VPDPWSSDS — Multiply and Add Signed Word Integers with SaturationInstruction Operand EncodingDescriptionMultiplies the individual signed words of the first source operand by the corresponding signed words of the second source operand, producing intermediate signed, doubleword results. The adjacent doubleword results are then summed and accumulated in the destination operand. If the intermediate sum overflows a 32b signed number, the result is saturated to either 0x7FFF_FFFF for positive numbers of 0x8000_0000 for negative numbers.This instruction supports memory fault suppression.Opcode/InstructionOp/En64/32 bit Mode SupportCPUID Feature FlagDescriptionVEX.128.66.0F38.W0 53 /rVPDPWSSDS xmm1, xmm2, xmm3/m128AV/VAVX-VNNIMultiply groups of 2 pairs of signed words in xmm3/m128 with corresponding signed words of xmm2, summing those products and adding them to doubleword result in xmm1, with signed saturation.VEX.256.66.0F38.W0 53 /rVPDPWSSDS ymm1, ymm2, ymm3/m256AV/VAVX-VNNIMultiply groups of 2 pairs of signed words in ymm3/m256 with corresponding signed words of ymm2, summing those products and adding them to doubleword result in ymm1, with signed saturation.EVEX.128.66.0F38.W0 53 /rVPDPWSSDS xmm1{k1}{z}, xmm2, xmm3/m128/m32bcstBV/VAVX512_VNNIAVX512VLMultiply groups of 2 pairs of signed words in xmm3/m128/m32bcst with corresponding signed words of xmm2, summing those products and adding them to doubleword result in xmm1, with signed saturation, under writemask k1.EVEX.256.66.0F38.W0 53 /rVPDPWSSDS ymm1{k1}{z}, ymm2, ymm3/m256/m32bcstBV/VAVX512_VNNIAVX512VLMultiply groups of 2 pairs of signed words in ymm3/m256/m32bcst with corresponding signed words of ymm2, summing those products and adding them to doubleword result in ymm1, with signed saturation, under writemask k1.EVEX.512.66.0F38.W0 53 /rVPDPWSSDS zmm1{k1}{z}, zmm2, zmm3/m512/m32bcstBV/VAVX512_VNNIMultiply groups of 2 pairs of signed words in zmm3/m512/m32bcst with corresponding signed words of zmm2, summing those products and adding them to doubleword result in zmm1, with signed saturation, under writemask k1.Op/EnTupleOperand 1Operand 2Operand 3Operand 4ANAModRM:reg (r, w)VEX.vvvv (r)ModRM:r/m (r)NABFullModRM:reg (r, w)EVEX.vvvv (r)ModRM:r/m (r)NA
