    Abstract: A processor is described having an instruction execution pipeline. The instruction execution pipeline includes an instruction fetch stage to fetch an instruction. The instruction identifies an input vector operand whose input elements specify one or the other of two states. The instruction execution pipeline also includes an instruction decoder to decode the instruction. The instruction execution pipeline also includes a functional unit to execute the instruction and provide a resultant output vector. The functional unit includes logic circuitry to produce an element in a specific element position of the resultant output vector by performing an operation on a value derived from a base value using a stride in response to one but not the other of the two states being present in a corresponding element position of the input vector operand.
