image/svg+xmlXORPS—Bitwise Logical XOR of Packed Single Precision Floating-Point ValuesInstruction Operand EncodingDescriptionPerforms a bitwise logical XOR of the four, eight or sixteen packed single-precision floating-point values from the first source operand and the second source operand, and stores the result in the destination operandEVEX.512 encoded version: The first source operand is a ZMM register. The second source operand can be a ZMM register or a vector memory location. The destination operand is a ZMM register conditionally updated with writemask k1.VEX.256 and EVEX.256 encoded versions: The first source operand is a YMM register. The second source operand is a YMM register or a 256-bit memory location. The destination operand is a YMM register (conditionally updated with writemask k1 in case of EVEX). The upper bits (MAXVL-1:256) of the corresponding ZMM register destination are zeroed.VEX.128 and EVEX.128 encoded versions: The first source operand is an XMM register. The second source operand is an XMM register or 128-bit memory location. The destination operand is an XMM register (conditionally updated with writemask k1 in case of EVEX). The upper bits (MAXVL-1:128) of the corresponding ZMM register destination are zeroed.128-bit Legacy SSE version: The second source can be an XMM register or an 128-bit memory location. The desti-nation is not distinct from the first source XMM register and the upper bits (MAXVL-1:128) of the corresponding register destination are unmodified.Opcode/InstructionOp / En64/32 bit Mode SupportCPUID Feature FlagDescriptionNP 0F 57 /rXORPS xmm1, xmm2/m128AV/VSSEReturn the bitwise logical XOR of packed single-precision floating-point values in xmm1 and xmm2/mem.VEX.128.0F.WIG 57 /rVXORPS xmm1,xmm2, xmm3/m128BV/VAVXReturn the bitwise logical XOR of packed single-precision floating-point values in xmm2 and xmm3/mem.VEX.256.0F.WIG 57 /rVXORPS ymm1, ymm2, ymm3/m256BV/VAVXReturn the bitwise logical XOR of packed single-precision floating-point values in ymm2 and ymm3/mem.EVEX.128.0F.W0 57 /rVXORPS xmm1 {k1}{z}, xmm2, xmm3/m128/m32bcstCV/VAVX512VLAVX512DQReturn the bitwise logical XOR of packed single-precision floating-point values in xmm2 and xmm3/m128/m32bcst subject to writemask k1.EVEX.256.0F.W0 57 /rVXORPS ymm1 {k1}{z}, ymm2, ymm3/m256/m32bcstCV/VAVX512VLAVX512DQReturn the bitwise logical XOR of packed single-precision floating-point values in ymm2 and ymm3/m256/m32bcst subject to writemask k1.EVEX.512.0F.W0 57 /rVXORPS zmm1 {k1}{z}, zmm2, zmm3/m512/m32bcstCV/VAVX512DQReturn the bitwise logical XOR of packed single-precision floating-point values in zmm2 and zmm3/m512/m32bcst subject to writemask k1.Op/EnTuple TypeOperand 1Operand 2Operand 3Operand 4ANAModRM:reg (r, w)ModRM:r/m (r)NANABNAModRM:reg (w)VEX.vvvv (r)ModRM:r/m (r)NACFullModRM:reg (w)EVEX.vvvv (r)ModRM:r/m (r)NA
