Here is a link to a complete (I think) list of NASM instructions, which I presume also covers the x64 bit instruction set for Intel processors. However, I was hoping there would be a complete list...

Dec 4, 2018 · 0 What does the 'and' instruction do in assembly language? I was told that it checks the bit order of the operands and sets the 1s to true and anything else to false, but I don't know what it …

Nov 2, 2009 · As others have pointed out, LEA (load effective address) is often used as a "trick" to do certain computations, but that's not its primary purpose. The x86 instruction set was designed to …

I don't want to implement instructions like those. I can imagine a couple of instructions which (I believe) must always be present in any assembly language, such as MOV to move bytes around and JP to …

I've encoutered these to instructions IN & OUT while reading "Understanding Linux Kernel" book. I've looked up reference manual. 5.1.9 I/O Instructions These instructions move data bet...

The importance of CMP applies mostly in conditional code execution (Jump - See : assembly_conditions). When the processor executes a conditional-jump jcc instruction, it checks the …

Nov 15, 2016 · How to write the equal condition (in the question) in assembly? Your example has an else statement while mine uses an else if.

Apr 5, 2014 · I created a very simple assembly program that prints the letter 'a' in DOS. I opened it in a hex editor and the result was this: Assembly code: mov ah, 2 mov dx, 'a' int 21h Hex code B4 0...

Jan 3, 2011 · When reading about assembler I often come across people writing that they push a certain register of the processor and pop it again later to restore it's previous state. How can you push a …

Mar 28, 2009 · I heard there is Intel book online which describes the CPU cycles needed for a specific assembly instruction, but I can not find it out (after trying hard). Could anyone show me how to find …
