Abstract
A dual mode rotator capable of performing 32-bit and 64-bit rotation. According to a preferred embodiment, the dual mode rotator includes a first, second, and third rotator units wherein each rotator has a plurality of inputs and outputs. The inputs of the second rotator are operatively connected to the corresponding outputs of the first rotator unit. The inputs of the third rotator unit are operatively connected to the corresponding outputs of the second rotator. Responsive to selection of 32-bit rotation mode, the upper half of the inputs to the first rotator are zero and the lower half of the outputs of the third rotator are replicated in the upper half of the outputs of the third rotator.
