Today I will show you how to use the MMX instructions. SSE stands for Streaming SIMD Extensions and uses 128-bit registers: XMM0 XMM1 XMM2 XMM3 XMM4 XMM5 XMM6 XMM7 The capabilities of the XMM registers are: 2 64-bit floating points (double precision) 2 64-bit integers 4 32-bit floating points (single-precision)… Continue Reading Programming with FASM – divide / multiply in Linux – part 009 .

I haven’t worked with FASM, Linux, and system functions for a while. Here is an extremely simple example for beginners with output on my nickname: mythcat.
format ELF executable 3
segment readable executable
BYTES = 255 ;number of byte 255
;read a char from input
mov ebx,0 ;0 stdin, 1 stdout, 2 stderr
;write byte read to output
;exit from program
mov eax,1 ; System call 'exit'
xor ebx,ebx ; 'xor ebx,ebx'
segment readable writeable
char_Buffer db BYTES dup(0)
CharRead db 1
The result is … as follows:
[mythcat@desk fasm]$ ./fasm char_write.asm
flat assembler version 1.73.24 (16384 kilobytes memory)
3 passes, 428 bytes.
[mythcat@desk fasm]$ ./char_write
