Abstract
A processor includes packed data registers, and a decode unit to decode a data element selection and consolidation instruction. The instruction is to have a first source packed data operand that is to have a plurality of data elements, and a second source operand that is to have a plurality of mask elements. Each mask element corresponds to a different data element in the same relative position. An execution unit is coupled with the decode unit. The execution unit, in response to the instruction, is to store a result packed data operand in a destination storage location that is to be indicated by the instruction. The result packed data operand is to include all data elements of the first source packed data operand, which correspond to unmasked mask elements of the second source operand, consolidated together in a portion of the result packed data operand.
