exemplary embodiments of the present invention disclose a method and system for executing data permute and data shift instructions . in a step , an exemplary embodiment encodes a control index value using the recoding logic into a 1 - hot - of - n control for at least one of a plurality of datum positions in the one or more target registers . in another step , an exemplary embodiment conditions the 1 - hot - of - n control by a gate - free logic configured for at least one of the plurality of datum positions in the one or more target registers for each of the data permute instructions and the at least one data shift instruction . in another step , an exemplary embodiment selects the 1 - hot - of - n control or the conditioned 1 - hot - of - n control based on a current instruction mode . in another step , an exemplary embodiment transforms the selected 1 - hot - of - n control into a format applicable for the crossbar switch .
