command movhpd destination, source

Copies the data from source operand to destination operand. Used for Moving High-Packed Double-Precision Floating-Point Values. The movhpd command can only be used with xmm registers.


Moves a double-precision floating-point value from the source operand (second operand) to the destination operand (first operand). The source and destination operands can be an XMM register or a 64-bit memory location. This instruction allows a double-precision floating-point value to be moved to and from the high quadword of an XMM register and memory. It cannot be used for register to register or memory to memory moves. When the destination operand is an XMM register, the low quadword of the register remains unchanged.
