Abstract
In one embodiment, the present invention includes logic to receive a permute instruction, first and second source operands, and control values, and to perform a permute operation based on an operation between at least two of the control values so that selected portions of the first and second source operands or a predetermined value can be stored into elements of a destination. Multiple permute instructions may be combined to perform efficient table lookups. Other embodiments are described and claimed.
