Figure 4-31. Floating-Point Move Operations
The MOVHPS and MOVHPD instructions copy a vector of two single-precision floating-point values
(MOVHPS) or one double-precision floating-point value (MOVHPD) from a 64-bit memory location
to the high-order 64 bits of an XMM register, or from the high-order 64 bits of an XMM register to a
