Systems, Apparatuses, and Methods for Reducing the Number of Short Integer Multiplications

摘要

Systems, methods, and apparatuses for calculating a square of a data value of a first source operand, a square of a data value of a second source operand, and a multiplication of the data of the first and second operands only using one multiplication are described.

1. An apparatus comprising:
decode logic to decode square-multiply (SQRMUL) instruction, the SQRMUL instruction including a first source operand, a second source operand, and a destination operand; execution logic to
calculate a square of a data value of a first source operand,calculate a square of a data value of a second source operand,calculate a multiplication of the data of the first and second operands, wherein the calculations only use one multiplication operation; and
store the results in the destination operand.
