VPMADD52HUQ

Multiplies two 52-bit unsigned integers from the source operands, adding the resulting 104-bit product to the destination operand. The instruction performs a multiply-accumulate operation specifically tailored for 52-bit precision unsigned integers.

The following table describes the supported source and destination operands.

DO NOT support LOCK

This instruction is available only in 64-bit mode. It requires AVX-512 support and specifically the AVX-512DQ instruction set extension.

The operation is performed on unsigned 52-bit integers; any bits provided in the source registers beyond the 52nd bit SHALL be ignored. Failure to clear higher-order bits in the input registers may lead to logically incorrect results if the software expects 64-bit multiplication. The destination register MUST be properly initialized to zero if the intended operation is a simple multiplication rather than an accumulation.
