| HW4 graded | 4th exercise is returned - you can see your grades in GR++, and from Monday morning take the printed handout from Taub ground floor. In the printed part there is also explanation of why you lost points in the wet part, so take a look at it before asking.
Regarding the exercise - first of all a few good things some of you did in this exercise:
* Calculating the guard course in advance, so that when there is a need to make a guard step all there is to do is go to the next cell in the array.
* Creating the map in advance, so that when it should be printed all there is to do is to put the guard in the right place, and remove him when the printing is finished.
* Using traps to do the guard step in lower priority than that of clock interrupts.
And now for the things that were not so good (Maximum number of points reduction for each mistake in parentheses). Take a deep breath...
In the wet part:
A. Some of you didn't take into consideration the fact that the guard might move while the map is being printed. This can cause the map to have 2 guards or no guard at all. (7)
B. There were some compilation problems, mainly because of using labels not in the accurate way they were given, and not removing the data section. (4)
C. A few programs didn't react to the keyboard at all(24), or didn't handle quick multiple 'p's and got stuck. (12)
In the dry part:
A. External documentation should have contained several things:
1) General description of the program and what it does. (2)
2) List and description (could be in internal documentation) of functions/routines in your program, including priority policy. (5)
3) List of global variables and globally used registers (could be in internal documentation). (3)
4) Description of guard advancing algorithm. (3)
Saying you didn't know these thing must be in the documentation won't help, since you saw in exercise 3 how a program and function documentation should look like, and many people DID understand how it should be done.
B. Calculation of the guard's next movement shouldn't be within the clock isr (and that includes calculation in a function called from within the routine). (5)
C. Asynchronic printing does not mean using IOT interrupt, but mainly not doing busy waiting for printing. Anyone who did not use printer interrupt didn’t use asynchronic printing. (8)
D. Turning off the clock IE flag means loosing clock ticks (10)
E. Some people changed the PSW in order to change priority. This is not recommended and dangerous, and should be done very carefully - baring in mind that there could always be an unexpected interrupt with higher priority! This didn't cost you points.
I will not be in my office (and therefore not be able to answer emails regarding ATAM) until reception hours (Tuesday 12:00 to 13:00). All emails including those about 3rd hw will be therefore answered on Tuesday.
Good luck in the exams,
Sivan

| HW4 clarifications | Hello students,
Here are some clarifications about HW4:
1. As many of you noticed there are a few mistakes in the example given.
These are the correct values:
waitTick: .word 500.
startI: .word 3
startJ: .word 2
2. You are allowed to ignore new printing requests (user presses 'p') when you are in the middle of handling current request (i.e. printing the map),
You are not allowed to ignore clock ticks and other input (user presses 's' or 'q').
3. You can assume that waitTick is big enough to insure that you will finish the previous guard step before you should start a new one.
You may also assume that a guard step is short enough to be finished during one clock tick, but if you do not assume that and you will explain how, you will get a bonus.
4. You can never ignore a clock tick, and you should handle as many of the other interrupts as possible.
Any other assumption you make in your solution should be clearly stated in the external documentation.
Good luck

| Final clarification (I hope) regarding ex. 3 | Since several students had asked this question, I will publish the answer to it here –
When you are told NOT to submit the main program, it means also NOT to execute the stack initialization in your code.
The stack initialization will be done by the auto checker.
If you initialize the stack in SOLVE (for example), it means that the routine who called SOLVE won’t know where to return to (if the linkage register would have been PC) or that the value of r5 will get lost (in our case, when the linkage register is r5) + the routine that called SOLVE will return, but all the content of its stack will be lost.
Regarding "sol_found", as written in the assignment, you must define it and submit it in your code. Once again – submit all the variables you are using BESIDES "output_arr" (and the "main" function).

| More clarifications regarding ex. 3... | Dearest students,
1. All common area variables (sol_found \ K \ etc') can be defined in the data section, in the end of the program. They can be defined in a lot of other places, but this form is the most elegant (although any form that works is acceptable).
2. You should use .=torg + in the beginning of your code, to avoid overwriting important values that are stored in the smaller addresses. Use 1000 or 2000 for this.
3. If you get a message "environment too large" when you're trying to run as11, try execute "set path=" in the DOS shell and try again.
4. if you encounter weird problems like exercises that seems like stuck, but when pressed CTRL+C shows the correct solution, try using the newest simulator.

