Abstract: A method is described that includes fetching an instruction. The method further includes decoding the instruction. The instruction specifies an operation, a first operand and a second operand. The method further includes fetching the first and second operands of the instruction. The first and second operands are each composed of a plurality of larger chunks having constituent elements. The method further includes performing the operation specified by the instruction including generating a resultant composed of a plurality of larger chunks having constituent elements. The generating of the resultant includes selecting for each element in the resultant a contiguous group of bits from a same positioned chunk of the first operand as the chunk of the element in the resultant, the contiguous group of bits being identified by a same positioned element of the second operand as the element in the resultant.
