- Final marks
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Tue, 18 Dec 2007 13:31:42 -0700 (MST)
Final marks are posted.
The final exam marks were curved by .85. The curved mark formula is:
curved = original/0.85
Thus students that have a published mark of 100 may have received a
non-curved mark from 85 to 100.
Here is some basic information about the finals mark:
Original Curved
Highest 93 100
Lowest 26 31
Mean 60.2 70.8
#students with 100 0 5
The final marks for the course are also posted. The mean for the course is
2.82, which is very close to the mean for 2nd year courses at UofA (2.83).
The histogram for marks distribution is as follows:
Mark # of students
A+ 2
A 3
A- 5
B+ 5
B 5
B- 6
C+ 5
C 2
C- 1
D+ 2
D 1
F 1
I enjoyed working with you during this Fall term. I wish all of you a very
good break and success in the remainder of your program.

- Assignments
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Tue, 11 Dec 2007 09:48:00 -0700 (MST)
Someone pointed out that one of the links in the assignments page was
broken.
I also noticed that the last assignment (about caches) was listed under
the solutions sections.
I have moved the assignment #7 up and have fixed the broken link.
In preparation for the final, it is important that you work through the
posted assignments.

- Solutions for assignments
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Mon, 19 Nov 2007 22:06:59 -0700 (MST)
I have posted some solutions to assignments in the CMPUT 229 webpage.
Because these solutions are meant for rectricted circulation, the
Assignments portion of the page is now password protected.
Use the same username/password that you already use for the Lecture Slides
portion of the website.

- Change of deadlines for Lab #4 and Lab #5
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Tue, 6 Nov 2007 15:02:08 -0700 (MST)
I just learned that several of the CMPUT 229 students are having
conflicting deadlines with CMPUT 291.
Thus I talked with the CMPUT 291 instructor and we are coordinating
the deadlines.
As a consequence the deadline for both LAb #4 and Lab #5 of CMPUT 229 have
changed.
The new deadlines are:
Lab #4: Wednesday, Nov. 14 by 6 PM
Lab #5: Wednesday, Nov. 28 by 6 PM
I hope that these extra days will reduce your stress level about
completing the assignments for both classes.
If you complete the assignments by the original deadlines, even better,
just submit it and enjoy your long weekend.

- feedback on lab grading
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Sun, 21 Oct 2007 13:30:59 -0600 (MDT)
Some students have asked about feedback on the grading of their lab
submissions.
Rather than asking the TAs to write detailed comments on each lab
submission, we will suggest that interested students see the grading TA
for one-on-one feedback. The grading TAs for labs #1 and #2 are as
follows:
Lab1: Cheng Lei
Lab2: Erkan Unal and Jichuan Shi
At the next TA meeting we will decide graders for the other labs.

- Small correction to lab #3
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Fri, 19 Oct 2007 15:51:19 -0600 (MDT)
I reposted the lab #3 specification with a small correction in the
explanation of how the coeficients are organized in the stack.
The correction is in the last paragraph before "Hints on debugging this
lab".
Submissions are now open for Lab #3.
Unal posted a solution to the INCLUDE problem in the newsgroup.
If you still have problems, please contact your TA.

- LAB #2: size of coeficients and results
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Tue, 9 Oct 2007 10:09:08 -0600 (MDT)
During our TA meeting last week we talked about the lab #3 specification
not been very clear about the size of the coeficients and results for the
polynomials in both subroutines.
To make things simpler, we decided that all coeficients will be 16-bit
integers and all results will be 32-bit integers.
I just updated the lab specification in the webpage to clarify this.
Please make sure to re-fresh your browser to get the most current
specification.

- Lab #2
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Thu, 4 Oct 2007 05:36:25 -0600 (MDT)
As some of you pointed out, the lab specification for Lab #2 did not state
what method you should use to name the files that your transmitter or
receiver is processing. There are several ways that this file name could
be obtained. Two of the most obvious ones would be:
1. Have the user type the filename (as in lab #1)
2. "hardcode" the filename in assembly --- this would involve defining an
address, and a space, in the constant area that will contain the filename.
Because we did not specify you can choose whichever method you prefer.
However, to assist your TAs with the grading of the lab, it would be very
helpful that your:
(1) state in the beggining of the comments section how the filename should
be specified (including the memory address where it is if you choose
to "hardcode" it).
(2) have a comment, or very descriptive constant or labels name at the
place where the filename should be in your code.
For grading your code will be tested with files that have not been
published.

- File I/O example
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Mon, 1 Oct 2007 15:42:15 -0600 (MDT)
There was a question about File I/O example in class today.
Please examine this example that is listed in the class website:
http://ugweb.cs.ualberta.ca/~c229/F07/resources/examples/fileio.X68
If you still have a question about it, make sure to ask your TA this week
in the lab or ask me.

- Lab2: Where to pad?
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Wed, 26 Sep 2007 20:58:18 -0600 (MDT)
A Hamming code for a four-bit nibble has 7 bits. When you want to pad this
seven bit code word with a zero to form a byte you have two choices:
(i) you can pad with a leading zero to form the byte
Bit #: 7 6 5 4 3 2 1 0
0 I4 I3 I2 C1 I1 C2 C1
(ii) you can pad with a trailing zero to form the byte
Bit #: 7 6 5 4 3 2 1 0
I4 I3 I2 C1 I1 C2 C1 0
In class and in the slides I provided an example in which the byte is
padded with a trailing zero.
The lab #2 specification asks that you pad the byte with a leading zero.
It is important that everyone does the leading zero padding in the lab
assignment that your transmitter/receiver will work well with our
receiver/trasmitter.

- Problems with website
From: amaral@cs.ualberta.ca (Jose Nelson Amaral) Date: Mon, 24 Sep 2007 16:38:31 -0600 (MDT)
Dear students:
I have fixed all known problems with the C229 webpage.
(also I figured out the black hole where my messages where going into when
sent to the moderated C229 mailing list).
Thus if you notice any remaining problem with the webpage, do let me know.
