Assembly Applications

[skilletsteve]

Before visiting this forum I had never heard of Assembly programming. Does anybody know of any applications written in assembly? If anyone does I would like to check them out to help me understand what assembly was used for.

[Ronin]

Good question. I don't know of any applications that are actually wrote in assembly. I'd like to see some as well.

I have a few, one calculates the quadratic equation, I'll try to find the code for you

[Sionofdarkness]

I wrote a program on my calcluator that did the quadratic equation, but I'd bet $3,000,000 that the assembly version is more complicated.

[TcM]

Well if im not wrong Delphi ( or some other language ) supports inline Assembly!

[Blaze]

interesting, how do you add assembly to delphi?

[kromagnon]

This is a program I wrote a couple years ago. It is written in MIPS assembly language

#$s0: counter
#$s1: the final value is passed to this for each problem
#$s2: used as a "counter" in the Fn problem
#$s3: used as a "counter" in the Fn problem

print_int = 1
print_str = 4
Fn_1	  = 1

Well I dont use delphi but I saw that on a site! but cant find it! but you just write

asm
Assembly code here
end;

thats all! look ata this site! http://www.alstonlabs.com/assembly.htm

C and C++ also support inline assembly. Many C/C++ libraries use assembly at to perform low-level system-specific tasks.
