In section 4.3 of Intel 64® and IA-32 Architectures Software Developer\'s Manual. Volume 1: Basic Architecture, it says:
I have to approximate execution time of PowerPC and x86 assembler code.I understand that I cannot compute exact it dependson many problems (current processor state - x86 processor dicides internal ins
I\'m fed up with this. I\'ve been trying to just get a grip on assembly for awhile, but I feel like I\'m coding towards my compiler rather than a language.
I have 2 simple, but maybe tricky questions. Let´s say I have assembler instruction: MOV EAX,[ebx+6*7] - what I am curious is, does this instruction really actually translates into opcode as it stand
This is probably trivial, but for some reason I can\'t it to work. Its supposed to be a simple function that changes the last byte of a dword to \'AA\' (101010开发者_StackOverflow10), but nothing happ
What amount of memory is available (theoretically) to application on 32 bit s开发者_JAVA技巧ystem? Different OSes? 2 or 1 Gb?
What does th开发者_StackOverflowis instruction do? mov (%r11,%r12,1), %edx Look here. It says In the AT&T Syntax, memory is
Why are there only four registers in the most common CPU (x86)?Wouldn\'t there be a huge increase in speed if more regis开发者_StackOverflow中文版ters were added? When will more registers be added?The
The following code int _main() {return 0;} Compiled using the command: gcc -s -nostdlib -nostartfiles 01-simple.c -o01-simple.exe
I have an inline assembler loop that cumulatively adds elements from an int32 data array with MMX instructions. In particular, it uses the fact that the MMX registers can accommodate 16 int32s to calc
