Is there a way to recognize when a key is pressed in 32-bit masm? I know you can use interrupts in 16 bit, but how can this be done using 32-bit, since 32-bit is protected by the OS. Thanks, Tyler S. Breton

Hi all, I am after a instruction set with limited or no floating-point instructions. Why I want this is to get a compiler of this certain architecture and compile code (one with floating-point and the other without). With the resulting assembly I wanted to compare the two and do some …

Hi guys! I need the code for 32 bit division in assembly (8086 architecture) ASAP! Kindly reply to this post! Thanx!!

Does anyone knows how can I count how many digits are there in a binary number? Any ideas???

can somebody help me to know a vert efficient algorithm in dividing more than 32 bytes of number? e.g. 65534.99/2326.84=28.1648029 =>6553499/232684 =281648029 =>63 FF 9B/03 8C EC=10 C9 9B 9D how could that be? my algo is that use shifts and subs but in a bitwise manner i want to …

hi, first post here. It seems a very nice community. So, I know a little about 16bit DOS Assembly and also a little about 32bit Linux Assembly. I started learning Assembly out of curiosity, to understand C better and to learn exactly how the stack worked. I am currently learning …

-If u have a slower I/O unit, then can the CPU execute instructions while waiting on slower I/O? -In this case, this type of optimization works differently for different I/O units... -So why are there no smarter .exe files that orders the instructions for your I/O-usage? -Whouldn't that be a …

Hi this is Humza Is there anyone who has a Knowledge of MASM(MICROSOFT ASSEMBLER) OR is there any PROGRAMMER OF MASM in this community I m hurry for this.:?: :!: :rolleyes:

Hello, I am a newbie to assembly. I am working with a custom Bios that does not boot the mbr of the first drive but a custom binary file on the first partition of the first drive.
