The present invention relates to a method and system for providing an N-way select instruction in a processor. Specifically, a method for providing an N-way select instruction includes decoding an instruction as an N-way select instruction. The method also includes selecting at least one pair of source operands from a plurality of instruction operands using information from a plurality of parallel control registers. The method, further includes selecting a final source operand from each of the selected at least one pair of source operands, and outputting each of the selected final source operands. In general, any N-way select instruction will have M=log<SUB>2</SUB>N stages of operation.
