VPCMPW/VPCMPUW—Compare Packed Word Values Into MaskInstruction Operand EncodingDescriptionPerforms a SIMD compare of the packed integer word in the second source operand and the first source operand and returns the results of the comparison to the mask destination operand. The comparison predicate operand (immediate byte) specifies the type of comparison performed on each pair of packed values in the two source oper-ands. The result of each comparison is a single mask bit result of 1 (comparison true) or 0 (comparison false).VPCMPW performs a comparison between pairs of signed word values.VPCMPUW performs a comparison between pairs of unsigned word values.The first source operand (second operand) is a ZMM/YMM/XMM register. The second source operand can be a ZMM/YMM/XMM register or a 512/256/128-bit memory location. The destination operand (first operand) is a mask register k1. Up to 32/16/8 comparisons are performed with results written to the destination operand under the writemask k2.The comparison predicate operand is an 8-bit immediate: bits 2:0 define the type of comparison to be performed. Bits 3 through 7 of the immediate are reserved. Compiler can implement the pseudo-op mnemonic listed in Table 5-8.Opcode/InstructionOp/En64/32 bit Mode SupportCPUID Feature FlagDescriptionEVEX.128.66.0F3A.W1 3F /r ibVPCMPW k1 {k2}, xmm2, xmm3/m128, imm8AV/VAVX512VLAVX512BWCompare packed signed word integers in xmm3/m128 and xmm2 using bits 2:0 of imm8 as a comparison predicate with writemask k2 and leave the result in mask register k1.EVEX.256.66.0F3A.W1 3F /r ibVPCMPW k1 {k2}, ymm2, ymm3/m256, imm8AV/VAVX512VLAVX512BWCompare packed signed word integers in ymm3/m256 and ymm2 using bits 2:0 of imm8 as a comparison predicate with writemask k2 and leave the result in mask register k1.EVEX.512.66.0F3A.W1 3F /r ibVPCMPW k1 {k2}, zmm2, zmm3/m512, imm8AV/VAVX512BWCompare packed signed word integers in zmm3/m512 and zmm2 using bits 2:0 of imm8 as a comparison predicate with writemask k2 and leave the result in mask register k1.EVEX.128.66.0F3A.W1 3E /r ibVPCMPUW k1 {k2}, xmm2, xmm3/m128, imm8AV/VAVX512VLAVX512BWCompare packed unsigned word integers in xmm3/m128 and xmm2 using bits 2:0 of imm8 as a comparison predicate with writemask k2 and leave the result in mask register k1.EVEX.256.66.0F3A.W1 3E /r ibVPCMPUW k1 {k2}, ymm2, ymm3/m256, imm8AV/VAVX512VLAVX512BWCompare packed unsigned word integers in ymm3/m256 and ymm2 using bits 2:0 of imm8 as a comparison predicate with writemask k2 and leave the result in mask register k1.VPCMPUW k1 {k2}, zmm2, zmm3/m512, imm8AV/VAVX512BWCompare packed unsigned word integers in zmm3/m512 and zmm2 using bits 2:0 of imm8 as a comparison predicate with writemask k2 and leave the result in mask register k1.Op/EnTuple TypeOperand 1Operand 2Operand 3Operand 4AFull MemModRM:reg (w)vvvv (r)ModRM:r/m (r)NA