| Clarifications regarding the clarification regarding EX. 3 | Dear students,
Regarding the clarification I published several hours ago :
1. r5 is the linkage register for SOLVE. It means that you have to finish SOLVE with "rts r5". The parameter K is still being passed through r3.
2. You do not have to re-submit your dry part. Submitting the (corrected) wet part will do. While the auto-checker must see that you're using the correct linkage register in order to understand that your program works, our human checker's brain is much more complicated - he can understand that by just looking at your (un-corrected) code.
3. To all the people who are complaining that it is not fair (since they won't have enough time \ it discriminate against the people who finished early \ other reasons) –
a) 2 days should be enough in order to change "pc" into "r5". It should take you about 20 seconds to do so. The rest 172780 seconds you can use in order to re-arrange your registers and re-submit the wet part electronically.
b) If you had submitted the code without asking me why didn't I stated which register is the linkage register for SOLVE (and just improvised and selected some register), you have shown that you don’t fully understand this mechanism. Instead of telling us that it's not fair that you have to re-submit the wet part, thank us for making sure you won't forget this (important) topic in the exam… :-)

| Important notice regarding EX. 3 | Unfortunately, due to a problem in the electronic systems, many of you did not receive the following clarification:
"The linkage register to SOLVE routine must be r5".
Notice that if you use other registers as the linkage register the program will not work correctly, since our MAIN routine will call your SOLVE with r5.
Since many students have already submitted their works, using other registers instead of r5, you are given a postponement until Sunday evening.
Some 20 students had sent me questions via mail regarding this issue. The last 5 of them got their replies starting with "AS WRITTEN IN THE EXERCISE….".
Since this clarification was not published, there was no way you could have known this, so - to those who got this message - please accept my apology.
Have fun finishing the assignment,
Yaniv

| Homework #2 graded | Hello,
The 2nd exercise is graded and returned. There were a few VERY good handouts, keep on the good work.
Points were taken mostly for these reasons:
1. If there was no .s11 file: -10 points
2. If the file did not compile and run according to the specifications: -10 ponits
3. Lack of external documentation: -15 points
4. Your programs were tested with several inputs. Wrong result for each output array or vlaue for one of the inputs: -2 points
The most pupolar mistakes were bad handling of SIZE=2, and miscalculations of negative weighted average and median.
Have fun,
Sivan

| Assignment #3 corrections | 1. In routine CheckColumn, notice that in two places, when there was written `k` it is now written `the parameter from the stack`.
2. Notice that the drawing in the exercise is of a legal size-5 board, but this is NOT the solution the algorithm will give. The algorithm will return another legal size-5 board. The algorithm counts from larger numbers (=borads) to smaller numbers, thus – it will discover another solution before the given one.. |

1. The names of check_counter and check_column were changes since the assembler changed it to the same thing.
2. The function check_column now receives also the k value as a parameter in common area (in addition to the other parameter it receives in stack).
3. The function dec_counter was changed. Minor changes in number of sections (in section "d").
4. You can assume that k > 1.

| Assignment #2 clarification | A few things regarding the submission of exercise 2:
1. Do not submit the SIZE definition, the “input” label and all the output labels.
You should submit all the labels you added for your own use.
2. Internal documentation – Comments in the code itself, explaining important lines roles.
External documentation – An external document (written in WORD or some other text editor), explaining in
general about your program and main algorithms you used.
Good luck,
Orly

| Assignment #1 is graded | First HW is checked
You can find your printed handouts in the usual place (ground floor), and see your grades through the site and GR++.
Some of you made some mistakes in this exercise, so here is a list of the common mistakes to help you improve in the next exercises:
1. In the electronic submission - some of you did not send the .s11 file as requested. Usually this means 0 in the wet part, but because of this being first time, other file types were checked manually and some points were given. Read carefully what you should submit.
2. You received a code with comments, and some of you erased them. Internal documentation is ALWAYS very important, so make sure your future programs contain good comments.
3. If you wish to show the content of the array "sum" in the simulator, it is not enough to write 'e sum', because this only shows the first member of the array. The way to do it is to show a range of cells from the memory, for instance by 'e sum, sum+8'.
4. Some of you handed the log file with extra printing - the whole memory or the trace of the whole program when it ran. Print only what you are asked for, and unless it is specified do the running of the program with 'g' and not 't'.
Good luck with the next exercises,

| Assignment #2 - Corrections | 1. When you calculate weighted average
or median and you get a "SHEVER MEORAV" all we ask you
as an output is the integer part of it, not the "floor" value
as written in the exercise. Notice that for positive numbers
those values are the same, but for negative they aren't
(if you get, for example, -2.4 as the median, we only want -2 as
an answer, and not -3).
2. You can assume that all weights are positive numbers (>0).

A version of HW2 with the corrections has been published.
Notice there are 2 more changes there:
1. the SIZE definition changed to SIZE=10. (decimal 10).
2. You may assume that all the results of MUL and ADD
operations can be stored in one WORD. Notice that this
assumption is not necessary for solving the exercise
(it just makes things easier for you).
Good luck!

| HW2 clarifications | Hello All,
Few things regarding HW2:
1. There is a small mistake in the given example:
The values that should be in the output are: 2, -1, -2, 8, 3.
2. Small correction to make things easier: All values and weights are SIGNED
numbers, and not as written in the exercise (that weights are UNSIGNED).
3. You may assume, for your convenience, that the result of the
MUL operation can be stored in one WORD.
4. I will have a special reception hour this week, on Tuesday 15.4,
