here is the link to the "virtual computer" we are going to program in
http://www.course.com/downloads/computerscience/aeonline/6/4/index.html

and these are our "objectives": (try to make them if you can)

(please forgive me if there are some bad spelling or grammar, I am converting from norwegian to english, and I dont know every word in english so I use synonyms)
Quote: "
make an Assembly program for each of the expressions below:
* x = x + y*z (x,y,z must be <> 0 at start)
* repeat until x = 0 (x = 3 at start, x must be dec. by 1 each loop)
* if x < y then
x = z
else
x=y
endif (at start x=3, y=5, z=7)
the assembly code must be written, tested and documented in your answer. you must also describe how data moves fr4om memory to processor and back again.
"


can somebody help me with this?

its me n0id!

That looks like a standard Java education question.

Write the Pseudo-code for it, and go from there.

we are going to use this wierd language Ive never used before, my teacher sais it is almost the same as motorola uses.
but look what I found out: (commands)
add = add value to variable
mul = multiply value with variable
sto = save value to variable
hlt = end program
I dont understand anything. must ask someone, so I got here.
but I can ask my teacher, then he'll get mad. (he's crazy)

its me n0id!

Tell your teacher you're REALLY INTERESED in how these funny chips work. Say you are not sure why it works and get him to demonstrate it. If he won't do that then you best start going to your lessons or pay attention in them. IF he goes mad at you then he's a complete tit. Ask your mates at school if they understand it. If they don't then you best get the teacher to explain.
I went to college and the lecturers could go over and over this stuff until we all had it. Only reason they did that is because the whole class was lazy and didn't care. Show you care about these AMAZING chips because they do control EVERYTHING these days... even your toasters.

Heh, I'd like to help you, but the only ASM I've got any experience with is for the 6502 (used in nintendos) processor. That and the Neander, which I doubt will be of use to anyone.

x = x + y*z (x,y,z must be <> 0 at start)

in x86 assembly that would be



assuming x,y and z have been declared as 16-bit variables.

That last one's quite fun to do - took me about 5 minutes but I got there in the end.
My answer (if you want it):



If you get any more difficult problems, could you post them? I'd like to give them a try. ASM always sounded like more hassle than it was worth but I'm now tempted to give it a go if it's anything like that.

dude.... you did it

you did the most difficult one!

we have these tasks, we can choose either yellow, blue or red.
red is the hardest, yellow is easiest. (I chose red)

my teacher said that last one (the one you just did) was the hardest part. and no student had made it ever. (dont know if thats true).

but you did! dude, you are good. have you trained or did you just think of something and it worked? (like was you born with skills?)
---------------------
edit:

sorry, I dont have any more. but I can ask my teacher if he has any.

its me n0id!

Hehe, no worries.
Assembly is a different way of thinking from normal high-level coding, I sometimes find it more enjoyable aswell :-P
