the submitting of the words, ideas, images, or data (including computer programs) of another person as the student's own in any academic writing, essay, thesis, research project or assignment in a course or program of study. Penalties for academic offences range from a written reprimand up to expulsion from the University.

Supplementary Reference Materials:

Please do not feel obligated to buy copies of any of these books. They are not required for the course, but you might find some of these titles useful to supplement the lecture and laboratory material. Limited numbers of the book on MicroC/OS-II by Jean Labrosse are available in the University bookstore. This book would be a useful reference for the laboratory exercises, and might be useful later on for project courses.
