Patent abstract
An area efficient data shifter/rotator using a barrel shifter. The invention is a circuit, which uses a single barrel shifter and is controllable to implement either a left or right shift or rotation of bits of a digital data word. The circuit is dynamically controllable to implement left or right shift of bits of the digital data word (both logical and arithmetic) and rotation (to the left or right) of bits of the word. The proposed circuit produces the required output in a single cycle.
