Special Instructions

CBW

• convert byte to word
• sign extends 8 bits in AL to 16 bits in AX

CWD

• convert word to double word
• sign extends 16 bits in AX to 32 bits in DX:AX

CWDE

• sign extends 16 bits in AX to 32 bits in EAX

CDQ

• sign extends 32 bits in EAX to 64 bits in EDX:EAX

MOVESX register, memory/register

• generalized form of CBW/CWD/CWDE

BSWAP register

• converts between 32-bit little endian and big endian values
