Abstract: An operand rotator (100) and method of rotating an operand is disclosed. The operand rotator (100) includes a first decoder (102) with a first input to receive an operand size indicating one of a plurality of operand sizes, a second input for receiving a rotate amount signal and a control output to provide a plurality of control signals. The operand rotator (100) also includes a rotator (104) with a first input coupled to the control output of the first decoder (102), a second input to receive a data element and an output to provide rotated data. The rotator (104) is responsive to the plurality of control signals to rotate portions of the data element corresponding to one of the plurality of operand sizes by an amount corresponding to the rotate amount signal.
