Below is instructions in x86 assembly code using NASM syntax to copy 25 words of data from the source (SRC) to the destination (DST), assuming a 32-bit x86 architecture:
section .data
SRC dd 0x1000 ; Example source address (change as needed)
DST dd 0x2000 ; Example destination address (change as needed)
SIZE equ 25 ; Number of words to copy
section .text
global _start
_start:
mov esi, SRC ; Source address
mov edi, DST ; Destination address
mov ecx, SIZE ; Counter for the loop
copy_loop:
mov eax, [esi] ; Load a word from the source
mov [edi], eax ; Store the word to the destination
add esi, 4 ; Move to the next word in the source (assuming 4 bytes per word)
add edi, 4 ; Move to the next word in the destination
loop copy_loop ; Repeat the loop until ecx becomes zero
; Exit the program or add more code here as needed
section .bss
; Add any uninitialized data here if necessary
Adjust the code as needed.
