What is the data transfer instruction? Give example.
Data transfer instructions move data between registers or between memory and registers. For example:
• String Forms:
movsb ;move string byte by byte
movsw ;move string word by word
EXAMPLE:
Movsb es, ds ;Copies 8 bits at DS:SI to ES:DI
• New String Form (386+):
movzx ;move string with zero extended
movsx ;move string with sign extended
EXAMPLE:
movsx cx, al ;cl get al
movzx cx,al ;cl gets al
