Count to 10,000 in ASM
« on: February 18, 2012, 01:57:59 am »
Hi,
I was wondering if somebody could make me a .8xp in ASM that counts to 10,000 and displays the number it is on on the screen. This is so I can test the speed of my calc and compare it to other stuff.

Thanks, and have a nice day,
nxtboy III

Well, you could use this, but how are you planning to test speed with it?

But it's not very useful at all, since most of the time it takes is to display the number, so it's not much faster than doing it in TI-BASIC (left side is ASM, right side is BASIC):

Is there a way to make it not display a new line each time? Just on the same line?

It would just keep going to the right, and after three numbers you wouldn't be able to see any more.

Oh. Well I was doing this so I could test the speed between my NXT and my calc.

maybe add extra clrLCDFull somewhere in the loop? even though it will slow things down? or set pencol or whatever it's called?

I made a program for it on my NXT in assembly that counts and displays the number.(It displays the number in the same place the whole time.) It counts to 10,000 in about 4 seconds.

EDIT: i'm sorry. i accidentally hit the modify button instead of quote =/

Without displaying numbers, an optimized z80 assembly loop structure could count to 10000 in about 1/30th of a second. Although I would not recommend comparing processor/language speed by seeing how fast they can count to 10000, simply because there are multiple variables that will skew the results an extreme amount; display or not, scroll or not, how fast the system text routine is, how the screen is updated, and so on. If you have a project in mind, I would say the best way to compare speed is simply to start coding the project for both platforms and compare simplified, test versions of them.

??? Are you sure it can count to 10,000 in about 1/30th of a second?
That seems super fast.......
Well, here it is for my NXT:(Sorry it's an avi)

For the calc one:
Could you edit the TI 84 program so it stops when it gets to 10,000?

you could add this at the end of the loop: If Ans=10000:Stop

Do you think you could add it and compile it to an 8xp for me? I don't know how.

Well there's this if this helps:

#include    "ti83plus.inc"
#define     progStart   $9D95
.org        progStart-2
.db         $BB,$6D
   bcall(_ClrLCDFull)
   bcall(_HomeUp)
    ld  HL, 0
Loop:
    push    HL
    bcall(_DispHL)
    bcall(_NewLine)
    pop     HL
    inc HL
    ld  DE, 10000
    xor A
    sbc HL, DE
    add HL, DE
    jr  nz, Loop
    ret

oh. I thought you were asking about TI-BASIC file XD
sorry, I don't have a compiler.

What about in BASIC?
Is there another easy way I can compare speed?


EDIT: My NXT counts to 1 million in about 39 seconds in assembly.
