Abstract: In one embodiment of the invention, a processor device including a storage location configured to store a set of source packed-data operands, each of the operands having a plurality of packed-data elements that are positive or negative according to an immediate bit value within one of the operands. The processor also including: a decoder to decode an instruction requiring an input of a plurality of source operands, and an execution unit to receive the decoded instructions and to generate a result that is a product of the source operands. In one embodiment, the result is stored back into one of the source operands or the result is stored into an operand that is independent of the source operands.
