MOVHPS—Move High Packed Single-Precision Floating-Point ValuesInstruction Operand EncodingDescriptionThis instruction cannot be used for register to register or memory to memory moves.128-bit Legacy SSE load:Moves two packed single-precision floating-point values from the source 64-bit memory operand and stores them in the high 64-bits of the destination XMM register. The lower 64bits of the XMM register are preserved. Bits (MAXVL-1:128) of the corresponding destination register are preserved.VEX.128 & EVEX encoded load:Loads two single-precision floating-point values from the source 64-bit memory operand (the third operand) and stores it in the upper 64-bits of the destination XMM register (first operand). The low 64-bits from the first source operand (the second operand) are copied to the lower 64-bits of the destination. Bits (MAXVL-1:128) of the corre-sponding destination register are zeroed.128-bit store:Stores two packed single-precision floating-point values from the high 64-bits of the XMM register source (second operand) to the 64-bit memory location (first operand).Note: VMOVHPS (store) (VEX.128.0F 17 /r) is legal and has the same behavior as the existing 0F 17 store. For VMOVHPS (store) VEX.vvvv and EVEX.vvvv are reserved and must be 1111b otherwise instruction will #UD.If VMOVHPS is encoded with VEX.L or EVEX.L’L= 1, an attempt to execute the instruction encoded with VEX.L or EVEX.L’L= 1 will cause an #UD exception.Opcode/InstructionOp / En64/32 bit Mode SupportCPUID Feature FlagDescriptionNP 0F 16 /rMOVHPS xmm1, m64AV/VSSEMove two packed single-precision floating-point values from m64 to high quadword of xmm1.VEX.128.0F.WIG 16 /rVMOVHPS xmm2, xmm1, m64BV/VAVXMerge two packed single-precision floating-point values from m64 and the low quadword of xmm1.EVEX.128.0F.W0 16 /rVMOVHPS xmm2, xmm1, m64DV/VAVX512FMerge two packed single-precision floating-point values from m64 and the low quadword of xmm1.NP 0F 17 /rMOVHPS m64, xmm1CV/VSSEMove two packed single-precision floating-point values from high quadword of xmm1 to m64.VEX.128.0F.WIG 17 /rVMOVHPS m64, xmm1CV/VAVXMove two packed single-precision floating-point values from high quadword of xmm1 to m64.EVEX.128.0F.W0 17 /rVMOVHPS m64, xmm1EV/VAVX512FMove two packed single-precision floating-point values from high quadword of xmm1 to m64.Op/EnTuple TypeOperand 1Operand 2Operand 3Operand 4ANAModRM:reg (r, w)ModRM:r/m (r)NANABNAModRM:reg (w)VEX.vvvv (r)ModRM:r/m (r)NACNAModRM:r/m (w)ModRM:reg (r)NANADTuple2ModRM:reg (w)EVEX.vvvv (r)ModRM:r/m (r)NAETuple2ModRM:r/m (w)ModRM:reg (r)NANA
