register operand and put the signed
result in AX.
Multiply the contents of AX by the
contents of a 16-bit memory or
register operand and put the signed
result in DX:AX.
Multiply the contents of EAX by the
contents of a 32-bit memory or
register operand and put the signed
result in EDX:EAX.

contents of a 64-bit memory or
register operand and put the signed
result in RDX:RAX.
Multiply the contents of a 16-bit
destination register by the contents
of a 16-bit register or memory
operand and put the signed result the
16-bit destination register.
Multiply the contents of a 32-bit
destination register by the contents
of a 32-bit register or memory
operand and put the signed result the
32-bit destination register.

register or memory operand by a sign-
extended immediate byte and put the
signed result in the 32-bit
destination register.
