摘要
Embodiments of systems, apparatuses, and methods for broadcast arithmetic in a processor are described. For example, execution circuitry executes a decoded instruction to broadcast a data value from a least significant packed data element position of a first packed data source operand to a plurality of arithmetic circuits and for each packed data element position of a second packed data source operand, other than a least significant packed data element position, perform the arithmetic operation defined by the instruction on a data value from that packed data element position of the second packed data source operand and all data values from packed data element positions of the second packed data source operand that are of lesser position significance to the broadcast data value from the least significant packed data element position of the first packed data source operand, and stores a result of each arithmetic operation into a packed data element position of the packed data destination operand that corresponds to a most significant packed data element position of the second packed data source operand.
