View Full Version : Speedy (and useless) program

October 22nd, 2007, 10:50 PM
Well I got bored and decided to make a simple ASM program, it does 1000000000 decimal places of long division, not recording the results, or outputting them, or doing anything with them unless required to continue with the sum...

I just thought it's be fun to see how fast it'll work for different people, I used NASM to assemble it, and 'ld' to link it, if you're interested post the results of "time ./Program" here, the file assembles to 396 bytes for me.

section .text
global _start

mov ax, 13
mov bx, 97
mov ecx, 1000000000
mov dx, 0
mov sp, 10

div bx
mov ax, dx
mul sp
dec ecx
cmp ecx, 0
jne theloop

mov eax, 1
mov ebx, 0
int 0x80

ANy improvements to the code would be appreciated, since it's only to test very basic ASM.

My results:

real 0m32.856s
user 0m31.726s
sys 0m0.196s

i was bored, too. so i just tested it and as a newbie learned to use time, nasm and ld :KS

real 0m15.351s
user 0m14.845s
sys 0m0.104s

core2duo2ghz of course running the gibbon :)
